Build two connected railroad tracks over a road. Build
a depot on the side of the track that is not on the road. Buy
a train and let it go. Get the train on the track over the road
and reverse it a few times to keep the lights on. Then, let the
train go to the end of the track. It will turn around automatically.
Send it to the depot, sell it, and destroy the depot. If done
correctly, the lights will be flashing with no train.
