I found these devices https://www.amazon.co.uk/gp/product/B0793NYYPZ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 excellent for controlling all aspects of the railway electrics, from lighting to water pumps works great with Alexa too! and can be set to use timers so you can make individual relays turn on/off when you need them.
Nice being able to say "Alexa turn Trains lighting on/off"
