Vintage Tomy Train stop and go colour light signal working (compatible Thomas)

Vintage Tomy Train colour light signal and associated stop/go track. The signal has been tested (with batteries - not included) and is working, switching between red and green when the lever for the stop track is moved to make the train stop or let it go. The track piece doesn't have any cracks or splits (as far as I can see) and has an intact red lever.
