crazy?

1st I would say try and see second thanks was trying to remember the difference between the two versions, should of realize no magna traction during the Korean war years

I think you will be alright. On our modular club I used one 2025 (not a '52 version though)  to pull 24 cars, including several postwar tank cars that don't pull the greatest. The curves are a lot more sweeping on that layout though, so stringlining may be an issue. I would hardly blame the motive power for that though. I also substituted a 6466t for the whistle tender.

As mentioned earlier, try it and find out. Then report back. I would probably start out with one engine and a dozen or so cars, and add cars until the one engine can't do it any longer. Then add the second engine and keep adding cars. That way if a stringline were to occur, it may do less damage than if you started out with the whole train.

Hope this helps,

Not crazy, you mean like this only with a lot more cars?

or this:

First you will need to make a bracket to hold a front coupler mu them together since the 2025 doesn't have one.  OGR published article with scale plans how to do this a few years ago which I followed.

I have successfully pulled about 20 plus post war cars of various types, which was all I had at the time, but don't have a video of it.  If I remember correctly, I still didn't reach the limit on my flat O36 curves fastrack layout and two 2025s from 1947 without magnatraction in the front.

Just experiment and see how many you can do before you get stringlining or massive wheel slip.  Grades is where the 2025 really has issues typically.

I think you will be alright, but not certain.  It has been my impression that the magnatraction does not have a huge effect on level track, but I could be wrong on this.  I've successfully pulled 18 modern style cars behind my 2055, and probably more, but that is the largest number I can remember for certain.  I can not recall right now if the e-unit was locked to do so.  On O54 and O72 curves you should not have any problems, and I've done fine on even O27 just by making sure to place the lightest ((or easiest rolling) cars at the back of the train.  I can not ever recall having the cars string off around a curve on O72.  I have had problems with the couplers releasing on some MPC cars when toward the front of long trains and have had to play with the order of the cars until the ones with the strongest couplers were toward the front.  As others have suggested, I would start with one engine and see just how much it will pull. I would expect two locomotives to actually pull a few more than twice the number of cars as the second contact path will improve traction where a single locomotive begins to slip.  The only caveat to this is that you need to be supplying enough power for both engines to have all they need.  If you're running lighted cars, or a small transformer, you may not have enough power to satisfy the demands of both engines under a high load.  

One last thing to watch out for is that you do not over heat the motors by pulling too much of a load for too long.  I would recommend loading the pair down to see what the maximum number of cars they will pull is, then in normal operation try to run trains only about 75% of that length.  I know the old open frame motors are tough, but I don't see any point in beating them up too much.

Pmilazzo that's exactly what I mean.   Its a kinda custom thin im working on. Pics. Will be added shortly. Which brings me to another point. A couple cars I have are going to be custom. I need to make decals for these, how hard is it to do this? Please let me know

Thanks

While I appreciate the fact that you did NOT use the God-awful term "Lashup" in your post, the use of the term "MU" here isn't quite right either.

Steam locomotives are "double-headed" not mu'd.  

I have the parts to Put the knuckle on the 2nd engine but .lost Davids article.
