The Victorian Railways used a variety of former traffic wagons around depots and for specific construction, maintenance and similar tasks. Very few of these vehicles were specially constructed from scratch, often instead recycling components or whole wagon bodies and frames from old vehicles that had been withdrawn from normal service as life-expired or superseded by a better design.

This page covers wagons used for each of the primary tasks, with links back to the source vehicle in their appropriate page category.

1901 NN → VHWA/VZMA As bogie vehicles became more popular, VR decided to expand the concept into freight transport. The ideal choice for experimentation was a little-used, but very important class of wagon, used for ballasting the track but otherwise having little to no use.

As a result, a prototype bogie ballast wagon entered service in 1901, classed NN 1. This was basically a flat wagon with raised sides along the edge, but also a small hopper with its own raised sides in the middle of the floor; this second hopper had drop-doors for increased capacity. Overall the wagon could take of ballast.

NN 1 was tested over a period of six years, and by 1907 it had either been modified to, or replaced by, a new design. This was on a shorter underframe, but with most of the hopper raised above floor level and considerably taller, the new type could take of ballast. This later design was considered more successful, and so construction started on a new batch of wagons to give NN 2 through NN 46. These wagons were shorter again, and the hopper design had changed further with vertical walls from about halfway up rather than the whole of all four sides being angled. However, these wagons could still take of ballast, with about 660 cubic feet of space.

The wagons were operated by being pulled along track at a very low speed, with track workers (gangers) walking alongside and using handwheels to open the discharge doors slung beneath the hoppers.

In 1924 there was a plan to convert all the hoppers to O type wagons for coal traffic, running between Yallourn and Newport Power Station. Wagons 17, 28, 36, 39 and 46 were used as hopper-donors for wagons O 1 through 5, but the project was abandoned before any more wagons could be sacrificed.

During 1950/51, one hundred welded NN hopper wagons were built to a new design. Now able to take , thanks to advancements in construction techniques and the deletion of buffers, the wagons looked similar to their predecessors but with about three-quarters of the above-frame hopper being angled, and the remainder being vertical, rather than half-and-half. These wagons were numbered 46 - 145, repeating the first number from 'NN 46 that had been converted to O 5 a quarter of a century early.

In late 1958 or early 1959 a number of NN hoppers were stencilled "To be returned to Fyansford", because ballast supplies for the Geelong district had changed from Colac to Fyansford.

From 1960 the capacity of the vehicles was raised, by welding the central side-doors shut, and adding "hungry boards" to add about 30 cm to the top of the wagon on all sides. This was applied to most wagons, and a number received new bogies in lieu of the original plateframe style for further increased strength. All wagons numbered from 46 to 138; and 140 to 145 had three strengthening bars added on each end, extending from the top of the old hopper to nearly the end of the underframe. NN 139 had the hungry boards added, but it did not receive the strengthening bars. With this increase in capacity the wagons could now take of ballast.

In 1971 a number were moved across to Standard Gauge - 4, 18, 32, 44, 71, 73 and 139.

In the 1979 recoding the class was recoded to VHWA; from 1987/1988 25 were further recoded to VZMA, not to be confused with Metrail's VZMA class which was then in use for bogie transfers within workshops.

Today, a handful of wagons are still in service, operated by various heritage groups or else leased out to mainline maintenance contractors. Wagons 40, 68, 92 and 126 are held by the Victorian Goldfields Railway in Maldon; 46 is at Moorooduc with the Mornington Railway Preservation Society; 66 and 125 are with the South Gippsland Railway in Korumburra; and 67 and 108 are kept at Seymour with the Seymour Railway Heritage Centre.

1910 QN → VHNA/VZNA From 1910, another type of ballast wagon was constructed. Known as QN from the start and given numbers 1 through 121, the class construction continued until 1926. The wagons were initially dual-purpose, with a small hopper embedded in the centre of the floor, but with raised sides and ends and steel plates across the floor for carriage of rails and other maintenance materials. Rail carrying probably only continued until the 1950s, with the introduction of KR rail-carrying trucks. However, it was difficult to unload the wagons when being used for ballast, because the sections of the floor over the bogies were flat.

The QN series generally ran on plateframe bogies, although wagons 1 and 116 were spotted with cast bogies in the late 1960s.

Correspondence exists indicating that it was intended that later wagons, 92 and above (along with some QR wagons), would be built using underframes recycled from the NN to O conversion project with splices added to increase the length. As this conversion did not happen the wagons were built new, although some in this number range have splices evident in the sideframes.

Most vehicles ran within districts and were stencilled for the loading location, for example wagons captive to the South Gippsland region (such as QN 79) were stencilled "RETURN TO RUBY", and those in the Bendigo region (like QN 43) were marked "RETURN TO MARONG".

QN 31 was fitted with a cement mixer and associated equipment. It appears the vehicle was used for the installation of electrical overhead masts along the suburban routes, and a photo from the late 1930s shows this modification after conversion to autocouplers. By the 1970s it had been converted back to the normal type.

