GWR 3700 Class 3440 City of Truro is a 4-4-0 steam locomotive built in 1903 for the Great Western Railway (GWR) at Swindon Works to a design by George Jackson Churchward. It was partially rebuilt in 1911 and 1915, and renumbered 3717 in 1912. Although it is a point of contention, some believe the locomotive to be the first to attain a speed of 100 miles per hour (160.9 km/h) during a run from Plymouth to London Paddington in 1904.
