We all know Amtrak along the NEC regularly hits well over 100 mph but who is next after them in terms of average speed? I’m a commuter on NJ transit’s service along the NEC and those trains regularly do 90-100 MPH. Is this service the answer to my question or are there other passenger rail routes in the United States (excluding Amtrak) where the top speeds are comparable (or greater) than that? Apologies if this has been asked already.
