After a successful trial run in Illinois, Amtrak is expanding its Pets Aboard service to certain Northeast Corridor routes. Passengers may bring their cat or small dog with them on most Northeast Regional trains between Boston, Massachusetts, and Norfolk, Virginia, and on Downeaster trains between Boston and Maine. There are a number of restrictions: Reservations are required and there is a limit of five pet reservations per train. There is a limit of one pet per passenger. The pet must be in a carrier and must be able to be placed under the seat. There is a $25 surcharge. The total trip can be no longer than seven hours and the pet must remain confined while on the train. Amtrak’s policy regarding unrestricted travel for service animals remains unchanged.
