The network for the system operator is one of the national functions that Network Rail has.

It deals with lots of stuff that's happened to think is really important and you experience every day, but you probably don't really think about, so: what the timetable is how trains access the network; the forward planning that happens about how the Railways should develop; and it also deals with rates, customer information, national passengers and kind of network operations issues.
