[1] The attraction commenced operation on June 10, 1957 and was billed by Disneyland as "the fastest miniature train in the world.

"[2] Two separate trains, designed by Disney Imagineer Bob Gurr and built as scale replicas of General Motors' futuristic Aerotrain,[3] traveled along a dog-bone track circuit (rail line with a turnaround loop at each end) through parts of Tomorrowland and Fantasyland.

Motive power for each train consisted of an integral head-end unit driven by an Oldsmobile "Rocket" V8 gasoline engine, mated to a Jeep transfer case powering drive-shafts to both the front and rear wheel trucks.

Two 1954 Oldsmobile 88 2-door coupes furnished the windscreen, doors and instrument console for each of the two 5,000-pound (2,270 kg) locomotives.

[4] The Disneyland Alweg Monorail System ultimately took the place of the Viewliner in June 1959, thereby making it one of the shortest-lived rides in the park's history.
