New Broadway Limited NP 4-8-4
Posted by Capt.Brigg on Monday, February 8, 2021 5:03 PM

I just received my new Broadway Limited NP 4-8-4 engine and am looking for advice on ways to improve performance. I've run it on our Willamette Model Railroad layout with LARGE curves and turnouts and it still stalls and restarts frequently. Both the 8 drivers and tender wheels have elecrical pickup and appear clean. Also the lead and trailing 4 wheels frequently jump off the track at a turnout. Both the front and back sets have a spring to hold the wheels down but they are very light springs. Any suggestions on making this beautiful (very expensive $900) engine rum smooth will be appreciated. Capt. BriggNP 4-8-4 engine

How does one obtain and install the Broadway Limited "GO Pack" keep alive circuit in my new NP 4-8-4 Paragon 3 decoder?

This thread brings back bad memories from years ago when I bought the BLI Paragon 2-10-2 and 2-10-4. Lots of starts and stops, front and rear trucks derailing, and the driver wheels derailing on curves.

It took a lot of running to overcome the starts and stops, but eventually those problems went away. I had to send both locos back to BLI where they installed stronger springs, and the front and rear truck derailments went away. As far as the driver wheel derailments, the blame was on my 24" radius curves, so I wound up selling both locomotives.

Several of my recent BLI locomotives have behaved just the way you describe with your 4-8-4.

Two of the worst culprits were both PRR K4 Pacifics. One had an older version of the Paragon3 decoder and the Go Pack had to be soldered in. The streamlined K4 had a later version (H) decoder that had the Go Pack plug built into the board.

Does your box have a yellow sticker saying it is "GoPack Ready" or words to that effect? Then it is a simple job of lifting the tender shell and plugging the Go Pack in.

There are instructions for soldering the Go Pack here:

 

I was pulling my hair out trying to figure out why both of these big, heavy K4s were frequently stalling. The older one has the big coast-to-coast tender with sixteen wheels!

Sometimes they would stall in random places but there were two turnouts that they would always stall at. These were #8 turnouts with powered frogs and I checked every rail segment for power but to no avail.

The Go Pack solved the problem. I've read several other reviews of recent BLI steam models and the stalling has been mentioned by others as well.

I still have issues with programming the address on the P3 decoders but that's for another thread.

 Good Luck, Ed

I think it's a combination of at least two problems with BLI steamers:

a. Their tenders are too light; and

b. Their drivers don't make good contact with the rails consistently, leading to continuity problems (hence BLI's introduction of the keep-alive bomb).*

Historically, I have had problems with my Paragon and Paragon 2 steamers where diesels and electrics don't seem to have those problems.  They can go for weeks running rather well and pleasingly, but then they start to stall, restart the decoder, and stall.  I haven't dealt with this problem constructively yet because I have other locomotives I can reach for, unpack, and put on the rails to complete a play session.  I suspect that the tires need a good cleaning, maybe the springs in the bearing boxes need cleaning, or something along those lines.  I can't help but wonder if Conducta-Lube might be a good solution at times on the wipers, but I don't have any and have never tried it.

It might be worth noting, too, that when BLI was selling their BlueLine, PCM, and Paragon models, none of them had de-facto traction tires.  They came along as a factory default starting in Paragon 2 somewhere, and they have been a staple ever since.  It was with my first Paragon 2 locos that I began to get the stalling problems.  Some worse than others.  My P2 Hudson and Niagara are notable examples, but my Santa Fe 2-10-2 and the I1Sa Pennsy 2-10-0 run very reliably.

All of my articulated engines, from a Lionel HO Challenger, to a Rivarossi H-8 Allegheny, to a PCM Y6-b 2-8-8-2, and the various BLI Hybrids run like Swiss watches. Same with my Trix 2-8-2 and a GG1..they run like tops.

