A toy train set controller
I love playing with toy trains. I always have enjoyed that.
I've had train sets that didn't have engines and some that did.
When a train set has an engine, what else is needed? (Let them
answer.) To make the electric train work, you have to have a
controller attached to it. Otherwise the train will not run -- no
matter how powerful the engines are. The controller is the main
thing. With it, any train engine will run. You can even have
several engines operating on the set at the same time. But you
must have a controller.
