Abstract
The paper deals with the 600-volt rolling stock designed and built in England to the order of the Toronto Transportation Commission in Canada (since reconstituted as the Toronto Transit Commission), whose new underground electric railway is now in passenger service. The traction equipment is described, together with the arrangements for the collection of power by the trains and its distribution in them. Particular reference is made to the provisions for the safe return of current to the rails. The low-voltage auxiliary equipment is described, and the extensive arrangements for coach heating and ventilation are set out; the electro-pneumatic braking system and door control are also detailed. The descriptions are preceded by a survey of the traffic problems of the city of Toronto and the decisions taken to expedite the movement of its urban passengers. The paper closes with a few comparisons with similar stock elsewhere and gives numerical data in an appendix.
