The family of Walker railmotors were a type of 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 twelve 102 hp (80 kW) railcars, six 153 hp (110 kW) railcars with trailers and twelve 280 hp (210 kW) railcars from Walker Brothers in Wigan, England was placed, and this was extended to include a further ten 153 hp railmotors and trailers. The first was delivered in 1948, with new additions to the fleet running through to 1955.[1][2]

Construction[edit]

The power units and controls were shipped out from England and the car bodies built locally by Martin & King in Malvern, with the finished units assembled at Newport Workshops. The van bodies were constructed with composite wood and steel framework, and aluminium sheeting screwed to the frames.

The intended life of the Walker railmotors was only 10 years. However, most remained in service for up to 30 years.

102hp & 153hp[edit]

The final fleet included 13x 102 hp engine/driving units 1-13RM and 16x 153 hp engine/driving units 20-35RM which looked similar; these shared 27x trailing units each mounted on only one bogie, and attached semi-permanently to the associated motor unit, leaving one motor unit of each type spare. The trailing units were not identified normally when in service, but some correspondence notes individual identities No.100 to No.111 (or No.101 to No.112[3]) and No.220 to No.234. This was marked on a small plate on the passenger/driver door of cabs.

The passenger units were all identical with room for 18 1st class and 22 2nd class seated passengers plus 2 tons luggage, except for 100, 104 and 220, which had 18+27 seats and room for only 1.27 tons of luggage; their tare weight was a ton less than the rest of the fleet.

Newsrail April 1982 records the small-van units as "11, 12 and 20", and coupled to 3RM as of 8 June 1976, and 31RM as of 1 January 1977.[4]

280hp[edit]

Separate to the paired units, railmotors 80-92RM consisted of two driving/sitting units, one either side of the power unit that gave its identity to the full consist. Originally, 80-91RM were in service and 92RM was spare without attached driving/passenger units.

One unit in each pair was fitted with seating for 38 1st class passengers, and the other had 56 2nd class passengers, for a total of 94 seats. Each was also capable of holding a single ton of luggage, and it was possible to walk through the centre motor unit via an offset corridor

Unlike the 120 hp and 153 hp variants, the driving/passenger units of the 280 hp series were classed A880-A891 for the 1st class units, and B880-B891 for the 2nd class units. While possible, there's no reason to assume that the sets were broken up or shuffled around, besides the central motor section.

Trailers[edit]

To go with the Walker railmotors, sixteen trailer cars were built. The first were delivered as class RMT, numbers 50 and 51; they were reclassed to MT in 1949, and further deliveres brought the class up to 64MT.

Each was mounted on two bogies with no driving stands, so they required a runaround at terminal stations. Stylistically, they matched the 102 hp and 153 hp railcars, and were a little shorter than the 280 hp type.

Each trailer had capacity for 16 1st, 22 2nd seated passengers and 2 tons of luggage, except 55MT fitted with 38 2nd-class seats instead of a mixture.

Like the motors, these trailers were not fitted with standard couplings so special arrangements had to be made when it was necessary to move one of the trailers with a normal locomotive.

In Service[edit]

The first run was on 15 March 1948, between Heathcote and Wallan on the North Eastern line; this was with 1RM. The first 153hp unit ran from Spencer Street to Daylesford, until that roster was taken by the first of the 280hp units - 80RM - on 6 June 1950.

The railcars soon saw use on the Bendigo-Deniliquin and Ararat-Portland services, and by the time the 91RM was delivered, Mansfield, Wonthaggi, Woomelang and Wangaratta were also being served by the units. The long Glenrowan – Wangaratta section often saw the railcars exceed the 60 miles per hour (97 km/h) speed limit.[5]

Each passenger unit was equipped with adjustable seating, internal heating, non-draught windows, water tanks for drinking or washing, along with ample luggage storage in overhead wire racks. At least when new, the engines did not cause any vibration in the passenger compartments. The lighting system was powered by the then-standard Victorian Railways' 24vDC supply via belt-driven axle generators, with 20-watt globes. Trailer cars were not fitted with their own power supply, instead drawing power via jumper cables from adjacent units; the exceptions being 54 and 56MT, which are thought to have had batteries.[6]

The 280hp railcars were fitted with fluorescent lighting, likely a first for the Victorian Railways.

It has been reported that the 280hp units had provision for multiple unit control, but that this feature was never utilised.[7] As a result, when running in multiple each unit needed to have its own driver, the two communicating through the standard whistle codes used on locomotives.

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 a number of railcars being withdrawn from service during 1978 and 1979. By 1980 only 82RM, 85RM and 91RM remained in service.[5] The last 280 hp Walker railmotor ran on 17 September 1980, with 82RM operating the 08.00 am service from Melbourne to Woodend and return.

