HO/OO Guage - back and forth on a single track.

[Skyedriver]

Keep having an idea to build a model layout in my impending retirement. Is there a SIMPLE way of setting up a single line of track and having a train running back and forth along it without having to keep switching it myself?

I believe this company produces a solution. Search for the shuttle unit. https://www.heathcote-electronics.co.uk/index.htm

Excellent, that's exactly what I'll be looking for. Thanks very much for your help
Love the idea of auto level crossings as well

What you are after is often referred to as a "shuttle module".

Plenty about of varying complexity and cost.
