GWR 3700 Class 3440 City of Truro

GWR 3700 Class 3440 City of Truro is a 4-4-0 steam locomotive built in 1903 at Swindon Works for the Great Western Railway to a design by George Jackson Churchward. It was partially rebuilt in 1911 and again in 1915 and was renumbered 3717 in 1912. The locomotive is best known for a claimed run from Plymouth to London Paddington in 1904, during which some people believe it became the first to reach 100 miles per hour (160.9 kilometres per hour). That claim is a point of contention and is recorded here as disputed rather than settled, so the locomotive should be read as a candidate for the first steam run at 100 miles per hour and not as an established record holder.
