About railway tracks

HI, I have a physics sac tomorrow but I'm kinda confused about railway tracks

I know that there is a current, magnetic field and so there is a force that causes the train to move.

But I'm not sure which component, or what produces the current and the magnetic field in a railway track.

Could anyone help me?? (Diagrams would be really nice.)

I don't know what you're talking about.

There's two scenarios which I think you could be discussing.

1) Current train tracks (like the ones in Melbourne) which have overhead electrical wires - the trains are run on DC electric motors

2) MagLev trains which run by levitating on the track and being "pushed" by magnets.
