The town's tram, trolleybus and bus fleet was always painted in crimson and off-white colours, with ornate gold lining out until the outbreak of World War II. The buses were notable in that they never carried exterior advertisements, with the town's crest occupying the space between decks where other bus operators placed adverts; they carried two green lights on the front, to enable the town's ratepayers to see at night which was one of the town's own buses and not one of those of a competitor. At local government reorganisation in April 1974, the Wigan Corporation Transport Department became part of Greater Manchester Transport. The former Corporation tram/bus garage in Melverley Street is still in use by First Greater Manchester.
