DEVELOPMENT OF PASSENGER ELECTRIC
LOCOMOTIVE
Indian Railways have
developed a variant of WAG 9 electric freight locomotive indigenously
for passenger services with the help of technical know-how acquired
in 3-phase traction propulsion technology.
The locomotive
has been classified as WAP 7 and is under service evaluation.
The trials have indicated that the locomotive is capable of providing
higher acceleration.
The development
of this locomotive in service for super fast trains of 22-24 coaches
will reduce journey time by 30-45 minutes.
Meanwhile, introduction
of the state-of-art 3-phase dual voltage traction drive technology
with microprocessor based control system for Electrical Multiple
Units (EMUs) in Mumbai area with regenerative braking feature
has resulted into energy savings of about 30 per cent. In addition,
this stock has also resulted into a better riding comfort. It
has also increased sectional capacity, improved reliability and
reduced maintenance.
