@Steve Tyler posted:Well, that's a bit of a tale, but the short version is that I use some fairly hefty low-ohm resistors across the relay to provide a trickle of current when the 'stop' section is depowered, with full current restored after the adjustable delay period. That keeps the trolley's E-unit from cycling, leaving it moving forward when power is restored rather than in neutral (it's a Lionel-style four-direction E-unit).
Hum! I wonder if a capacitor would do the job.
It's a bit fiddly, though -- not enough throttle, and the E-unit cycles; too much, and the trolley creeps forward on the trickle and can sometimes escape the stop section prematurely.
I can imagine. 
BTW, I don't have that issue with the twin 'trolleys' -- the one current trolley has a simple bump-to-reverse action that stays forward until it hits something, and the loco is a Lionel with the E-unit switched off in forward. The trolley on order is another Lionel unit of the same type.
Have you considered MTH bump and go trolleys?
