Tom Thumb was the first American-built steam locomotive to operate on a common-carrier railroad. It was designed and constructed by Peter Cooper in 1829 to convince owners of the newly formed Baltimore and Ohio Railroad (B&O) (now CSX) to use steam engines; it was not intended to enter revenue service. It is especially remembered as a participant in a race with a horse-drawn car, which the horse won after Tom Thumb suffered a mechanical failure. (See Relay, Maryland.) However, the demonstration was successful, and the railroad committed to the use of steam locomotion and held trials in the following year for a working engine.^: 11
