4110 was built at Swindon in 1936 and initially allocated in October of that year to Severn Tunnel Junction to undertake tunnel banking duties. Two months later it was moved to the Wolverhampton district where it stayed for most of the next 26 years. It operated on the intensive local passenger services from Birmingham Snow Hill and Moor Street stations to Leamington Spa, Stratford upon Avon and Warwickshire in general. In March 1942 until April 1943 it was based at Birkenhead before returning to the West Midlands area until 1962 when it was deployed at Taunton on the branch line to Minehead which is now the West Somerset Railway. It went briefly to Swindon and then on to Neath in July 1963 where it worked the Vale of Neath line to Pontypool Road until its last day of passenger services in June 1964. It was withdrawn in June 1965 during the conversion from steam to diesel haulage, having run over 730,000 miles in mainline service. It was sold for scrap to Woodham Brothers at Barry and entered the scrapyard in August 1965. It remained there until May 1979 following its purchase for preservation by the Great Western Preservation Group at Southall Railway Centre. It was the 100th locomotive to leave the Barry scrapyard. 4110 then moved to the Birmingham Railway Museum at Tyseley for contract restoration. Only a partial amount of restoration was completed before the owners decided to put the engine up for sale in order to release funds for the completion of work on 5700 class engine 9682.

The West Somerset Railway put in a competitive tender and bought 4110 in 2015 and the locomotive was then moved to Minehead in June 2015. In 2016 it was estimated that it would take three to five years once the funds and resources to undertake the work were available. The plan was to return it to traffic in 2022. With no work having been done on the locomotive by May 2018 consideration was being given by the West Somerset Railway to a possible sale of the locomotive. Any sale would be conditional on the locomotive being hired back to the WSR once it was restored. It was later announced that the locomotive had been sold to the Paignton and Dartmouth Railway as this was the best bid and the WSR needed the funds. The locomotive was moved to the Dartmouth Steam Railway in February 2019. In September 2019 the East Somerset Railway completed a deal with the Dartmouth Steam Railway to restore the locomotive. which would then operate on the ESR for the first 3 years before being returned to the DSR. The locomotive moved to ESR at Cranmore in January 2020 and restoration work was planned to start straight away. The boiler was lifted off the frames in February 2020 following the removal of the tanks, cab and bunker. Unfortunately soon after this, the Covid pandemic hit and all work in the workshop had to pause. As soon as restrictions were eased, the team had safe procedures in place to enable the restoration to continue. The boiler had a fair amount of new steel platework replaced along with hundreds of stays and rivets. A new set of boiler tubes and flues were installed before the boiler could be refilled with water ready for testing. Whilst this boiler work was going on, brand new tanks and a new bunker were riveted and welded together. Being a survivor from Barry Scrapyard, the loco no longer had any copper pipes or bronze fittings so everything had to be made new. The frames, wheels, motion and axleboxes were all completely stripped down to their individual parts, cleaned, inspected, repaired or made new as required before reassembly. In August 2022 a fire was lit in the boiler of the locomotive for the first time since June 1965. In March 2023, 4110 returned to traffic and will be hauling the passenger service at the East Somerset Railway until 2026.
