30 W1-class trams built between 1925 and 1928. They were a variation on the W-class trams and used a different seating arrangement. The middle of the tram was open like the earlier cable cars and allowed passengers to get on and off the tram quickly. However, in cold and wet weather the openings were only covered by pull down blinds. Passengers were looking for more comfort and these trams were later converted to the W2 design. Four SW2s have been converted back to W1 in preservation. W2/SW2 The W2-class was introduced in 1927 and remained in service until its final withdrawal in mid-1987. The 406-strong class was the backbone of the MMTB's vast fleet during their heyday from the 1940s to 1960s. Most class members had been converted from the earlier W and W1-classes. The trams featured two enclosed saloon areas at either end of the tram and an open "drop-centre" section in the middle. A trademark feature of these vehicles until the 1970s was their uncomfortable wooden bench-style seats, a feature they shared with most other Melbourne trams of that period. Mechanically, they had four under-floor motors powering two sets of the MMTB's "number one" bogies. The driver's controls were made by Westinghouse, Dick Kerr controllers, and Clyde Engineering controllers. The W2-class also had many variant gears within the tram bogies, the spur-geared W2 classes were notable due to their humming sound. Two of the W2-class had their roller blind doors converted to sliding doors and were reclassed SW2. Four W1-class were converted directly to SW2-class. Towards the end of their useful lives, many class members were converted to service (non-passenger) stock such as carborundum rail scrubbers, permanent-way vehicles, railgrinders and breakdown units. A large number of units were also sold to museums and public transport operators in Australia and around the world, with some still running today. From 1978 until 1982 many W2s were painted by well-known Australian Artists as part of the "Transporting Art" program. In 1981 W2 442 was converted for use with the Colonial Tramcar Restaurant, entering service in November 1982. The last W2 to run in regular service in Melbourne ran in December 1987 on route 93 La Trobe Street to Bundoora, although a small number were used well into the early 1990s during extended tram shortages. No.442 was used by the Colonial Tramcar Restaurant until 2006 when it was withdrawn. While the majority
