Commute to Manhattan via Croton-Harmon Amtrak?
My wife and I are taking a look at Croton-on-Hudson, and I'm trying to figure out how our daily commutes to NYC would shape up. I work at 14th St and 8th Ave, making the commute from Grand Central a bit of a pain. I noticed that an Amtrak train runs from the Croton-Harmon station to Penn, which would shave about 10 minutes off my commute.
My question is, are people doing this? I can't find anyone on this forum or others regularly using Amtrak to commute. It also appears that Amtrak doesn't offer a monthly pass for that route, is that correct?
