Several locomotives have been given the name Great Western. The first was an Iron Duke class broad-gauge locomotive built in 1846, the first locomotive entirely constructed at the company's Swindon locomotive works. This was withdrawn in 1870, but in 1888 a newly built locomotive in the same class was given the same name; this was withdrawn four years later when the broad gauge was taken out of use.[136] A standard-gauge 3031 class locomotive, number 3012, was then given the name.
