I have a MTH R42 subway set I want to run endpoint to endpoint. I need to find out if there is any way that I can make this train automatically reverse when it hits the endpoints. I am new to modelrailroading Please Help!! Thanks in advance.
The easiest is to buy a set that does reverse automatically. These are bumper types. You can buy reverse boards but they require installation knowledge and track detection methods.
I went with a DC engine and a method that works for HO. I made a timer with a relay. At each end I use a diode to stop the engine. The timer reverses the current with a relay. Click reverse in my signatureto view the thread.
