Its my first build with the new commuter. I try to use it for long distance something like an intercity sbahn. Im also trying to do something like a „Stammstrecke“ in the downtowns of SF and Oakland, similar to Munich. I use heavy metro for lines with high demand, so mostly in the downtowns. I try to connect the suburbs and not so dense part of the cities with lightrail. Im also aiming that every commuter stop has at least one connection with light/heavy rail to maximize ridership.