*I said it's a combination of things, and in the case of poor pickup tire contact, the rails are often just as much at fault as the tires.  I don't mean they're not clean...most of us clean the bejaysus out of our rails, often several times in order to get our intractable trains to run.  No, I think it's the wobblin' and bobbin' that happens under the frames of our locomotives. The rail heights vary sufficiently over short distances that entire tires get lifted such that they lose contact, and they might have been the ones to keep things going while others were suspended.

After reading one of Ed's response to Broadway Limited engines in another MR post I decided to open the tender on my new NP 4-8-4 Paragon 3, revision "H" and check it out. It is ready for the plug in "Go Pack" and I have ordered one through my favorite hobby shop, Portland's Hobby Smith. There is also lots of room in the tender for the capacitor pack. There are several good videos in Youtube about installing the Go Pack.

I also found that the rear light on the tender is not lighting and there is a wired LED that should be working. I made a deal with the hobby shop that I would fix the rear light myself if they would discount the Go Pack. That saves them (and me) from sending the engine back to BLI. They were happy to comply. Thanks for the information. Capt. Brigg; CEO Pacific Cascade Raillway in HO gauge.

Sounds to me like BLI is trying to overcome poor design/manufacturing/pickup issues with the Go Pack "band-aid".  You shouldn't need a "keep alive" for a locomotive that large.  I bet my late 70s brass steam locomotives have better pickup than that BLI 4-8-4. Tongue Tied

I agree with you, Tom. It is inexcusable that a locomotive that large and expensive should need add-ons to make it run properly.

None of my older BLI Mikados have contact issues. Makes you wonder about their newer stuff.

Just to clarify, just the paragon 3 motors/boards. Their paragon 2 stuff was fine.

I agree. I remember getting my first P3. It was the PRR H10 and it stuttered and died from the first moments I placed it on the track. BLI sent a new decoder which I replaced. No improvement.

Then I sent the engine to them for another decoder and harness replacement. Got it back with still no improvement. Put in an ESU decoder and it has been running fine ever since.

Also 3 BLI heavy pacifics, plus the two K4s, a light Mikado, all 3 of my P5a electrics (all 3 motors bad, too) all had decoder issues and even after "factory service" they're still behaving badly. 

I've budgeted replacement decoders from other vendors for all these engines in the future.

Something went bad with the addition of the "Rolling Thunder" transmitter to the board. They need to reevaluate their electronics from the ground up.

I have posted the story before about what I went through with my BLI 2-6-6-4, so I am not going to type it all in again.

They have problems, and they need to do more to help their customers when we get stuck with those problems.

Spending that kind of money on a model, we are well within reason to expect flawless performance.

All seven of my BLI/PCM steam locos run great...........

After I rebuilt two from the ground up and removed the decoders from the five that came with decoders and rewired them for DC. (Two were "stealth" models from the PCM days)

And those five all have Bachmann tenders now.......

Ironic that a company that impresses me as selling the sound experience as much or more than the model experience has so much trouble with electronics.

None of my $200 Bachmann locos have these problems, but then again they don't have decoders either........

I see no more BLI locos in my future, unless they are dirt cheap for me to invest in rewiring them.

Did I read someone mention tender weight? Yes the tender is likely too light for good tracking and electrical pick up. And yes, a long rigid wheel base like this will be fussy about track, even with sprung drivers.

I would have done the same thing if I would have never sent the 2-6-6-4 back to BLI that last time. Now I have an empty spot on my roster, oh well.

My only other articulated locomotive is my Bachmann 2-8-8-4, and it is many times over a better locomotive than the BLI 2-6-6-4 was.

Ive resorted to only buying paragon 2 stuff. I love the paragon 2 sound, whereas I dislike the p3 sound. P3 also has those bugs, yet more expensive. When you're someone like me who prefers buying discounted used, there is very little reason to choose p3 over p2. The only p3 engine I got is the L1s which I have yet to have any major issues with. 

I'll also be getting two of their Santa Fe 4000 class 2-8-2s...wish me luck. 

Im genuinely curious how many modelers are using the rolling thunder system...considering how hard bli is trying to market it.

My $60 sound Bachmanns had less trouble than BLI, sure the sound is better on the BLI but we are comparing a sound value vs a top of the line.

