Did the servo have the power to actually switch the track?

It was borderline on some switches. I opened the back of the switches and shaved a tiny bit off the little bump on the rods that push the track underneath. Just enough so that there is still a positive action. Found this works perfectly and the switches can still be used in manual. Used a craft knife.

Hello,

How did you connect the motor arm to the lego piece please?

That's where I'm stuck, excited to get this all together!

I used a hot glue gun to glue a lego technic connector to the servo arm

All connected but base isn't quite clipping to the track, going to have a play with it tomorrow but for now I've recreated it from Lego and used the printed piece to hold the motor in place

Thanks very much!
