Images of various components of WDM2 shot at Krishnarajapuram loco shed.
Conventional type of control stand of WDM2 with the driver sitting
on the right hand side. The lever with white handle is the main
throttle with 8 notches.
The newer desk type of control stand introduced on newer WDM2c's
with the driver sitting on the left hand side. Throttle here is the
wheel in the middle like that of an electric locomotive controls.
The other half of the desk type of control stand. The large white
dial is the speedometer. It is said that this desk type of control stand is
very much disliked by many drivers because of limited leg room, as you can
see in this and the previous photos.
Turbo charger of a WDM2c is the red colored item seen here just below
the exhaust stack. Turbo charger is basically a turbine powered by the
residual energy of the exhaust gases from the engine. The turbine in turn
runs a compressor which compresses the intake air, thus providing more oxygen
for combustion. As a result more power can be extracted from the same engine block.
This is the main dynamo mated to the prime mover which produces the
DC current to power the traction motors.
An open Dynamo with the commutators visible.
This is the expressor(Combined compressor and exhauster) unit which
produces the vacuum for the train brakes as well as compressed air.
A bunch of WDM2 driving wheel sets. The pinion gear on the traction
motor shaft will mesh with the gear visible on the axle here.
