5239 was built at Swindon in 1924 and has raised frame over the cylinders.
It was based at Neath for all of its working life which lasted until 1963 when it was withdrawn when it was sent to Barry scrapyard where it remained until 1973.
The locomotive was purchased by the Dart Valley Railway and arrived at Newton Abbot in June 1973. Much of the restoration work that was then undertaken was done at Newton Abbot before it was moved to Paignton in June 1976 where 5239 was returned to steam.
5239, which carries the name Goliath, was taken out of service on the Dartmouth Steam Railway at the end of the 2015 season and stored at Churston work.
In October 2017 the locomotive was moved to the East Somerset Railway for a contract overhaul. By early 2018 the locomotive had been dismantled and its frames shotblasted and its boiler moved into the workshop for attention.
By October 2018 the locomotive had been re-wheeled at the East Somerset Railway. It was considered that the overhaul was on schedule to be completed by late 2019 in order that the locomotive was in traffic in 2020.
In June 2019 the East Somerset Railway announced that boiler had passed its hydraulic exam and a fire had been lit in the locomotive as part of the start of steam testing. The boiler was lifted back onto the frames the following month.
The locomotive was returned to the Dartmouth Steam Railway in April 2020.
