4141 is a member of the GWR "5101" class, commonly known as a Large Prairie, being 41ft (12.5m) in length and 79.71 tonnes. It is a medium sized tank engine with a 2-6-2T wheel arrangement and was designed for suburban and local passenger services, often seen with GWR and BR suburban coaches.

The class was built between 1903 and 1949, and totalled 209 examples. 4141 was built in Swindon in 1946, and was allocated to Gloucester (Horton Rd) for all of its working life, working on banking duties before latterly working expresses to London.

Thanks to the proximity of Barry scrap yard to the former GWR system, 10 examples were saved for preservation. 4141 was withdrawn in February 1963 and reached Barry in November 1964, being saved for preservation in early 1973. 4141 and its classmates have proved to be ideally sized for use on heritage railways, handling the shorter journey times and typical loads, being economic and reliable performers.
