[1] The branch line was opened to freight traffic in August 1875 with passenger services starting a year later.
[2] Sharpness station was originally a terminus for the passenger services and was no more than a temporary platform next to the docks.
But in 1879, the Sharpness branch became a through-route with the opening of the Severn Railway Bridge, connecting Sharpness with the Forest of Dean side of the Severn Estuary and enabling through services between Berkeley Road and Lydney Town railway station, some of which ran on to Lydbrook.
Through-services to Lydney on the line ceased abruptly in October 1960 when the Severn Railway Bridge was damaged beyond economic repair in a shipping accident, and Sharpness resumed its earlier status as a branch line terminus.
Passenger services ceased on the branch in November 1964 and goods facilities were withdrawn in January 1966.
