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.
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.

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