AFAIK its done by a timetable system - not by simply picking up a train id
at the trackside and setting the route accordingly.

Back in the 1960s the Northern Line was using automatic route setting
equipment. Used a giant pianola type roll with punched holes.

Thats nice. And that is the same as picking up the id from a train on the
track, how exactly?

The way I see it if the giant piano wants to send train A to Barnet and train
B to edgware but the trains arrive in the order B - A , then its screwed.

That's why you work to a timetable.

Face - palm.

We're going in circles here. Never mind.
