Minimal amount of wagons for a train

A train is a train, even if it's just the locomotive! If you make one wagons and say it's a train, don't let anyone convince it's not.

In my city, when it's non-rush hour, trams go around with just one wagon, so..

I think it has to have at least 20, half of them AAA. You should consider this when making your first one. Glad I could help. ^_^

For me, the first rule of train club is: wagons have to be private...
