Funicular railway power question

The Natural Philosopher has brought this to us :
It is three phase and the rail is one phase and is earthed.
Phases are only phased with respect to each other, they dont care about their
relationship with 'earth'.
I see how that would work now. I had in mind star, with the centre
point grounded - a delta output transformer with one point to ground
would do it.
Oh well,Im glad someone does. ;-) Our physics classes never progressed to
three phase power when I was at school and Ive never had a need to
understand it in any depth (or at all really) since then.
