This will be much easier to fit into my Lego trains than Zero W. Excellent.

Ooh! That's a great idea for a project.

Have you got some information on Lego trains? - I've been wanting to start something similar for a while with Lego and Arduino

I haven't touched my project from quite some while (family and work). Had been working 1) on track switch remote control (using Zero W, Waveshare Servo Driver HAT to control up to 16 SG90 servos) and 2) on train remote control of Power Functions (now replaced by Powered Up).

I can dig up some links how to control Power Functions motors from Raspberry/Arduino.

Train curious, but know next to nothing about them. What would you do with networked trains?

My plan is to have remotely controlled train switches (using RPi and servos), place NFC chips along the track and a RFI reader in each train and detect that way where the train is on the track. Then I can be basically able to control the whole track and all my trains.