Im genuinly curious how many modelers are using rolling thunder feature to the point where getting BLI investing in P3 decoders is worthwhile.

Charles

I only have one BLI Paragon 3 locomotive: An SW7 switcher, which I'll most likely sell because I don't care for the gearing.  I know that Ed purchased the Rolling Thunder speakers.  I have zero interest in it.  It's more of gimmick and it wouldn't add any additional enjoyment for me.

Indeed, its like BLI's version of DCS, where the feature will only work with their own engines...so its only worthwhile if you stick with BLI and only BLI. Not to mention Im happy with how my engines currently sound.

I have had similar problems.  I opened the tender and traced the tender pickup wires back to the decoder.  On mine, I found the male end of the tender pickup wires to not be properly seated in the plug itself.  I pushed the wires into the male end of the plug and most of my engine problems went away. 

Now, if the engine does stall, I lightly touch the coal load on the tender and away it goes.  So the next time I open the tender, I will add a little weight (maybe 15 grams or so) and determine if that resolves the problem.  If that is unsuccessful, I will install the BLI "keep alive".

It is a beautiful engine and I waited forever for it to become available. When it is running well, it is impressive and pulls my NCL varnish nicely.

 

Yesterday, 2/24/21, I installed the BLI GoPack keep alive and the engine now runs fine.  Hurray!!!!

I know that Ed purchased the Rolling Thunder speakers. 

   — and a week later packed the whole thing up and sent it to Cuda Ken. He has been enjoying it on his layout.

I can't say, in my experience anyway, that tender weight is the culprit here. The poor electrical continuity seems to have reared its ugly head with the transition to Paragon 3. Again, most users seem to not have the problem with earlier P2 and QSI locos and the tender weight hasn't appreciably changed with the P3 introduction.

Just last night I dusted off an old QSI-equipped Hudson I had purchased in 2002. It hadn't run in years and when I ran it last night it was performing without any signs of trouble.

Something seems to have compromised the design with the addition of that P3 "rolling Thunder" transmitter that is piggy-backed on the board.

The transmitter is the smaller board on top with the blue antenna wire.

Something that I have never been clear on. Are the Paragon 3 decoder problems limited to BLI's steam engines or are BLI diesels affected too?

I have four Paragon3 diesels and they seem to be OK.

You might consider the P5a electric a "diesel" since it is mechanically similar. Somehow a bad batch of motors got in to these. Incidentally, about the same time Rapido was having motor issues with their RS-11 and RS-18 Alcos, of which both of mine needed motor AND decoder replacements performed by their service people.

In the case of the BLI P5a the three I have needed new motors and decoders. BLI provided the parts free of charge and I did the repair work myself.

I have two Paragon 3 GG1s that run just fine as well.

Another note, both BLI and Rapido gave me excellent repair and/or parts replacement service.

A further issue with Paragon 3 which I haven't mentioned yet but seems to have affected certain decoder versions is the inability to program certain four-digit addresses. In four situations I have had trouble programming the road number as the DCC address. Very odd behavior.

BLI claims they have corrected it with revision H but it still persists even with new, replacement decoders from them.

Very interesting. I dont see why the transmitter board would make the engine much more sensetive to dirty track, besides maybe the fact that increases current draw, making the stock small capacitors drain faster over interuptions. 

What exactly was the issues with the motors? Do they not spin? Do they draw more current? Was there a visual difference between the bad motors and the replacement motors they sent you?

High current draw that would overload the motor output circuitry on the decoder. Ones I tested would draw 1.8 amps at 10 volts, no load.

The replacement motors were identical on the outside appearance. They already had the flywheels and plug attached.

I heard about the pitfalls of opening up the Rapido Alcos so I decided to let them do the work on those so I can not comment on what their motors looked like.

Trainman440
I dont see why the transmitter board would make the engine much more sensetive to dirty track,

I don't mean to imply that the Rolling Thunder transmitter itself is at fault but I'm saying that somewhere in the design process of adapting the socket and related circuitry something, maybe a certain component, seems to have compromised the functionality of the decoder itself.

