Developments responsible for decision by Brit Transport Commission to adopt a-c traction are standardization and universal extension of a-c power supplies in overall grid system, and emergence of static rectifiers by which advantages of a-c may be retained right up to train, yet with d-c available for motors; effect of 50-cycle traction current on signaling and on track circuits.
