In "HO" that's what they did! Engine and control to NMRA Standards.

They built the K-4 to NMRA latest standard. It can run on MTH "DCS" control OR the "DCC" open NMRA design. All DCC functions can be used with a Power Supply built to the latest NMRA standards. The "MRC Prodigy Advance" is one such unit. An MRC problem in DCC f13 to F28 functions did existed on early MRC units. MRC will correct it for free.

Most of us agree with you "Count me out on this one. "

I only use DCS for the two #1 scale engines, but it is designed for the functions and options that are built into those models.  They run on DC also, but work much better on the DCS.   I purchased the system just to run the two engines, provided they were on the track in the correct direction.  

The funny thing is, I was told by MTH technical representatives my DCS system will not run the HO model MTH K4, so I did not buy one.

From what I have read in the MTH DCS ad, this system doesn't sound that appealing to me either.  Maybe it's just me, but MTH just seems to be full of themselves, and trying/wanting to make the whole model railroading hobby an entirely MTH "exclusive" item.

The #1 scale engines sounds are extremely good.  I can credit some of that to the larger speaker in the tender, but they use the 3985's whistle and bell sounds for the 3985 and they use the 4449 whistle and bell sounds for their 4449 model.  It is as good as it gets for both of these.  They also chuff correctly and are very convincing for model trains with the exhaust exactly timed to every chuff.  The Challenger actually times the double chuffs with the smoke even when they are running in and out of sync. 

The DCS system operation does have operating limitations, but the sound itself is great.  I noticed that shorting or overloading the track will cause the DCS driver in the Track Interface Unit to blow out.  This is a problem that happened twice to my TIU and it had to be sent back in for repair.  No Fuse??

It just proves there is no perfect system.

Thanks for the information about the switch.  I did locate it, and you are right, the Challenger does not have it.  I was thinking it would be automatic, not manual.  It is still is a problem with any operation except a giant loop.  This means you would have to have reverse loop switch wired much like standard DC opertion.

Thanks

Lionel is still operating on borrowed money, but, with the backing of LARGE banks and new managment they will servive and prosper.

It would seem logical that a new and updated change to correct the directional deficiency would be offered to the previous models.   MTH should offer this correction to all of the previous models out in the field.  I also have the Daylight and it has the same problem.

Do you know if this modification is available for upgrading my two models?? 

I credit MTH for their working with the Union Pacific to solve the problem of the use of the names.  This was a good thing and all of the manufacturers and modelers will benefit greatly from this.

As an O scaler, (and I commented on this about a bazillion posts ago) I feel that the ill will in the O gauge world has done nothing but pollute the well of potential converts to the King of Scales!
I model in O scale, 2 rail, and still use good old reliable DC control! I am considering DCC, but, I am not a big fan of more complications in a hobby.
As far as a supplier/manufacturer, I prefer Weaver!
For the most part made in Pa. (some limited runs are imports), and they are priced to buy.

It doesn't do any good for O scaler's (oh I'm sorry, O "guagers") to come and preach the MTH gospel here. The writing is on the wall for MTH and their goofy little DCS system. They blew it early on and have generated quite the negative attitude since.

BTW, if I was going into O, I'd be buying Atlas O! The detail on those engines is astounding! Sure they use TMCC for 3 rail aplications, but both MTH and Lionel could both learn a few lessons from Atlas O locomotives!

I read about the greatness of DCS over the Lionel system, but that is three rail and it must be somewhat different from two rail operation.    Try two rail DCS as in #1 scale.  I purchased the Challenger two years ago and the DCS system for the two rail track.  It is very interesting and has great sounds since the large speaker in the tender can really make the whistle sounds as they should be and the chuffing is extremely good.   

If you set the engine on the track facing the wrong direction, the DCS system reports the engine is not on the track or it is out of RF range.   The model has to be re-positioned on the track or the leads have to be reversed to run the engine in DCS mode.  

I don't see the # 1 scale as a highly advanced system but I realize the HO version will run on DCC or DCS.  It must be a later version of their software, but the #1 scale is very limited to a giant loop of track with your engine facing a certain direction.   I enjoy the model since it is a great looking engine, but it has many limitations that I would like to see corrected.  DCS will not be the next step for my HO use.   

The service department repaired my DCS unit two times at no cost.   If you lay anything on the track, it seems to blow out the DCS driver that allows the unit to talk to the engine in DCS mode, but you could still run it in DC mode.   It is too tempermental for my use outside. 

Overall, the model is nice and fun to run but not pratical for outside use.   I would still buy it again just for the value of it as a display item.

Why is DCS the best?

Lionel in "O" is the largest company and has the "TMCC/Railsound" system. They will "license" others to install "TMCC". It is 3 Rail AC.


MTH is the second largest and uses DCS only in MTH Electric Trains, BUT!!!
It can run both MTH and Lionel products in Command Control. It can run a locomotive in ether AC or DC. It can run ether 2 Rail or 3 Rail. It can run in ether Analog or Digital. It uses a screen on the hand held Remote to read what you are doing. It can run "O" gauge, "G" gauge, and now "HO" gauge. Updates to DCS (software allways has problems) can be downloaded by the Internet for FREE. Don't like your Locomotive sound, download a new "file" from the Internet.

