AMIII Broad Gauge

The AMIII Broad Gauge bogie was designed to meet the demands of 25 tonne axle load requirements in Finland.

The design is based on a low profile axle motion bogie with some features that have been uniquely developed for operations in cold climates.

The design allows for passive steering of the wheelsets so that they are able to take up a radial alignment when the bogie travels through track curves. Rubber elements incorporated into the suspension arrangement permit the wheelsetsn to move in a controlled manner relative to the bogie frame whilst maintaining dynamic stability.

The bogie features a two-stage friction damped suspension system, vertical suspension is provided by helical steel coil springs, whilst lateral movements use a “swing link principle”.

The suspension movements are damped in both the vertical and lateral directions by a double chevron wedge system.
