Chicago Transit Authority 1983 Canadian Flyer work bus # WB-2. Chicago Illinois. July 2006., a photo by Eddie from Chicago on Flickr.
I took this photograph back in July of 2006.
Seen here parked underneath a Chicago Transit Authority elevated rapid transit structure near North Clark Street, is a demoted 1983 CTA Flyer of Canada 40 foot transit bus.
These buses were known as the "1983 Flyers" by local Chicago bus fans, and sadly had a short reign in service of approximately 12 to 13 years.
This 1983 Flyer bus, is now working as a maintenance work bus for the CTA, maintaining the transit facilities and infrastructure.
