A map of the Alexandra Dock (Newport) railway as it was in 1919.
The restricted nature of the 1835 Newport Town Dock led to the development of plans for an additional dock (Alexandra Dock) built on a much larger scale incorporated by an Act of 6 July 1865.
During construction of the dock itself, bulk landfill materials were stored near Ty Trist Colliery in Tredegar, in sidings just off the LNWR line.
