Trolley line?

Talk with the people at Dallee Electronics. They can give you all the various solutions. Pick the one that's right for you.

Another option is an MTH PS2 trolley. I have not tried it, but I'm told they can be programmed to do what you suggest.

Fort Pitt Highrailers had done a Dallee point to point trolley.   Detail said a minimum of 12 ft, though we got it to work at 8 ft, two four foot modules.  Click on the underlined phrase to link detailed instructions.   Any trolley or locomotive (Forward/Neutral/Reverse)  Three position E-unit control.  Bumpers/stops are not required, though a good safety feature. 

Thank you. I'll check out both options.

If the trolley has an e unit then I believe Z Stuff offers an automatic reversing unit.  I use a Pocono Mountain Lines auto reverse board in a similar manner.   Distance is not an issue with either, the reverse sequence is based on activating the relay on the board.  I think the Z stuff board requires isolated rails, the Pocono mountain lines requires isolated center rails, three sections, the two ends where the trolley would reverse and a running section which can be whatever length you desire.   I have an extra one if you decide to go this route.  

The MTH Proto 2 and 3 Trolleys can be programed for point to point (foreword reverse) operation with stops and announcements in between.  

Thanks to all. I'll need to think about this a bit more. There may not be enough clearance for the route I had in mind. It's only at one spot (sort of like a slot car squeeze track) and I might be able to come up with a workaround.

The MTH bumper trolley works well at low speed.
