I have a Peter Witt trolley that is NOT a bump and reverse unit. Is there a simple, uncomplicated way to give it or the track it'll run on auto reverse capability? I'll be running it from point a to point b on a continuous stretch of fastrack (not a loop) and I'd like when it reaches the bumper at one end to automatically reverse its direction and travel to the bumper at the other end of the track and so on. This trolley runs conventional with the  normal forward, neutral, reverse operation on a closed loop of track. I'm not electrically savy so prefer the simplest fix. Anyone know of a company that makes a device that could be added to end sections of track and would accomplish what I'm looking to do?

I have used the Z-Stuff DZ-1220 Trolley Stop and Control Announcement System for my Christmas Layout.  To trigger it I using DZ-1205 Sensors (one at each end).  I've had pretty good results with this setup and it has the benefit of the station announcements and bell.  If that seems like overkill it appears that Z-Stuff also makes a DZ-1240 Auto Stop and Reverse Module.  I have no idea how it actually works but I'm sure if you send them an email or call them you can get the answers you need.

 

Good Luck

Not sure if any of them would work right with a williams reverse unit. When power is removed it will resume forward when restarted. A mechanical E unit has memory after power is removed. It could be done I think if there is a button to re orient it when power is restored and stops are not too long. If The E unit is removed and track power is done with DC,it can be done with relays,I think. I do not have one of the trolleys so I am not sure of the nature of the E unit,if it is the same they use on engines.

To be honest, I don't know.  I do know that the Z-Stuff controller allows for several intermediate stops where the trolley continues in the same direction and that only at the end points does it stop, make announcements and then switches directions.  I use it with an Atlas Bump-N-Go (but obviously I'm not using the bump and go bit 

 

Anyway, here is a link to the user/installation manual and I suggest a call to Dennis Zander for more info.

Looked at the PDF, the DZ 1240 Seems like a good product that will work. A nice neat package for $53.

 

Only issue I see with Williams is that when the session is over you can not shut it off on the reverse stop block since the E unit has no memory.

 

I make my own automation out of relays and timers. Could do something similar for about $25, and $20 more if mid stops are desired.
