... with PS/2 (5v).
If I'm pulling a heavy train up a steep incline and have a 100% duty cycle (assuming that the motors are PWM controlled), what is the resulting DC voltage that my motor sees? I consulted the all knowing Google and didn't find the answer. I'm hoping one of our resident MTH service techs knows the answer.

I have an idea. If it works, I'll have a double headed 2-8-0 freight train running from a single PS/2 board, for far less $$ than a PS/32 kit.
Using the PS1 2-8-0 that I accidentally bought and an Arduino, it will have simple sounds (startup, idle, flywheel controlled chuff, shutdown). I can even sync the smoke to the chuff. I may even be able to do a brake sound (if the duty cycle drops more than X over Y period of time). I'm going to aim for the 1st 4 sounds and chuff. Braking sounds will be icing on the cake.
I know I will need a front coupler somewhere, but I'm going to wait until the test circuit works before I start "kit-bashing".
If it fails, it will most likely simply not work. If it fails BADLY, I will have another locomotive in need of a PS/32 board. Being that it's a 5v board, it's a gamble that I'm willing to take.
I'll draw up the schematic shortly and post it. BUT I need the original question answered first so I know what I need to design.
