These Hudswell-Clarke built locomotives were delivered to the Port Talbot in 1900/01.

They weren't given any major rebuilds under the GWR but were lightly westernised. They were withdrawn in the late 1920s/early 1930s, with some sold into industry, .

One has survived and is a popular and successful locomotive in preservation. In spite of being basically an industrial shunter type she works heritage line trains very capably.