I collect "O" gauge and run "G" gauge, I have MTH "G" locomotives and have upgraded 3 Aristos to DCS. Control/sound upgrade kit $150 (too big for "HO"). IF, IF, the "HO" can be made compatible with DCC, upgrades in both "G" and "HO" would be easy. Buy the way, the sound level control is a must for outdoor operation.

You have made an interesting observation that I had not heard comparing the MTH DCS to the Lionel system.  It might be we have all been thinking in like terms for all of the scales and uses, but they really do differ.  I noticed that early on in this subject, someone was talking about the track and the fact it did not have to be cleaned with the three rail, at least very often.   That probably is true since the engine weight is so greater and the third rail roller or wiper is spring loaded and has force behind it. 

In HO, we depend on gravity and most of the latest engines are plastic with some weight added.   The lack of weight and the much smaller two rail system has to be much cleaner.   This is the reason some of the latest sound locomotives have given problems to new owners that simply ran dc or a few DCC a lived with the problem of dirty track or poor contacts.

Thanks for the observation.   I don't have three rail, but it does sound like DCS is an improvement. 

I can remember when we use to run the American Flyer, we would run the trains to clean the rails and you could smell the sparks when you first ran it after it set unused for a time.   The point is, it would clean up because of the weight and slider tender pickups and start to run good.

- I have to admit that I was happy and quite surprised as Athearn reps told me several times since 2003 that updating the "Cowls" was not on their list.  Glad to see that they had a change of heart. 

The DCS and MTH advertisement for HO is interesting to me since it has been going on for so long, any word of it being available and actual viewing of the product may be anticlimactic to our forum.  I read last week that the models were in shipment
-  I'm pretty sure that the "Big Story" will break when the LHS's get their first units. We'll be seeing threads pop up here, that's for sure! 

I've been following the MTH threads ever since the big hoopla back in 2004.  As I stated on another MTH thread, it's like watching a tired old soap operaSleepy [|)].....but we keep tuning in regardless! Wink [;)]

Well Caz, you know the situation.  Most of the technical "speculation" that's been discussed has been based on DCS application in O scale, which of course has very significant differences when compared to HO.

Just as with new products all we can do is wait and see.  Even after it hits the market it may be a while before we read or hear of significant numbers of customer feedback.  Of course, IMHO, MTH's competitor's such as Digitrax, Lenz, NCE, QSI, BLI/PCM, etc will likely purchase units as well for laboratory "dissection".  Typical sauce for the goose........or business as usual.

Jerry,

I would hardly call you a Little Raincloud... [;)] I do think that R2 of yours is being a bit tempermental, but as you didn't mention another locomotive I'm not sure if you have one problem child or many. I can tell you the battery issue is real, and keeping it charged is very important for optimal operation. This usually doesn't come up with my layout as all the locomotives are on the layout and always charging when in operation which is pretty much everyday.... [:D]

As always you make good statements based on your experiences, and it sounds like they haven't all been happy ones. I'm very sorry to hear that because I think your view of DCS would be quite different if your experiences had been positive ones. I also have a slew of questions to be answered before jumping on PS3 bandwagon (reverse loops being one of the most important), so I'm sort of in the same boat as you. I have decided to buy a K4 a gut it for an On30 test, so I should know more in a bit.

Thanks as always for your posts! Even though you don't feel the same way about DCS the way myself or a few others do, you make good arguments and your posts are always good reading!

As to the dirty track issues however...

I find myself chuckling when someone tries to compare the track cleaning requirements for an HO scale DCC equipped layout to that of an O scale 3-rail DCS/TMCC equipped layout. While I agree dirt is a problem regardless of scale when using track power, I've never had to clean my track to run my 3-rail trains, even after months and months of use. Sure things will get dirty enough to cause problems, but this is typically after a great deal of time has elapsed, and even then the problems are minimal. On the other hand, several of the HO scale clubs I operate at have nothing but nightmares with track cleaning and many an operating session has grinded to a halt because of this. All of them clean track prior to every event with various methods, and still there are always bad spots and power loses.


Experiences with dirty track vary greatly from user to user. On my basement sized HO railroad, with dirty track in a DCC environment (flunks the white glove test), with a rolling stock fleet that exclusively uses metal wheels, with track that is oiled, I do not have issues with dirty track. The motive power consists of Stewart F unit drives, P2K GPs and FAs, some older Tenshodo GN power, a few Key Limited brass NP articulateds, etc. I have two locomotives that DO have problems with dirt (and need cleaning of their wheels and pickups), a P2K 0-8-0, and a Bachmann 2-8-0, and that is largely due to the design of their pickups. Given their poor reliability, they don't get used anywhere near as much as their Tenshodo equivalents.

My hirail experiences are exclusively on a modular railroad built to Independent HiRail standards. GarGraves track, with Gargraves, Ross, or Curtis switches are used on the RR. I've witnessed DCS signals deteriorate on setups within 10-20 laps on our smaller layout setups, starting at 10 and deteriorating to 2 or less. (it doesn't run on our medium to large layouts, and we haven't went the star wire route, and probably won't). For that matter, I've seen deterioration in performance on TMCC equipped locomotives when run for a couple of hours (last year with a K-Line 2-8-2 light mike).

