Swing door cars were reasonably narrow. This was to ensure that two opposing trains with open outward swing doors were clear of each other. At certain locations, clearances were tight and there are stories of swing door cars losing doors that accidentally opened. The fleet could be seen running in any arrangement from 1 car, (using one of the double-ended M cars) to 8 cars.

History

The Swing Door trains were converted to electric traction from 1917 to 1924 from steam-hauled passenger cars. The cars the Swing Doors were converted from were 13.7 metre long bogie cars, the majority of cars were built between 1887 and 1893. These cars were extended by two compartments to a total length of 17.4 metres, and then fitted onto new under-frames and bogies. The conversion process was suddenly halted in 1924, with part-completed cars patched up and returned to service with original codes and numbers.

They initially entered service with class codes such as 'ACM' 'BCM', and 'ABCD' indicating both class and type, being rationalised to a simple 'M' (Motor car), 'T' (Trailer car) and 'D' (Driving trailer) code in 1921, with all trailers being made first class, and all motor cars second class.

Fleet

The maximum size of the Swing Door train fleet was:
  • 144 'M' motor cars
  • 6 'CM' parcel motor vans
  • 32 'D' driving trailers
  • 112 'T' or 'BT' trailers ('BT' indicated second class)

Demise
