The short answer
A friendly primer on lines, interchanges, terminal stations and the symbols you see on a city rail map. The most useful way to understand the network is to look at the route, not just the train name.

What to watch next
Project milestones, new station announcements and timetable changes are the details that turn a national headline into a useful journey. We keep the relevant route pages linked below so you can move from the big picture into the specifics.
