The Aerotrain was a streamlined trainset introduced by General Motors Electro-Motive Division in the mid-1950s. Like all of GM's body designs of this mid-century era, this train was first brought to life in GM's Styling Section. Chuck Jordan was in charge of designing the Aerotrain as Chief Designer of Special Projects. It utilized the experimental EMD LWT12 locomotive (U.S. Patent D177,814), coupled to a set of modified GM Truck & Coach Division 40-seat intercity highway bus bodies (U.S. Patent D179,006). The cars each rode on two axles with an air suspension system, which was intended to give a smooth ride, but had the opposite effect.
History
The two Aerotrain demonstrator sets logged over 600,000 miles (970,000 km) and saw service on:
the Atchison, Topeka and Santa Fe Railway;
the New York Central Railroad;
the Pennsylvania Railroad; and
the Union Pacific Railroad.
Starting in February 1956 the Pennsylvania Railroad ran the Pennsy Aerotrain between New York City and Pittsburgh, Pennsylvania, leaving New York at 7:55 a.m.; the schedule was 7 hours 30 minutes each way. From June 1956 to June 1957 it ran between Philadelphia and Pittsburgh.
In 1956 Aerotrain No. 2 was leased as a demonstrator to the New York Central and ran between Cleveland and Chicago.
In March 1956 the Aerotrain made experimental runs for the Atchison, Topeka and Santa Fe Railway in California as a San Diegan between Los Angeles and San Diego. Its use ended because the trainset had to be turned after each trip and it needed helper locomotives on the Sorrento Grade north of San Diego.
Starting December 1956 Union Pacific ran the ex-New York Central Aerotrain as the City of Las Vegas between Los Angeles and Las Vegas. The train was eventually relegated to Chicago commuter service on the Chicago, Rock Island and Pacific Railroad.
GM's "lightweight with a heavyweight future" was introduced at a time when passenger train revenues were declining due to competition from airlines and private automobiles. Though it featured a streamlined design, the Aerotrain failed to capture the public's imagination. The cars, based on GM's bus designs and using an air cushioning system, were rough riding and uncomfortable. The design of the locomotive section made routine maintenance difficult and it was underpowered. Both trainsets were retired in 1966 after a decade of use. The Museum of Transportation in St. Louis, Missouri, and the National Railroad Museum in Green Bay, Wisconsin, each have one of the locomotives and two of the cars.
Disneyland had a scale version of the Aerotrain, known as the Viewliner, from 1957 to 1959 (see below). Since 1958 the Washington Park and Zoo Railway in Portland, Oregon, has operated a scale, diesel-powered replica of the Aerotrain (dubbed the Zooliner) to transport zoo visitors. Idlewild Park in Reno, Nevada, also has a train ride fashioned after the Aerotrain's locomotive.
