Interior of the Western America Railroad Museum, showing two restored maintenance cars. The yellow one is a hand-pumped track inspection car, c. 1900, restored by Robert Clayton and Jim Hays in 1999-2000.
The brown one behind it is a Fairmont Speeder gas engine track inspection car, which were manufactured in Illinois from 1911 through the 1970's. The motor car served out its last years on the railroad as the Ripley District motor car out of Blythe, California. It was purchased by Mr. Michael Gross, the actor from Family Ties, as part of a multiple purchase and given to Mr. Bob Crooks of Barstow, who later donated it to WARM.
By 1980's these track cars were eliminated with the introduction of the high rail. Here is a link to the history of the rail motor car.