Trying to diagnose the PRR Streamlined K4 I spent hours, usually at the suggestion of the BLI service tech, trying to make headway at a diagnosis.

After a hard-reset everything would work perfect on address 3. Programming the road number into the decoder would eventually lead to odd and erratic behavior.

Motor direction would go haywire. Engine would stop, then restart in the opposite direction at random times. Engine would take off at 100% speed with only notching throttle to speed step 1 then there would be NO control. I had to kill layout power to get the engine to stop. BLI suspected the Digitrax command station. I reset everything (and even bought a new DCS240 just to be sure) but the problem persists.

Sometimes the motor would not respond at all but all of the related sounds and lights would work fine. Sometimes I would write an address to the decoder and on reading it back an entirely different number would be shown!

It has its third decoder in it and I can only use certain addresses and NO four digit addresses. Presently it will only run on address 3 or 8.

This type of behavior, the inability to program certain four digit long addresses, happened once before, but I cannot immediately recall the manufacturer of the loco or the decoder. Let me use the search function to find it.

Huh, I wonder if its a digitraxx thing. Id assume its not, Ive heard similar issues with NCE and the such.

It sounds like there's some sort of interference between the controller's signal outputs and the decoders signal inputs. Maybe the bridge recifiers are bad. Maybe the capacitors were incorrectly wired. Maybe the decoders are lacking a frequency filter and possible outside interference is messing with the decoders. 

Id like to get my hands on a few faulty decoders and try and diagnose what's exactly going on. 

Either way, it sounds like not enough time was put into R&D or QC, which led to these faulty decoders which is hurting BLI in the long run, having to return and offer repairs to engines. 

Another reason I will be avoiding buying used P3 engines.

Hi, Charles.

This is part of the reply I got from BLI tech. while attempting to diagnose the K4:

Regarding Digitrax, I wanted you to try a different address as an experiment and it is kind of leading us to what I suspected.

I do remember the weird bug with Paragon2 that was "take the address, subtract 315 from that number, divide that by 256 - if it divides evenly then you need revision 15" - very obscure and I can assure this is not that.

That was corrected in Paragon2 and that correction carried over to Paragon3.

This is why I wanted you to test with a different address:

If you are running a Digitrax system with a dual throttle controller - sometimes a loco can act like it has a mind of its' own. This can happen if the same address is stored in the left and right side of say, a DT402 for example - even if one of the sides does not have the address called up in the window it can suddenly start getting commands from the state of that (old/duplicate) stored address and then switch back.

For example:
You run the engine one day on the left throttle at DCC address #2000 and then you throttle down and pull the loco off the rails and shut down the system.

You never run that address again until 3 months later when you call up DCC address #2000 on the right throttle. Let's say the left side of the throttle now reads something like DCC address #636. The engine is moving along at speedstep 40 of 128 (right knob/throttle), and then suddenly it will get the command from the left side that was there 3 months earlier of speedstep 0 - even though it's not present in the window. Then, it gets the commands from the right side again and takes off back up to spedstep 40. It looks like the model has a mind of its own.

I have seen this and replicated it on our layout with the DT402 numerous times and I've helped a lot of people with this phenomenon. I'm not saying that is what is happening for sure - but the only way to be certain is to try it on a different layout, and/or try programming a DCC address that you know FOR CERTAIN you never would have programmed into a loco before.

If it stops "misbehaving" after trying those things - then contact Digitrax on how to completely clear out all stored addresses in the Digitrax throttle and system and then try running the model again.

I had cleared out all addresses, and as mentioned, installed a completely new DCS 240 (not specifically for this cause, I was going to get a new command station anyway) but the addressing problem continued.

Even with the replacement decoders I couldn't get the decoder to keep a working four-digit address. On another locomotive with a P3 decoder, it was an Erie heavy Pacific engine #2925.  The decoder absolutely refused to recognize that number. I could program one number up or down with no problem but try 2925 and its brain would get scrambled.

