I will try to explain this as non-technically as possible, so please bear with me (May be two or three posts).
Firstly, there are no real '1-phase' locos in IR. We have DC-DC locos, AC-DC locos and AC-AC locos. The AC-AC locos are what we call '3-phase locos'.

Now, AC current can have many 'phases' (2-phase, 3 phase, 4-phase etc). The common format used for power supply is 3-phase AC power. ( I can explain this if required). Of these 3 phases, only 1 phase is sufficient for operating most common things. You can see this in most household connections. Some houses will have all 3 phases, but some will have only 1 or 2 phases (out of 3).
There are several types of AC motors, most notably 'synchronous motors' and 'induction motors'. Of these, Induction motors are very suitable for railway purpose, as the speed of rotation of the motor can be changed by changing the frequency of the AC voltage.
