Hallen Marsh Junction, near Avonmouth is a location that has changed dramatically in the last few years. In 1987 the signal box controlled a forest of semaphore signals around the junction area, with well over a dozen signals in view here. Unfortunately all this steam age equipment has now been swept away. On 15 August 1987, 55026 (B126) passes the junction with the 17:36 Severn Beach to Bristol Temple Meads service. The lines leading off to the right went to Commonwealth Smelting and ISC Chemicals, while the lines branching off right in the background head towards Filton, and still see freight traffic today. Between the Filton line and the line to Severn Beach can be seen the rail served Chittening Estate.
