Model Railroading > Coupling on Tender?Date: 11/10/22 12:30 Coupling on Tender? Author: wabash2800 I won't be doing this for a while, but I have situation where I have a brass steam loco with passenger cars that has to make a backup move (partly up a grade around a curve) with about 6 cars to get to a station. I'm quite sure with the usual draw-bar set-up, the tender will derail. If I can keep the wiring, I think I might try using a Kadee coupler btw the tender and loco. I think I could clip the trip pins, and painted black, the couplers should be inconspicuous.
Has anyone tried that or another solution? It would seem a similar situation would occur with a brass steam loco backing a large cut of cars in a yard, for example. Victor B. Edited 3 time(s).

You could add some more weight to the tender to keep it from being shoved off the rail.

The drawbar is the problem. Victor B. Date: 11/10/22 15:00 Re: Coupling on Tender? Author: grahamline Are there alternate holes in the drawbar that will let you experiment with the gap between the locomotive and tender?
Date: 11/10/22 15:42 Re: Coupling on Tender? Author: wabash2800 Yes I have tried that, weight on the steam loco's tender running backwards is no good.

Couplers will cause even more lateral forces on the tender making a derailment more likely than a drawbar. I would suggest just testing the scenerio using the drawbar to see if it really is an issue or not. Ted Curphey Ontario, OR Date: 11/10/22 18:02 Re: Coupling on Tender? Author: tomstp I back a long train up a 2 % grade and don't derail anything. Check the wheel gauge of the tender truck you expect to derail.

If the trucks are mounted correctly and are "square" and the wheels are in gauge it doesn't matter when they were built. I would suggest replacing the original trucks with something newer that you know will be "square". Date: 11/12/22 06:35 Re: Coupling on Tender? Author: LarryDoyle Try a longer drawbar attached to the tender floor closer to the truck centerpin.
