King County Metro 4124 Trolley Bus

I spotted this bus video this morning on You Tube.

While electric powered trolley buses came and went in many
citties in North America and Canada, the city of Seatle
Washington USA luckilly decided to keep theirs going, and
eventually upgrade their system with new high tech electric
powered trolley buses.

An electric trolley bus from Seatle's King County Metro transit
system, is viewed making a runby in downtown Seatle Washington.