The 1979 recoding for the QN class was VHNA, with about half the class making the switch; 4, 8–12, 14–17, 19, 22, 24, 26, 29, 31, 33–35, 39, 40, 42, 54–56, 59, 61, 63, 67, 69, 71–74, 77, 80, 88, 91, 92, 98–100, 102, 103, 106–109, 111, 114, 116 and 119. Of these, some lasted long enough to be recoded further in 1987 to VZNA; 8, 12, 19, 71 and 107 among them.

Most of the wagons were removed from service with the advent of the VHMY/F wagons (later VZMF). However, there are a number of survivors. Wagons 22 and 79 are held by the Victorian Goldfields Railway in Maldon; 33, 39 and 100 are with the Yarra Valley Tourist Railway in Healesville; and 72 is a static exhibit at the Australian Railway Historical Society museum in Newport.

1959 ON wagons From 1959, 75 of the 15-ton fleet of O wagons were randomly selected for conversion for ballast train use. The vehicles had their butterfly pin-catch doors replaced with handwheel-controlled doors, allowing partial opening to control the rate of ballast discharge from a moving train. Between 1962 and 1968 some of the wagons were returned to the coal fleet, though the changes were not reversed. The remaining ON wagons were used for limestone traffic between Nowa Nowa and Maryvale.

1984 VHMF/Y & VZMF later GHMY, CHMY, CHOY wagons Between 1984 and 1986, thirty of the VHBY briquette wagons had been withdrawn from service and converted to ballast wagons. They were recoded to VHMY 1-30, to replace the ageing NN and QN ballast wagons. The new wagons were pneumatically discharged in lieu of the older system where the ballast doors were controlled by handbrake-style wheels mounted on the side of the wagons; this older method required track staff to walk alongside the train and control the ballast discharge procedure while in motion.

With the new system, the operator could stand on the end-platform and, via a rotating drum mechanism, control both the direction and amount of ballast, anywhere from one side of the rails to the middle or the other side.

An additional 40 new-build wagons were constructed to supplement the class from 1985, with wagon numbers 31 through 60 and 1001-1010 being built new as VHMY. The lower-numbered batch fell into use with the others in the fleet, while the 1000-series wagons were painted in Metropolitan Transit green and used as a block ballast train for the suburban network. The suburban vehicles were later modified with a cage over the operator control stands, to protect crews from overhead wiring, and were marshalled into two five-wagon sets with a green and gold-painted VZDY on either end.Newsrail January 1988 p.24

In 1988 wagons 11, 18, 22, 23, 34, 36–38, 42–45, 49, 52, 54 and 56 were reclassed to VHMF; the remainder went to VZMF in 1989, and the VHMF class was relettered to this between 1990 and 1994. The new code reflected the departmental use for the wagons.

In modern times, the wagons are owned by CFCL Australia and operated under the CHOY code. Between VZMF and current, they have held codes GHMF and CHMF, the G prefix indicating Great Northern Rail Services and the C prefix for CFCLA

Spoil wagons VZOA/F & VZRA In 1978 E1 was recoded to HR115; in 1988 E11 became VZRA110, and around 1990, VOAA-ex-E open wagons 121, 123 and 174 were recoded to VZOF. In 1995, HR115 was recoded to VZOA95.

VZOF121 had its sides cut down to less than half of the normal height.

The VZOF wagons were used to collect waste ballast being spat out by track machine RM74. It is not clear what the purpose of the VZOA and VZRA wagons was.

VZOX In 1997 a random assortment of open wagons were reclassed and allocated to spoil trains, collecting contaminated soil and ballast material removed from pits between platforms and other hard-to-reach areas for transport to disposal sites. It is not known how many were used, but they retained their ex-ELF/ELX/VOBX/VOCX/VOFX numbers. Known members include 7, 177, 212, 291, 344, 367, 372, 1029, 1133, 1146, 1154, 1158 and 1165.

Sleeper wagons VOFY, VZOY & VZSF - Sleeper Discharge Wagons In 1979 the Victorian Railways forwarded two standard ELX underframes from Bendigo to Portec, a manufacturing company in Villawood, Sydney, NSW, to be fitted with automated sleeper discharge equipment based on concepts dating back to the late 1950s. The idea was that sleepers would be loaded into the wagon, and then as a train ran along the track they would be slowly "kicked" out the side into place for future installation. This work was normally done through manual labour, which was expensive and time-consuming. On return to Victoria, the wagons were classed VOFY1 and 2.

Based on photos, it appears that 22 columns of sleepers were loaded into the wagon, and when running a hydraulic plate would push the timber sleepers out the side of the wagon before automatically resetting for the next batch. However, the project was generally considered a failure in practice; Vincent hypothesised that this was because North American sleepers (ties) were cut from softwood in a mill to uniform dimensions, while Victorian sleepers were hardwood, often cut on-site by contractors to minimum dimensions. As a result, no two sleepers were identical, and this made mechanisation difficult.

In March 1989 the wagons were reclassed to VZOY, and then in June 1990 to VZSF. They were stored in Tottenham Yard from then to 1997 and were later transferred to an unknown destination. However, rakes of the similar VZSX wagons were sighted at the North Melbourne Wagon Storage yards in 2010, pending transfer back to Tottenham Yard for scrapping.
