A view of the Bangalore City station yard, from left to right:
Rani Chenamma Exp., HHPDEMU, Rajdhani Exp. and SBC - JU Express.
These are the lines furthest away from the main entrance and pf 1.
Pit lines, C&W facilities and diesel refueling points are all
here. |

Having arrived from Secunderabad (SC) on the overnight 7085
express, the Kazipet (KZJ) shed's baldie WDM2C # 14032 waits all
day at the SBC station to haul the return 7086 SBC - SC express in
the evening. |
 |
Krishnarajapuram (KJM) WDM2A # 17437 with the SBC - Tumkur
passenger. In the C&W yard is a spare HHPDEMU trailer
coach. |
 |
The SBC - Hindupur (HUP) HHPDEMU ready to depart at 1845 hrs.
This rake will return to SBC the next morning at 0930 hrs. The rake
consists of two driving power cars (DPC) with 1400 HP diesel
electric power pack at either end and six trailer coaches (TC) in
between. Also available in the DEMU family are unpowered driving
trailer cars (DTC) when you have a four-coach rake with one DPC at
the other end. . |

The cab of the HHPDEMU. From left: the recording speedo with a
digital clock, wiper on/off toggle (with an angled lever) below the
speedo, the signal bell buttons (the guard and the driver
communicate with a bell code like an EMU) on the flat surface below
the wiper toggle, the A9 (train brake) and SA9 (loco brake) levers
and three brake-related gauges, angled throttle lever (this has to
be operated against spring pressure (this is the dead man's lever
— to prevent operation in the case of an incapacitated
driver) and rotated through the eight notches, the shiny post on
which the (now missing) spanner-like 'forward - off - reverse'
lever is fitted, the visual annunciator in front of the throttle
with indications of normal and abnormal conditions, wiper actuator
below the windscreen, switch group for operating all electrical
conditions (including starting multiple engines in a DEMU rake),
the master air reservoir gauge (round black face), loadmeter gauge
(white rectangular face), the motor cutout switch (small rotary
switch on the right corner). The horn is operated by a
foot-operated valve. DEMUs are designed to be worked with a single
operator (no assistant driver). |

The engine room directly behind the driver's cab — The
green Cummins KV 16 prime mover (derated to 1400 HP, V16), the BHEL
traction alternator, exhaust plumbing (silver), air intake (black)
from the radiator room (behind the far side wall), the belt-driven
Elgi air compressor with the shiny can-type air filter and the heat
exchanger and the red piping leading to a hydraulic engine room
ventilation fan set in the roof. Towards the right of this location
(on the other side of the alternator) is a KEC 110 V Alternator
(also belt driven from the prime mover) which is used to charge the
lighting batteries of the HHPDEMU rake. The power car has four
traction motors and the main rectifier is located underfloor. The
snappy acceleration of the HHPDEMU comes from the high
power-to-weight ratio and the electronic governor for the
engine/alternator. The entire rake has a self-leveling pneumatic
suspension. The radiator room contains the side-mounted radiator
screens with two powerful 40" hydraulic radiator vent fans in the
roof. |
