Both sizes are fitted with springs for a comfortable ride and to increase the ability of the riding cars or wagons to remain correctly aligned to the track, even in the case of some track errors.

The 5" gauge comes with 10 springs, and the 71/4" gauge comes with 8 springs.

The side frames and bolster are cast in Grade CB401 Aluminium and are of excellent finish, requiring little work by the builder to assemble.

The wheels are cast iron of high purity with spokes for the 5" gauge and of disk form for the 71/4" gauge.

Axle boxes are cast iron and can be bored for plain bearings to suit wagons, or for SKF needle roller bearings when used as a riding car. The drawings illustrate both methods of construction.
