I speculate a root cause is freight trains, and all the same abuses that prevent trains passenger rail from being useful. lack of infrastructure investment causing slowness, ever longer trains causing slowness, inadequate sidings causing blocked intersections, out of repair tracks causing slowness and signals cause long delays blocking intersections

Or at least I’ve never seen anyone do that nor know anyone who’d admit to it, but we only have commuter rail so there will be a train but the gates will be up in a minute. no reason to be impatient or do something stupid
