DMU Bogies
Met-Camm Bogies
The drawing (from Met-Camm drawing 906-12) shows a trailer car bogie.
The image shows a bogie under a withdrawn vehicle in 2009 (51500), still in original condition.
The Met-Camm bogies had some distinguishing features - the three vertical strengthening strips in the centre of the frame, there is a flat plate added behind the leaf springs, and the hornguides (either side of each axlebox) are bolted on with all the bolt heads visible.
The second image shows a modified bogie with extra isosceles trapezium shaped plate added to the lower edge of the centre of the bogie frame, and the bolster beam suspension has been altered. This was visually similar to the modifications done to the Manchester-Blackpool Class 104s.
The remaining images are Met-Camm works photos showings bogies under construction and completed. For some there are two versions, matted and un-matted.
Negative DZ 91
Bogies under construction at Saltley Works. In the upper left an underframe can be seen being assembled in a jig.
Negative DZ 130 Un-matted
A power car bogie. The final drive can be seen fitted to the closest axle, the end frame of the bogie lowered for the cardan shaft to be fitted.
Negative DZ 130 Matted
A power car bogie. The short footsteps on the front tell us this will be fitted to the cab end of a vehicle, the other bogie would have longer footsteps for the van.
Negative DZ 131 Un-matted
A power car bogie. The vacuum cylinder can be seen fitted to the front.
Negative DZ 131 Matted
A power car bogie. On the closest axlebox the silver box part of the speedometer.
Negative DZ 132 Un-matted
A trailer car bogie. At this end can be seen the dynamo which is axle driven.
Negative DZ 132 Matted
A trailer car bogie. On trailer vehicles the vacuum cylinders were fitted to the vehicle rather than the bogie.
