Manufacturer description

The O&K JHA hoppers were built by Orenstein & Koppel to coincide with the introduction of the Class 59’s 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 wagons 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.

MODEL
These model O&K JHA Hoppers are highly detailed and will be a great addition to your rolling stock.

FEATURES

• Diecast chassis
• Profiled wheels
• Designed from works drawings
• Sprung Buffers on outer most
• Inner and outer versions of the hopper:
• Inner wagons without buffers and buckeye couplings
• 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
• Close coupling mechanism fitted to both types, capable of operating on minimum of 438mm radius
• Accessory pack to contain two versions of interconnecting pipes:
• Loose, unconnected
• 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 lamp) Flashing
• Finished with high level of detail, which will include many separately added details

MEASUREMENTS

• LENGTH OVER BUFFER 182mm
• WIDTH 33mm
• HEIGHT 48mm

Prototype information

Dapol O & K JHA (end hopper) OO, part number 4F-050-001, is a highly detailed O scale model of the Orenstein & Koppel JHA hopper used by Foster Yeoman for aggregate haulage. The model represents the period of the initial privatisation of British rail freight and is supplied in the Foster Yeoman livery.

The original wagons were built by Orenstein & Koppel between 1988 and 1989 and continue in service with Mendip Rail Ltd. A typical rake consists of two outer wagons with screw‑link couplings and buffers, and a number of inner wagons using buckeye couplings, a design intended to shorten overall train length.

The model features a die‑cast chassis, profiled wheels, and sprung buffers on the outermost wagons. Inner wagons are supplied without buffers and with buckeye couplings, while outer wagons include a lamp, sprung buffers and a standard OO model coupling with an NEM pocket at one end. A close‑coupling mechanism enables operation on a minimum curve radius of 438 mm, and a working rear lamp on the outermost wagon is controlled via a 6‑pin DCC socket.

Key specifications are DCC status DCC 6, power pickup on two of four axles, NEM/Buckeye (inner) and Buckeye & Tension Lock (outer) couplings, bogie wheel arrangement, length over buffers 182 mm, width 33 mm and height 48 mm. The model includes an accessory pack with two versions of inter‑connecting pipes, one loose and one flexible for use between wagons.
