Abstract

The bogie frame is welded. The axle boxes (10) have extensions (13) and (14) to house two pairs of coaxial coil springs (11) and (12). The springs of each pair are differenct lenths such that only the longer one is effective when the wagon is empty, but both are effective when the wagon is loaded. An adjustable shock absorber is applied to one spring in each axle box. This is arranged so that the centralising damping is the same value as that of the vertical damping. The bogie is more simple and cheaper to manufacture than those of cast steel construction.
