An ″Overseas″ significantly revised variation of this chassis with left-hand steering was also developed to accommodate a single-deck 32 ft. (length) x 8 ft. 3 in. (width) body for seating up to 40 passengers with front entrance and central exit. The chassis had a special wide track and a dropped frame member to permit a ″pay-as-you-enter″ entrance platform in front of the front wheel. A new feature was that all the contactor gear and resistances were mounted at the rear of the chassis. Several chassis of this 664T Overseas type were supplied for service in Montreal, becoming the first trolleybuses put into operation in Canada.Associated Equipment Company / English Electric Company Trolley Buses brochure No. 215.11.37 / No. T69
