Does anyone know if its possible to take a train from long island to boston?

Question

i also need the exact train/subway routes please.

Answer 1

Yes.  Take the Long Island Rail Road to Penn Station NYC (the main downtown station).  Go upstairs and take an Amtrak to Boston.  

Amtrak trains are all-reserved, so you'll need to buy a ticket in advance.  (it can be 30 minutes in advance if there are seats.)

Answer 2

Unfortunately no.

The best you can do is take the LIRR to Penn Station.  from there you have to get an Amtrak train (either a Northeast Regional train or Acela Express).

You have to check the Amtrak site:http://www.amtrak.com  for schedules and fares (can vary by train and some trains need reservations).

The trip from Penn Station to Boston will take anywhere 3 1/2 hours to 4 hours 25 minutes (depends on train)

Have a good trip.
