Calgary Transit purchased 22 Orion 01.504 buses #282-303 in 1980. They were used on lesser traveled routes where a 35' long bus would be better suited than a 40' bus. The Orion 1 was purchased instead of the T6H-4523N offered by GM because it was cheaper. All of these buses have been retired from service with Calgary Transit. Even 296 which was sold to Cardinal Coach lines and operated on the Airporter as #1610 has been retired from Cardinal. These buses were powered by the Detroit Diesel 6V-53N engine and the Allsion MT-643 transmission.