I could set it to 29 OR 25 but not 2925 Bang Head

This engine now has a TCS WOWsound decoder in it.

Huh, I wonder if its a digitraxx thing. Id assume its not, Ive heard similar issues with NCE and the such.

It sounds like there's some sort of interference between the controller's signal outputs and the decoders signal inputs. Maybe the bridge recifiers are bad. Maybe the capacitors were incorrectly wired. Maybe the decoders are lacking a frequency filter and possible outside interference is messing with the decoders. 

Id like to get my hands on a few faulty decoders and try and diagnose what's exactly going on. 

Either way, it sounds like not enough time was put into R&D or QC, which led to these faulty decoders which is hurting BLI in the long run, having to return and offer repairs to engines. 

Another reason I will be avoiding buying used P3 engines.

I understand that DCC and sound are important to a lot of modelers today, and that it is a significant factor in the future of the hobby.

And I also understand that model train electronics are not cell phones or tablets, or gaming PC's.

But I have to think too much work is being put into trying to out scoop the competition, and not enough work is going into having a solid reliable product.

Just like I feel Broadway has missed out by completely turning its back on modelers not interested in sound, or modelers who might prefer to install the decoder of their choice.

But I could be wrong......

But I know this, I look at Broadway models and while nice, the detail levels do not "wow" me. The steam is a little better than the diesels, which I still feel are out classed by a number of other brands, current and past offerings.

What kind of psycholgy accepts having to return $700 locomotives for repeated repairs but then calls $300 Bachamann locos "junk" because the decoders have less features, or because the loco benefits from some small tweak most anyone with a basic mechanical aptitude can do on their own?

Don't get me wrong, even though I am a "model builder" type, I like the new RTR world as well. It lets me build the large layout I am about to start and allows me to "save" my building skills for the important projects.

I don't really have a dog in this fight, there is nothing in the BLI catalog right now that would part me from my money.

But that says something about an ever growing divide in this hobby.

I know I'm stuck in the past, I tried DCC and just could not warm up to it's "importance", sound even less so.

It seems unfortunate that BLI has been plagued by just as much or more quality and reliablity issues as many companies making less expensive items for our hobby.

I try not to pick too much at any of these companies, they have a tough job. But as a consumer I do vote with my wallet.

BLI has only managed to supply 5% of my reasonably large locomotive fleet...... and many of those few BLI items purchased at "liquidation" prices. 

Even if I used DCC and wanted sound, these reported problems would not inspire me to spend $700, or $900, or even $400, on my next locomotive.

I submit these thoughts as simple observations from my 53 year perspective of the hobby.

I like to see everyone find what they are looking for in this hobby, and I fear this has become a nearly impossible task for the manufacturers - BLI, or Bachmann, or Athearn........

Lol Sheldon I've been intentionally holding down my desire to reply to your comments. But now that youve directly quoted me I guess I must do so now. 

There are so many points Id like to address, but I feel it would be a waste of my time and yours to rehatch old discussions.

The simple fact is, I get it, there are people who dont like the complexities of DCC, and find DC perfectly suitable. And there's obviously nothing wrong with that, I completely respect that. But just because you dislike DCC doesnt mean DCC isnt a valuable asset in part of a model. 

But I have to think too much work is being put into trying to out scoop the competition, and not enough work is going into having a solid reliable product.

I think BLI values QC just as much as the next, but theyve made a blunder...just like Bachmann did when they used to use cheap white nylon as axle gears. Sh!t happens, and I respect BLI for holding their customer service and offering repairs and free replacement (parts) for their troubles. 

Just like I feel Broadway has missed out by completely turning its back on modelers not interested in sound, or modelers who might prefer to install the decoder of their choice.

BLI has its own reasons to force their own decoders in their engines. Financially, it makes perfect sense for them to do so. I know it makes those who dont prefer their decoders angry for having to pay more (or simply not buy them), but honestly I commend BLI for creating their own decoders. It increases their profits in the long run, and I will always commend any manufacturer who decides to dive into different markets. 

