4930’s long-awaited overhaul began with a move from the Engine House to [[Bridgnorth Loco Works]] on 6 October 2013. In March 2017 the [[Friends of 4930 Hagley Hall | Friends of Hagley Hall]], in partnership with Severn Valley Engineering Services, formulated a detailed programme for completion of the overhaul. This "''2020 Vision''" envisages a return to steam in 2020.<ref>[http://www.4930hagleyhall.org.uk/news/news.html Friends of Hagley Hall News update 7 March 2017 '4930 Our 2020 VISION']</ref>
*As part of the overhaul, 4930 will run with the correct Collett style tender rather than her previous Hawksworth style one, following an exchange with the custodians of [[6990 Witherslack Hall]] on 8 October 2013. In 2017 the new tender tank was delivered for work on restoring the tender to continue. By March 2019 the new tender tank was fitted to the refurbished and rewheeled tender chassis.
*By August 2015 the boiler had been lifted from the frames. Major work on the boiler at Bridgnorth Works was planned to start in June 2017, however on 10 April 2018 it departed from Bridgnorth Works by road for the workshops of Northern Steam Engineering Ltd. at Stockton, where overhaul commenced.
*By September 2016 the cylinder block had been removed and examined. This revealed that the cylinders had been previously patched, and were therefore considered beyond repair. 3D Computer Aided Design work for replacement cylinders lead on 11 June 2018 to newly cast cylinder blocks being delivered to Bridgnorth from Shakespeare Foundry in Preston, Lancashire. In March 2019 these were being maxchined by Harco Engineering.
*The driving wheels were removed from the frames on 14 July 2018, so they could be sent to the South Devon Railway for fitting new tyres.
