Before Covid, I took the MBTA commuter rail to Boston from providence for 5 years Monday-Friday. It takes a lot out of you. Each way was 1.5 hours door to door for me. I took a Lyft to the train station every morning because the parking garage fills up early in the morning, like, my train was 7:15am and the garage would already be filled. I slept a lot both ways but nothing was worse than the train breaking down or a train being out of service so other trains were packed. It’s a doable thing, but it is tough. You have to be ready for unexpected delays and long train rides! Good luck if you decide to do it. Become friends with the conductors and the drivers of the trains, it makes it easier.
