Revision as of 22:28, 17 March 2017
The basis of this type is a design by the London and South Western Railway, first introduced in 1903. Further builds for BRBritish Rail or British Railways took place in 1954, 1971-1974 and 1980-1982. Apart from the bogies there were only minor changes between the oldest and the newest builds, a testimony to the soundness of the original design. Depending on braking arrangements, wagons were designated YGV Walrus (vacuum braked only), YGH Sealion (dual vacuum/air braked) or YGB Seacow (air braked only but with the addition of a vacuum through pipe). Those with vacuum piping removed were reclassified YGA. The SVRSevern Valley Railway vehicles formed part of the last build of Seacows, Lot number 3966, production of which began at Shildon and was transferred to Ashford.
Featuring a large hopper with slab sides, each with 7 vertical ribs, the type has three discharge chutes, one to the outside of each rail and one in the centre. At each end of the wagon is a control platform with three large handwheels to control each of the chute doors. This last batch present a slightly different appearance as the hopper body was now primarily welded instead of rivetted and the vertical ribs were formed of box rather than U-sections. The wagons are mounted on more modern Y27CS bogies with roller bearings.
Acquisition and use by the SVRSevern Valley Railway
In March 2017 the SVRSevern Valley Railway announced the purchase of six Seacow wagons from DBS Cargo, financed and arranged by a supporter. The greater ballast capacity of the Seacow over the Herring and Dogfish hoppers then in SVRSevern Valley Railway use assists the Permanent Way teams in the annual track relay and ballasting operations. They are air-braked so fit in well with the other 15 similarly fitted 'Rudd' Ballast Wagons.

DBS Cargo locomotive 66068 delivered the Seacows from Bescot to the SVRSevern Valley Railway on 10 March 2017. As of March 2017[update] some work is necessary before SVRSevern Valley Railway use. As delivered from DBS Cargo the vacuum brake fittings were removed or disconnected.
