The first Amtrak train was a Clocker that left New York City for Philadelphia shortly after midnight on May 1, 1971. The Rail Passenger Service Act of 1970 provided Amtrak with rights on host railroads and gave it preference over freight transportation. The Amfleet I train car was modeled on the Metroliner, a train car used between Washington and New York. The first train, Train 421, runs from Chicago to San Antonio, Texas, where, after a layover, passengers transfer to Train 422—the Sunset Limited—for the remainder. Amtrak took over America’s last private passenger train service in 1983.
