This video is about how to run your Lego train or Tram in a limited space or on a shelf.
It will show how to make the train or tram run in a straight line back and forth automatically.
There are 2 methods: one involving just a timer and the other involving a colour sensor.
You will need the Powered Up app, Powered Up motor, and Powered Up Hub.
For the second method you will need the Powered Up sensor.
For those with the Winter Village Tram you will also need track.
The cheapest way of getting the core components and track is to get the Lego passenger train (when it goes on discount at 3rd party retailers…which it usually often does).
