I found this video of possible German origin on You Tube.
Electric powered trolleybuses once operated on the streets of cities like Chicago Illinois, Cleveland Ohio, Johnstown Pennsylvania, Des Moines Iowa and Dallas Texas.
Operating trolleybus layouts in H.O Scale are a bit of a rarity here in the United States, but
somehow have found a well deserved following overseas in Europe.
Seen here is an H.O Scale trolleybus layout in Germany.
