America actually several heavy Rail services that aren't just metros, the biggest ones are Amtrak, the LIRR, NJtransit, SEPTA, the T, Metrolink, BART, Metro-North, CTrail and Metra, but others do exist
Oh there's also the VTA, MARC, and ugh Brightline
Oh fuck, that should have said VPRA, which is the Virginia Passenger Rail Authority, I got them mixed up because there are too many fucking acronyms
