Ok, now compare to Greyhound
BOS-ALB is *today* 4:15 (1:05 minutes faster than train, 5 minutes faster than the future train) with ZERO capital expense or operating subsidy on Greyhound from SS to ALB bus terminal.
BOS-SYR could be 7:00 with ZERO capital expense if there was a bus' worth of demand (or a small operating subsidy)
BOS-BUF is about 8 hours of drive time. Still way better than 10:22 on the train.
Virginia, the other great state and adding intrastate rail service, has realized that rail is not the answer to connecting their state to economic opportunity on long-and-thin routes, nor when they could run "for free" on uncongested interstates. And in a move that I'd recommend to MassDOT, Virginia is overlaying its Amtrak network with a really fine set of bus routes (operated by Megabus in state-purchased coaches) that gather demand and move it at 70mph on the interstates (https://virginiabreeze.org/)
BOS-ALB-Beyond won't make economic sense until NY has upgraded ALB-BUF to outperform the NY Thruway.
Busses get stuck in traffic.
Leave South Station on friday at 4.30 and you'd be lucky to be past Worcester by 6.30 then sit in some more traffic at 84/90 then more traffic for the constant repairs because all the traffic means the highway needs to be constantly repaired. Also, you're on a bus.
For me, a big part of this is getting people to switch from cars to shared transit. Busses won't do that.