The modular railroad sees traffic density far greater than a home layout. It also sees a plethora of equipment, and I sure can't attest to the cleanliness of the wheelsets that run across the railroad during a show. All I can say is I am surprised, and disappointed, at how sensitive three rail motive power seems to be to dirt, and I don't care if the locomotive is DCS or TMCC controlled.

QUOTE: Honestly, it would take a slew of scientists and a battery of hands on tests to convince me how a 10-12 ounce HO scale locomotive with pickups through the wheelsets on 2 rails could have better electrical conductivity than a 5-6 pound O scale locomotive picking up power from two outside rails for ground and a center rail for power.


The weight has absolutely nothing to do with the equation, at least as far as the three rail beast. The weight on drivers only affects the common side of the circuit. The hot side takes it's feed from the center rail, through rollers. The only force on that roller is the spring tension on the roller, plus the negligible weight of the roller and bracket itself. For simplicity, we can assume that the contact patch is probably roughly equivalent to the contact patch of an HO wheel on an HO rail.

That would mean that a locomotive in a two rail application (don't care which scale), will probably perform better than a three rail application as there would be more contact patches per locomotive to pick up power on the hot side. The only way this can be confirmed however is for that fine MTH K-4 to get some track time in DCS mode on several railroads to determine just how well it works. I'm still waiting for MTH to come over to my railroad to run a test with DCS. [:D] I have some reverse loops I'd like to see how it handles. [:D][:D][:D]

QUOTE: Having an On30 layout and N scale layout using DCC at my home, I can surely attest that my 3-rail setup is virtually maintenance free in comparison. Jerry, it makes me wonder what kind of track you've used with your 3-rail stuff. I know the any of the phantom center rail stuff will cause huge problems if not dealt with. I have used Gargraves in the past with some success, but my current layout is done with the new Atlas phantom stuff, and I made sure to poli***he top of the center rail before it was installed.


As stated above, my modules, as well as all other modules in our group use Gargraves track with a combination of Gargraves, Ross, and Curtis switches. Our track is cleaned before the start of every session, and on shows with setups over more than one day, we run a Centerline track at the start of each day.

Regarding your comments on the Atlas phantom stuff, I have experience with it also, as the home railroad that I talked about is built with that track (I am helping build it). That railroad is designed with DCS in mind, and he has stripped off all of the blackening from the center rail, as well as using OGR twisted pair wiring, and hanging about 12 lightbulbs around the railroad.

So recently, I go over to his place, and I bring my MTH Great Northern R-2 to test run. He fires up the railroad, and moves a couple of his MTH steam engines around (a WM Consolidation, and CB&Q 0-8-0), and everything is running wonderfully. I put my R-2 on the track, acquire the locomotive, and go running around the RR for about five laps. Works like a dream. Take it over to the turntable, runs on just fine. Spin the engine around and I get the "No Locomotive Found, check track circuit". No problem, I figure that the problem is the turntable. Move it, and try again. Locomotive acquired. Run it around for about 1/2 lap, and it "gets lost" again. The only way I can reacquire it is to physically remove the whole locomotive, set it back on the rails, power up the DCS, and try again. Works for another 1/2 lap or so, then the same problem. Get disguisted, put it back in the box. Write post to the OGR DCS board to try to learn what might be the problem. Evidently, there is a battery that can discharge, and if it doesn't hold a charge, the loco acts up. You won't have that problem with a DCC locomotive with sound, as there is no battery.

Maybe you can call me Little Raincloud, but my DCS experiences have been anything but pleasant. I have NEVER encountered this level of frustration with my DCC HO railroad.

QUOTE: Of course through all these discussions I realize that everyone has had different experiences to different products. Some seemingly make no sense to others as the problems are so isolated to one layout or user. Honestly I have no idea how well DCS will fair on a 2-rail HO scale layout. I can say that the new PS3 boards are supposed to be significantly more sensitive to the DCS signal than the PS2 boards are, and there is a heavy dose of capacitor backup for brief track power losses built in. Also, I have read several reviews of the K4 now under DCS power, and none of them has said anything about track power issues so I'll keep my fingers crossed.


I have no idea how DCS will perform in a two rail HO environment either, but until MTH does some real world demonstrations on actual model railroads, we aren't going to know, are we? I'd like something other than Andy Edleman marketingspeak on the "robustness" of MTH DCS to convince me that this is a better solution than DCC.

Buy the way, 5 or 6 pounds, come on , move up to a 25lb MTH Big Boy. [:D]

I think your experience with DCS is more typical.


Dave,

So you're a night owl too... [:D] You know I'd love to have a 25 lb Big Boy, but without the requisite O72 curves and lot's of clearance around those curves it isn't going to happen anytime soon....[;)]

I agree completely with your thoughts about wiring issues and command control, but I still find the track cleaning problems to be very minimal on my layout. Maybe it's my location within the US (very dry most of the time) or I'm really lucky, who knows?

Night!

Jeff
