O & K JHA (middle hopper) Foster Yeoman 19391 Late
The O & K JHA hoppers were built by Orenstein & Koppel to coincide with the introduction of the Class 59s in the UK for aggregate haulage by Foster Yeoman. They remain in service to date with Mendip Rail Ltd. A rake of these wagons consist of two outer waggons and a number of inner wagons. The notable feature is that the two outer wagons have screw link couplings and buffers on the outer most edge of the train, whilst the connection between inner wagons is a buckeye style coupling allowing closer coupling and hence an overall reduction in length of the train which was considered an important design aim.
The Dapol model of the O & K JHA Hopper will feature:
End Detail view
Inner and outer versions of the hopper will be produced
a. Inner wagons without buffers and buckeye couplings
b. Outer wagons with Lamp, Sprung Buffers and Standard OO model coupling with NEM pocket at one end, other end without buffers and fitted with buckeye couplings.
Sprung Buffers on outer most wagon end
Close coupling mechanism fitted to both types, capable of operating on minimum of 438mm radius
Accessory pack to contain two versions of interconnecting pipes: a. Loose, unconnected, b. Flexible to connect between adjacent wagons
Working rear lamp on outer most end of the train (DC directional, 6 pin DCC socket for control of flashing lamp)
The models will be finished with high level of detail, which will include many separately added details
