The FOREST OF DEAN (or Bullo Pill) Railway, commenced on the River Severn at Bullo Pill, and ran in a westerly direction passing through a tunnel under Haie Hill. This tunnel, 1100 yards in length, was of considerable length for the period of its construction, and employed a primitive system of staff working to prevent the risk of two trains of waggons meeting in the tunnel. The "staff" was a tree branch which was carried through the tunnel by the driver. At Upper Soudley, beyond the tunnel, the tramroad continued northwards through Cinderford to its termination at Churchway Engine (6¾m from Bullo Pill) where it made an “end-on" connection with a Branch of the Severn & Wye Railway from Miry Stock. With the exception of a realignment at Lower Soudley, the route of the tramroad was absorbed into the Great Western Railway as far as Cinderford Station, but beyond this point the route remained undisturbed.
Opened 1809. Track: plateway, 3' 6" gauge (local tradition is that the Aylesford Ford branch used wooden edge-rails on stone sleepers). Engineer: John Hodgkinson. Owner of the main line: Bullo Pill Railway Co., later Forest of Dean Railway (1826), South Wales Railway (1849). The branches were mostly privately owned. Traffic: coal, ironstone, limestone, timber, etc. Closed and absorbed into parts of a modern railway 1849.
