Auto Reversing Trolley Track

Bill sent in this question:

“I’m planning a point to point trolley track on my layout, separate from the mainline that would run a DC Bachmann Brill trolley.  I’d like the trolley to reverse direction at each end of the track without my intervention. What would be the easiest way to do this reliably? Thanks in advance.”

    I’m planning on the same thing for my layout since I only have about 6 inches front to back.

    One way is to use Bachmann’s reversing track system.

  • Jack Durninsays:

    I have used a Circuitron AR-1 Auto Reversing module and some photosensors to accomplish this task. Really a simple setup. Just need to adjust the sensor inputs for your ambient lighting.

    You can also cut the rails at both ends and use a resistor to reduce the available voltage and slow the car as it approaches the end of line.

  • Sheldon Clarksays:

    I believe Fleischmann also do an auto reverse module, but I don’t think it makes the vehicle slow to a stop then accelerate away again in a realistic manner.

  • Glenn Fentonsays:

    Check a company called Blocksignaling in the U.K. they have a shuttle that works with DC and also have one thats DCC and is self contained. (no need for a DCC power) I’m using the DCC unit for an elevated subway train with station stops on a loop, but it can also do auto reverse.They ship to the U.S and there prices are very reasonable.
