John R. Prentice says that "the Manchester, Bury, Rochdale and Oldham Steam Tramways Co. Ltd. (MBRO, founded c.1883) became the second largest steam tramway operator in Britain with over 90 tram engines, 80 double-deck passenger trailers and 30 miles of routes. Of all these, two-thirds of stock and track were narrow gauge (3ft 6ins), including the section between Bury and Rochdale, through Heywood.
