Did you ever notice that if you run 2 or more powered diesel locos in your consist,it runs more realistically?

I like to run my Stewart Hobbies Pennsy U-25b lashed to my Atheran BB SD-9 and the train runs smoother and just more realistic.I run a ten car consist on my 4by 8 test layout.What do you think?

I agree, however, when I throw a couple of mid-train helpers into the mix, I think that is even better. The first time I ever did it, I was waiting for disaster to strike, but it never came and never has. Three "F-units" up front and a couple of train masters in the middle with 60 cars are pretty cool.

One of the things I noticed when I added keep-alive circuits to my re-motored Athearn BB F7's was that they could be run much slower with no hesitation.  A pair of these locos will pull a train around my 10' by 19' double deck layout at around 5 scale miles per hour all day long!

Hello All,

I run several consists on my 4'x8' pike.

A 4-unit consist of GP40s pulls a 16-car coal drag on the mainline, half the cars are empties.

The 8 loaded cars are cut out and a 3-unit A-B-A consist of GP30s; one on the head end and the A-B units are used as pushers up the 3% grade to the unloading platform.

The 8 empties are pulled under the platform by the GP40s to receive the live loads.

A single GP30 guides the empties down a wooden trestle (helix) back to the mainline and coupled to the now loaded hoppers.

The GP30 A-B units back down the 3% grade and are MU'ed back with the single GP30.

A cow & calf unit; TR & TR2- -NW2s- -is used for switching the power plant and the rock dust unloading siding that feeds the coal mining operations.

My MOW train has an F7B pushing the rotary snow plow on the head end, an RS3 as a mid-train helper, and a BL2 on the rear pulling the secondary rotary plow.

A USRA 0-6-0 w/Vanderbilt tender powers an "Olde Tyme" excursion train and a 0-6-0 Side Tank Porter is added to get up the 3% grade.

On rare occasions, the Royal Gorge excursion train, with its A-B-B-A F7s makes a pass on the mainline to connect with the "Olde Tyme" excursion train for a rail fans dream.

With the GP40s, the 30s, and TR & TR2 I re-motored and standardized the decoders for each consist.

This allowed for easier speed matching between the units in their respective consists.

With the GP40s I can have two on the head end, one as a mid-train helper and the fourth as a pusher.

With all units powered in the consists it definitely adds the required pulling power and looks great too. 

Hope this helps.

I wonder if the guy who put a powered loco in the middle was concerned that it would cause string lining or a massive derailment?

I was waiting for it, but everything ran smoothly. A derailment on my layout rarely happens and when it does it is because some idiot Whistling failed to check a turnout. I was and still am surprised that mid-train units don't cause me any issues.

If they are properly speed matched this isn't a problem.

That's why I re-motored and standardized decoders in each locomotive in a specific consist.

Hope this helps.

Thanks guys !very interesting replies and if you can truly run 30 freight cars it is most impressive!

I can understand that they can run with less hiccups, but what do you mean by "more realistic"?

Hard to put my finger on ,but the lash makes them run smoother with the momentum feature activated.

More reason for me to increase my loco fleet.  With three locos and a switcher, def need more.  I guess somene has to keep the N&W product line flowing!

  Perhaps on DC. I have zero issues running single on DCC. Adding momentum to the decoders and speed matching so you can add helpers works.

  I have steam switch engines that by design run slower than anything else I have. They do not get consist with road locomotives.

Few steam engines run as well as fly wheel equipped diesels (which they would)

   Like I said. Maybe on DC. If you're running DC, after the power is cut then flywheels is all you have.

  I think you would be surprised. I have non flywheel steamers that run awesome. I even have open frame motors in some. Adding the right amount of momentum and deceleration is key. I used to just add a little. But with modern decoders with BEMF, braking and other features, you can tune any locomotive to act like the prototype loaded or running light.

I think you refer to these new fangled Digital Control Systems not really into that!

  I have been using Digital Command Control for at least twenty five years. Newfangled? No. But that is the beauty of the hobby. Do what you like and I can do what I like. I like running trains, not track.

    Have fun.

Well, I think there is something to the OP's query.  In running consists of locos - anything from multiple GPs, Fs, or Es, I found it was definitely more realistic than running single units.  But there was more to it than the visual, as (IMO) the sounds of the consists seemed to give out a better show of raw power.

The thing is, it was the same "sense of power" whether they were sound units or just motored w/o sound.  I guess even the sounds of the bare electric motors and gears just promoted the "feel" that these locos were truly working, pulling their loads.  

On my last two HO layouts (94-18), I usually ran single unit diesels just for switching purposes.  Otherwise it was 2,3, or 4 unit consists for freight or passenger trains.

But I have to mention the steamers.... I rarely double headed them and much preferred to run them singly.  Have to mention that they were all BLIs w/sound, and I found them very impressive.  My favorite was/is the BLI ATSF 4-8-4, truly a beautiful piece of motive power in all ways!

ENJOY  !

Exactly!the sense of power is what I see when you run multiple power unit lash ups!
