2 inch scale Clayton undertype steam wagon - stock code 1660

A well made 2 inch scale, coal-fired Clayton undertype wagon to the Robin Dyer design, as serialised in "Model Engineer".

Silver soldered copper boiler with smokebox superheater. Feed by crank driven mechanical pump and injector. Auxiliary hand pump fitted in water tank behind cab. The mechnical pump delivers through a feed water heater mounted in the cab. Blowdown valve mounted to the front. Firing whilst stationary can be done through the front-mounted firehole door, on the move through the top-mounted door. Whilst designed to run on coal, these wagons are easily converted to gas firing if desired.

Twin cylinder, semi enclosed engine, driving through reduction gears and chain to the rear axle mounted differential. The reduction gearing makes the wagon surprisingly powerful for its size. Mechanical lubricator mounted beneath water tank.

Cab controls for blower, injector steam and water feeds, reversing lever and regulator.

Wheels are rubber tyred, front wheels steered by Ackerman linkage as used in the prototype.

The trailer is of wooden construction on steel chassis, quick detach ball-joint linkage to tractor, working leaf springs.

The Clayton wagon has proved to be a popular model, easy to handle at around 70 pounds yet capable of pulling its adult driver.
