Amfleet coach car interior, 1970s.

In late 1973, Amtrak ordered the first of an eventual 492 single-level cars, known as Amfleet I, that were based on the design of the popular Metroliner. With tubular bodies and ridged stainless steel fluting, they could reach speeds of up to 125 mph.

The Amfleet cars came in five configurations, including two types of coaches with seating in a 2x2 configuration. One, intended for use on short-distance routes, had 84 seats, while the other, intended for use on long-distance trains, had 60 seats in a more spacious arrangement. Amcoaches weigh in at 106,000 pounds, and early decor incorporated bold color choices such as the red, purple and blue upholstery shown on the seats in this image.

In early 1980, Amtrak ordered an additional 125 Amfleet II coach cars also for use on long-distance overnight routes. They are similar in exterior appearance to their Amfleet I predecessors, but include only one vestibule and were modified on the interior for a more spacious layout.
