Electricity can not stay still in the wires, it has to move along the circuit and out of it.
Just like in an ordnary circuit.
Unlike an ordinary circuit however, when there is no trains to take the power then ask- where is all the power going?
To waste thats how.
Simply the power is just not used most of the time.
I think that the only place where electric is really usesful is on suburban lines where there is many trains running all the time.
Hope this helps.

I think your understanding of electricity is flawed.
How much electricity does your kettle use when it is switched off ? There is electricity in the wire.
