Built 1956 - 60, and based on the LMS design (BR Oyster), itself very similar to a Caledonian Railway plough van.

There are ploughs at each end to spread ballast discharged from hopper wagons, which are lowered when in use, using the large handwheels on the end platforms. Wooden blocks under the ploughs "skate" along the rail head (real ploughs can only be used on plain track). Some vans had their ploughs modified to clear the third rail for use on the Southern Region. Includes moulded coupling bar for use with Hornby/Bachmann couplings.

Livery:

It is difficult to be exact on this.There are for main colour schemes, but not every van received
all the liveries. To illustrate this DB993903 was at Waking still in Bauxite
livery 12/84, so was unlikely to carry the Olive Green livery. Also unclear is
the date at which Black vans were repainted in Bauxite, or if some vans
entered service in the Bauxite livery. To add to this, the 'Dutch' livery of grey
& yellow is rather variable. Lettering is shown in position on the diagrams.
Note that the Western Region continued the GWR practice of allocating vans
to specific depots, e.g. DB993898 'LYDNEY'.
Generally common to all liveries, chassis (not headstock), verandah fittings,
vacuum hoses & buffer heads: BLACK. Handrails, door handles, tail lamp,
plough control wheels & lamp-irons: WHITE. Roof: ASPHALT GREY.
Floor & footsteps: DARK BROWN. Air hose tip, vacuum pipes (not hoses) &
lamp lenses: RED. 'Electrification' flashes are indicated on diagrams by
crosses.
Some Sharks remaining in use in 2003 are painted in EWS livery.
Four carried the "Loadhaul" livery
