Can u explain : what is supply for train (whether a,c or d.c
).I know that supply is 25000v a.c .But there is rumour that
supply is D.C.
And also explain how lights and fans inside the trains are
working ,and what type of motors are used in trains whether
D.C motors or induction motors .If d.c motor, how it gets
supply.If traction motors are used then what are traction
motors and its functions and how it differs from other
motors and also explain about locomotive .
y d.c series motor in train.train wheels r driven by D.C
shunt motor ,at what voltage,and at what speed.
