of transfer sidings within the factory. After the privatisation of British Rail, RNPF Caerwent like a number of other MOD sites with internal railway sidings, was used as a secure storage area for holding surplus locomotives and rolling stock that might be returned to use. A small number of electric locomotives, particularly in the British Rail Class 86 and British Rail Class 87, were scrapped at RNPF Caerwent. Between 2008 and 2014, the railway tracks were removed but the trackbeds left in situ. A number of unsafe buildings and redundant acid storage facilities have also been removed since 2014. In summer 2022, work began to remove the final stretches of track that remained within the site and on the connecting branch line. The disassembled rails will be transported to the Gwili Railway, a Welsh heritage railway at Carmarthen. The former trackbed is to be converted into a footpath and cycleway. Filming location Scenes from the Hollywood blockbuster Captain America: The First Avenger were filmed on site in October 2010. More recently, Caerwent was used in the television series Top Gear.