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, and was certified for traffic in March 1990.[5]

Liveries[edit]

Each was originally painted in all-over royal blue, with silver roofs, striping and highlighting. When the first of the B class diesels was delivered, the Walkers then in service were repainted with gold replacing the silver. Over time, the roofs were repainted to blue to hide grime, and the logos and striping were made simpler. To improve visibility at level crossings, the cars had thin orange stripes added in the 1950s, followed by a wide orange "dayglo" band over the top of the yellow stripe below window level. Dayglo was designed to look fairly normal at daytime, but to become reflective at night. These stripes were removed from 1968.

A number of internal themes were trialled, with some cars having ivory ceilings and green and brown walls; others were blue ceilings with brown walls. All were fitted with brown leather upholstery seating.

Typical rosters[edit]

By 1963, the Walkers had settled into a pattern with a number of routes.

The 102hp Walkers typically ran between:

  • Morwell - Mirboo North
  • Ararat - Hamilton
  • Swan Hill - Piangil
  • Castlemaine - Maryborough
  • Benalla - Yarrawonga
  • Ballarat - Ararat
  • Nyora - Wonthaggi
  • Horsham - Goroke
  • Kerang - Koondrook
  • Ouyen - Pinaroo and
  • Numurkah - Cobram

The 153hp Walkers typically ran between:

  • Traralgon - Maffra
  • Ballarat - Linton
  • Echuca - Balranald
  • Ararat - Hamilton
  • Frankston - Stony Point
  • Ballarat - Ballan
  • Bendigo - Deniliquin
  • Echuca - Kyabram "School Train", with three trailers.
  • Lilydale - Healesville
  • Melbourne - Seymour
  • Dimboola - Serviceton
  • Bendigo - Cohuna
  • Wallan - Heathcote
  • Lilydale - Warburton and
  • Melbourne - Mansfield

The 280hp Walkers typically ran between:

  • Ararat - Portland
  • Melbourne - Werribee
  • Melbourne - Leongatha
  • Melbourne - Daylesford
  • Melbourne - Woomelang
  • Melbourne - Wonthaggi and
  • Geelong - Ballarat

Some of these rosters required multiple units.

Withdrawal and Scrapping[edit]

35RM with unit no.224 was the first to be scrapped, on Thursday 15th October 1970. Scrapping then continued at a fairly easy pace until 1977, when VicRail decreed that branch lines in general were to be closed, rendering the units without a purpose. As such, 102hp overhauls were stopped, with failed units being held awaiting scrapping instead. The same procedure applied to 153hp and 280hp units from April the next year.

4RM was the last 102hp unit in service, withdrawn in December 1978; it survived longer because its engine unit had been replaced with a General Motors unit at some stage in its life, permitting a 50mph maximum speed and allowing it to closer match the timetables applicable to the higher-horsepower units.

Withdrawals of the larger units accelerated, and by the end of 1979 only 22, 32, 82, 85 and 91RM were still in service. The latter two of that list were withdrawn next; 85RM suffered a collapsed axle bearing, and ran on one engine to Ballarat North Workshops; however its body condition was deemed too poor to be worth repairing, so it continued on to Newport and was stored there. 82RM was the last of the 280hp units to go, after running an 8:00 Melbourne to Woodend and return trip on 17 September 1980.

32RM ran with 56MT through to November 1980, when the engine was withdrawn on account of a much needed overhaul (which was never completed by VicRail). 22RM and 64MT stayed in service, usually running the 9:11am Melbourne to Leongatha and return trip on weekdays, occasionally forming a Sunbury trip or two after arriving back in Melbourne. On Saturdays the unit pair would run on the Werribee shuttles, and occasionally to either Bacchus Marsh or Seymour as railmotor shortages dictated. but eventually, the gearbox failed and the unit was withdrawn following its return from Leongatha on 1 April 1981.

Preservation[edit]

In 1981, two railmotors and a trailer – 32RM, 91RM and 56MT – were scheduled to be transferred to Victor Harbor, the current site of the Steamranger line. 91RM failed on the Ingliston bank and they ended up stored at Ballarat East; at a later point, the three units were purchased by the Central Highlands Tourist Railway (now the Daylesford Spa Country Railway). At the same time, 7RM was being held at Newport for future use on the Castlemaine-Maldon railway; 22RM was static in the Newport railway museum with 85RM held for future addition, and 59MT marked for same but badly vandalised, potentially to be replaced by 64MT. Lastly, 82RM was stored at Wodonga for the Tallangatta railway's proposed tourist services;

It is thought that the passenger units which had been with 29RM and 31RM at time of scrapping, had been sold for use as sheds somewhere in the Victorian countryside.

Units existing to date are:

  • 7RM with No. X – stored Daylesford
  • 22RM with No.225 – Owned by VicTrack, allocated to ARHS Newport Museum, sub-allocated to Yarra Valley Tourist Railway, in service
  • 24RM, possibly with No.228 – Stored in Huon
  • 32RM with No.232 – Under restoration at Daylesford
  • 82RM with No.887A and No.891B – Stored at Daylesford
  • 85RM with Units X, Y – Stored at Moorooduc
  • 91RM with No.880A and No.887B – In service at Daylesford
  • 56MT – stored Daylesford
  • 58MT – stored at Huon
  • 64MT – stored at Huon
