The 280hp Walker railmotor were a diesel railcar operated by the Victorian Railways in Australia.

After the Second World War, the Victorian Railways undertook a major rebuilding program known as "Operation Phoenix". One of the first tasks was the upgrading of passenger services on country branch lines, through the replacement of 23 wooden bodied railmotors built in the 1920s, and the withdrawal of steam locomotive hauled mixed trains.

An initial order of six 153hp railcars, twelve 102hp railcars and twelve 280hp railcars from Walker Brothers in Wigan, England was placed, with twelve complete 280hp units built in total, as well as a spare motor unit. [cite web

The first of the 280hp Walkers entered service on 6 June 1950, with 80RM departing Spencer Street for Daylesford. The railcars soon saw use on the Bendigo- Deniliquin and Ararat - Portland services, and by the time the 91RM was delivered Mansfield, Wonthagi, Woomelang and Wangaratta were also being served by the units. The long Glenrowan - Wangaratta section often saw the railcars exceed the convert|60|mph|km/h speed limit.cite journal | year = 1990 | month = July | title = A very brief history of the 280s| author = Barry Fell | journal = Newsrail | publisher = Australian Railway Historical Society (Victorian Division) | pages = pages 200 - 201 ]

In later years the railcars already poor riding qualities had deteriorated, especially due to their light construction . By the late 1970s the Walkers had reached the end of their lives, with mass withdrawals being carried out in 1978 and 1979. By 1980 only 82RM, 85Rm and 91RM remaining in service. The last 280hp Walker railmotor run on 17 September 1980, with 82RM operating the 08.00 am service from Melbourne to Woodend and return. The intended life of the Walker railmotors was only 10 years with most running for up to 30 years.

in 1981 the Central Highlands Tourist Railway (now the Daylesford Spa Country Railway) acquired 91RM, 32RM and 56MT with the transfer being carried out in March 1982. Restoration of 91RM began in January 1987, being certified for traffic in March 1990
