It is economical and universal.
ac motor is nothing but induction motor.So check out for characteristics of induction motors.
AC, 120 Volts.
AC stands for alternating current in physics. It is an electric current that reverses direction at regular intervals, typically used in power distribution and for electric motors.
Electricity having AC current.
It is used to detect very small DC currents only. For AC signals Detectors are used.
Yes, but the DC current generated needs to be turned into AC first.

No ... AC means Alternating Current - DC means Direct Current. DC is used mostly for electronics and for voltages within our vehicles. AC is used for motors and for our household appliances and lamps.
Transperth EMU (Electric Multiple Unit) Traction voltage is at 25KV AC, The current that runs though the train is quite the mystery tho :PHope this answer wasn't too late for you :)
AC induction motors are not always used in trains as traction engines, however they are a popular choice. AC induction motors are very simple and reliable and aside from bearing wear they have no parts that wear out. This is because the power used by the rotating parts is supplied by the magnetism like in a transformer and so there are no slipping brushes. Most train systems actually use a DC supply, then a device called an inverter is used to convert the DC to variable frequency to drive the AC motor and control its speed. When this is done the AC induction motor is a very reliable and flexible engine and even allows energy recovery when the train is breaking.
