I dearly love the regional Amtrak train from New York to Boston. Right now I am typing this while riding that train.
You park yourself in the cafe car, get settled in and order a coffee. Then you can sit there and get work done while beautiful New England scenery rolls by for several blissful hours.
It’s basically a kind of a cozy mobile office. Except that at the end of a short work day you end up in Boston.
I highly recommend it.
