Edmonton's very first trolleybuses were split between 2 builders, EEC/ AEC, and Leyland. #101-103 were built by English Electric/ Associated Equipment Company while #104-106 were built by Leyland. Both sets of buses had Park Royal bodies. #101-103 arrived in Edmonton in September 1939 in time for the opening of the trolleybus system on September 25, 1939. These buses had 3 axles as opposed to 2 axles like most other Canadian/ American buses. These buses were powered by an English Electric 408 115 HP motor. During their lives, these buses did get a rebuild. #101 lasted the longest, being retired in 1951, while 102 and 103 were retired in November 1950. All were off the property by 1954, and none are known to survive.

	101		#101 posed for photos possibly along the service wire for the trolley coaches to reach the Cromdale Garage. This would be supported by the destination of Car Shops on the front destination sign. The man standing in the door is thought to be Thomas Ferrier. He went on to become superintendent of ETS, and has a garage named after him... the Thomas Ferrier Garage located in South Edmonton.
