You build mass transit systems like you build networks.
Access nodes, hubs and cores. At the access level is a bus, or potentially a tram (not a streetcar). Think last mile. Well, kilometer. But it's probably more than that, but you get the idea. Buses should connect at some point to the trunk route. They should be accessible by walking not more than 1km, ideally a bit less. Stops should be frequent enough to be accessible but not so often as the trip bogs down to an endless stop-start-stop-start.
Trunks are Rail (or light rail), connect at the hubs. Separated right of way, mostly. This allows express running and stops are several km between them (eg, 5km, plus or minus). Fast enough to get going and beat traffic. Ideally they should have some commercial activity "on the door step". Like a major hospital, university, shopping district or commercial district. Not in the middle of a sprawl. Target top speed 100km/h to 160km/h for longer stretches.
Core routes are then high speed rail targets. 20 to 50km apart. Linked to other neighbour cores directly. Target top speed 200 to 200km/h
Occasionally you'll get super "Core", such as state, or national capitals or major urban areas. The target top speed would be 300km/h or more.
The whole lot if of course "Token Ring" and fixed slots. (Cars are more Ethernet)
Of coruse, that's the theory. In reality with have (1) geography and (2) the reality of how land is used now based on potentially hundreds of years of use. Good luck fixing that.
