In early 2018 the Churchward County Trust announced that they intended to build a new 4-4-0 County class locomotive which would become 3840 County of Montgomery.
The plan is that the locomotive will be assembled at the Gloucestershire Warwickshire Railway.
The Great Western Society is providing a large number of parts for the project including bogie wheels, axleboxes and a suitable 3,500 gallon tender chassis. These will remain owned by the Great Western Society until the fund raising capabilities for the new build have been demonstrated.
It is thought that the locomotive could steam as early as 2028 but 2033 is considered to be a more realistic target date. The overall cost of the project is predicted to be between £1 and £1.5 million.
In July it was announced that an order had been placed with Tata Steel of Wednesfield to produce the frames for the locomotive. The frames were cut in November 2018 which is the first step into creating the locomotive.
The hope is that the basic frames will be assembled in 2019 and achieve a rolling chassis in 2023. The frames will be assembled at Tyseley.
The machining of the main frame plates was completed by Googman Metals of Netherfield, Nottingham in May 2019.
In August 2020 it was reported that the main frames could be completed at Tyseley in October 2020.
In August 2020 an appeal was launched to raise the £175,000 which was estimated to be the cost of completing the locomotive.
In October 2020 it was reported that the Churchward County Trust had ordered the cylinders for the locomotive. They are to be cast by Russell Ductile Castings in Scunthorpe after which the cylinders will go to Roach Precision Engineering of Brierley Hill for machining. The cost of the cylinders is thought to be about £40,000.
There is an agreement in principle for the locom0tive to be based on the Gloucestershire Warwickshire Railway when it is operational.
