The GWR 813 Preservation Fund is dedicated to saving the unique ex-Port Talbot Railway & Docks 0-6-0ST locomotive (when it originally carried No 26). Unfortunately 813 is currently undergoing extensive repair work.
They also own a great collection of rolling stock. This is extensive and includes carriages, vans, guards vans and much, much more.
Check out their site for a super gallery of old South Wales railway photographs.
