highlights of the Dual Cab 4500 HP Freight Diesel
locomotive- Vijay
• Vijay, the dual cab freight WDG4D is a trailblazer.
• It is the first...
more... dual cab diesel electric freight locomotive
to be built by Indian Railways.
• The locomotive has been designed on a 21.7 metre
platform to accommodate two cabs and this is about two
meters longer than the single cab version.
• The cabs have full width front view.
• Besides the obvious visibility advantages, the
locomotive also has several features for crew comfort.
• Vijay has been provided with air conditioned cabs. The
AC unit is designed to heat up the cab during winters
while cooling it during summers, thus maintaining a
comfortable ambient for efficient working.
• The loco also has TFT screen based integrated driver
display. This feature which is similar to the one used in
the aero planes allows the operating parameters to be
displayed on a single screen.
• The system also provides alarm levels for the ease of
the crew.
• The display system naturally assists the crew through
fault diagnostics. The system reduces eye fatigue,
improves reliability and improves crew response.
• The locomotive has been provided with an
ergonomically designed control stand and seat. The seat
is based on the excavator design (which needs 360 deg
view and operability) has been provided with movement
on three axis for operational flexibility.
• The locomotive has also been provided with airplane
type task light and automotive type auto wash wipers.
• Vijay has been built around the 4500HP 710 G3B engine
with inverter controlled three phase traction motor drive.
• The inverter control uses the state of the art IGBT
technology. This is the technology being used
worldwide by the leading manufacturers i.e. GE, ABB,
Alsthom etc.
• The locomotive is provided with the latest
Computerised Control Brake system which is the world
standard. The brake system uses the latest in the
electronics and communication to improve response
times and to improve reliability.
• The locomotive has been designed to implement the
Indian Railways’ efforts at increasing the speed of
loaded trains to 100kmph. It can run at 105 kmph and
can be used to haul passenger trains in emergencies.
• The cost of the locomotive is approximately 14.7 crore
Rupees as compared to 14.38 crore Rupees for the single
cab version.
