A speeder (also known as railway motor car, putt-putt, track-maintenance car, crew car, jigger, trike, quad, trolley or inspection car, and also known as a draisine (although that can also be unpowered) is a maintenance of way motorized vehicle formerly used on railroads around the world by track inspectors and work crews to move quickly to and from work sites. Although it is slow compared to a train or car, it is called speeder because it is faster than a human-powered vehicle such as a handcar. Motorised inspection cars date back to at least 1896, when it was reported that the U.S. Daimler Motor Company created a gasoline-powered rail inspection car capable of 15 mph.

In the 1990s, speeders were replaced with trucks (usually pickup trucks or sport utility vehicles) using flanged wheels that could be lowered for on-rail (called road-rail vehicles or hi-rails for highway-railroad). Speeders are collected by hobbyists, who refurbish them for excursions organized by the North American Railcar Operators Association in the U.S. and Canada and the Australian Society of Section Car Operators, Inc. in Australia.