However, any manufacturer who's trying new things will bound to have failure. BLI doesnt specialize in decoders, and so obviously theyve made a mistake. Im sure they are more than well aware of their fault. I dont think people like me or you complaining is helping anyone. Sort of like how their first model the J1e had issues with the mechanisms, and they offered upgrades to those who wanted a newer version. 

I think from a design standpoint, their models (not decoders) are just as good as Bachmanns. This is clearly opinionated, but I find BLI models to be more detailed.

For example, a common model I know you like to compare is their USRA 2-8-2s. While Bachmann's has some prototype specific detail, such as the raised/lowered headlight, and various trailing trucks and tenders, BLI models are more detailed. In closer inspection, Bachmann's 2-8-2 has far more molded on piping, smooth(non-textured) running boards, simplified, crude details, etc. They have stamped metal driving rods, no bearings on the wheels, and wiping pickup. BLI's 2-8-2 has no prototype specific detail. They resemble the as built versions of each USRA 2-8-2. They have superior detail, more separatly applied parts, thicker driving rods with depth, walkway tread, etc. They got copper bearings on the wheels, a split chassis for bearing pickup. Yes, they lack prototype specific detail, but they overall have far more detail. 

I have no clue where Im going with this, but I am saying that there are very good reasons to get a BLI model. If you're looking for value, or a good candidate for freelancing or kitbashing, then Bachmann's models are great. If you're looking for a more refined model(ironic how they've had more QC issues, but you gotta take the good with the bad), with better overall detail, and you happen to model the big, "cliche" railroads (like me!), then BLI models work great.

Their stuff is expensive, that's why I buy nearly all of mine from the used market. They really hold their value and their engines will last a long long time. If you love comparing prices, and value means a lot to you, like Sams Trains on youtube, then I understand why you see no value in getting a BLI model. Money is tight for me too, so I get my stuff on Ebay. I've gotten over 8 "baldwin 2-8-0"s by Bachmann for around $50 each. Ive owned 2-10-0s, USRA mountains, and even a berk. They are fine models. But they cant replace my BLI I1sas, or ATSF 2-10-2s. 

I model the PRR and ATSF, and Bachmann simply dont make any engines with those prototypes (except the K4, which Ive owned 3). 

As a "cliche" pennsy modeler, I feel blessed to have a manufacturer sell models which satisfy my detail and operating needs. Yes, theyre expensive, but it makes my job a lot easier. Without BLI, only the K4s is purchasable in plastic. Everything else (A5, B6, G5, C1, H9, H10, E6, I1, M1, L1, J1, etc) all had to be brass. I love my brass engines and love an engine I have to put work into to bring to my standards, but being able to buy some of that in RTR form is a relief. I think a good mix of RTR and custom brass is a good mix. That's why BLI has my money. 

-----------------------

I guess what Im getting at is, Bachmann models are great, and they obviously have a place in the market, however it doesn't mean therefore that no one should buy a BLI model. Non-freelanced modelers often buy based on a model's prototype, not by brand.  There are reasons to buy models from each manufacturer. You can compare all the models you want, but until Bachmann makes the same exact engines BLI does, and better AND for less, I'll be sticking to BLI for my PRR and ATSF needs. 

PS The only two non-diesel locos that both Bachmann and BLI have made that Im aware of is the GG1 and K4s. Both of which BLI's are farrrr superior.

PPS I agree that BLI models are expensive, I dont think anyone's gonna argue with that. But supply and demand laws dictate that BLI has more than enough customers to which they can charge a pretty penny for their (clearly desireable based on their sales) models. The only BLI model I ever bought new was a PRR L1s. Every other engine Ive gotten used, and cheap. 

-------------------------------

I can understand as a freelancer why spending ridiculous prices for a single model is crazy. But if you were a modeler dedicated to a specific railroad, you would be much more willing to buy certain rarer engines.

Im far from being a prototype nut, but a Bachmann USRA 2-8-2 in PRR scheme will not cut it for me to replace a BLI PRR L1s. 

Hopefully that atleast explains why I will continue to buy BLI models.
