Do guerrilla rail, figure out the nearest land contiguous place with a smart grid, and the nearest place with coherent train signalling. if their system isnt shit, adopt the standard. If it is shit, look up whatever the Japanese are using and rip off their shit. Block by block. Just appropriate a traffic lane, say the outside one.

Its not the best way, but I do genuinely think people could fund construction and maintenance of rail lines on their streets. Making them IT and electrical arteries as well (you're already running communication and high voltage lines, possibly small wireless solar setups for signal redundancy) makes sense. Get rural broadband and really good fucking economical transit.

I wish there were a community of extremely obsessive online rail nerds that could be tapped to plan something like this, down to the level of a proper network (with like the tiny tolerances you get in modern rails), so we could just, like, look up our blocks and order the necessary parts off a list and start building.
