A
consortium of Siemens AG and Siemens Ltd (India Transportation Systems division)
has received a contract worth Rs.925 crore from the Mumbai Railway Vikas
Corporation (MRVC) for providing the propulsion system and electrical equipment
for EMU rolling stock, which would be built at the Integral Coach Factory,
Chennai.
The
EMUs will be in operation on both of Mumbai's suburban arterial networks, the
Central and Western Railway. After a competitive bid, the Siemens consortium was
notified of the award of contract to be executed over a period of 48 months.
The
scope involves design, development, manufacture, supply, testing and commission
of the IGBT-based (Insulated Gate Bipolar Transistor) three-phase propulsion
system and equipment, with microprocessor-based controls. These systems will be
suitable for operation in dual voltages – the extant 1,500 V DC system and the
25 kV AC system, which replaces it in the future.
The
systems will be adapted to suit the local climatic conditions and will have a
high level of local value-added content.
