Wrangbrook Junction near Upton in West Yorkshire was a location where two lines branched off the Hull and Barnsley Railway main line from Hull Cannon Street to Cudworth. The first junction led to Denaby and Conisbrough on the South Yorkshire Junction Railway, and after some four chains (80 m) further the Hull & South Yorkshire Extension Railway to Wath diverged.
Originally three signal boxes controlled the junctions: "Wrangbrook North" on the south side of the main line by the Denaby branch; "Wrangbrook South" on the west side of the Denaby branch and "Wrangbrook West" on the west side of the Wath branch. In 1934 South and West boxes were closed and control passed to North box which was renamed "Wrangbrook Junction".
