For another comparison, Moscow Central Diameters system (electric trains traveling from Moscow to nearby small towns) has 4 lines, 137 stations, 188 miles total length. It uses united fare payment system with buses and subway and transfer from a train to the subway is free of charge. Fare is about $1-$3 depending on the route. To be fair, it goes through Moscow at a slow speed and takes an eternity to get anywhere, and its range is limited [1].

Moscow subway [2] has 17 lines and 309 stations. In newer cars, 2 USB-A sockets are available near every seat, ready for robots.
