all indian trains run at 25 kv ac. only in mumbai church
gate area d.c system is still in use.
Lights and fans run at 110V DC system through batteries
under the coaches.
Locomotive uses DC series motor, 25KV is stepped down by
transformer and converted to DC by rectifiers inside the
locomotive itself.
Induction motor not used
DC series motors are used as they have high starting torque.
