The Amtrak long distance lines are a disgrace, kept barely alive. I had a similar experience where my girlfriend at the time wanted to visit me from Albany to Boston but the train took an hour longer than greyhound. I’m not sure we should even count them as a transportation choice.

Amtrak does run some lines where they can afford to upgrade them to “useful”, notably Acela. Travelling from Boston to NYC is fastest and most convenient by train, although weirdly enough flying might be the cheapest option if you include parking costs for the car option
