the busy freight artery between and the Port of Immingham. West of Ulceby the line is double as far as Oxmarsh Crossing (near New Holland), reverting to single for the final to the terminus at Barton. This section has several manual signal boxes with semaphore signalling and manned & gated level crossings in operation. Network Rail planned to re-signal the line in 2015–16, with control passing to the York Rail Operating Centre – the level crossings on the line were automated and the existing signal box at Ulceby Junction abolished (those at Goxhill, Barrow Road and Oxmarsh Crossing remain). History The to section of the line follows the Great Grimsby and Sheffield Junction Railway, opened in 1848. This subsequently became part of the Manchester, Sheffield and Lincolnshire Railway and eventually the London and North Eastern Railway at the 1923 Grouping. The line was extended to Cleethorpes by the MS&LR in 1863, with a branch from Goxhill to the docks at Immingham added in 1911. The line was particularly busy during the Second World War, as it served Royal Air Force airfields at Goxhill and Killingholme in addition to the various industrial installations in the area. The line was twice proposed for closure in the 1960s (in 1963 and again four years later), but was reprieved on each occasion (though the Goxhill to Immingham Line did close in June 1963). Prior to the opening of the Humber Bridge in June 1981, passenger services ran via where they connected with the Humber Ferry service across the Humber to Corporation Pier in Hull but after the bridge was commissioned the ferry service was withdrawn and a new chord line and replacement station provided at New Holland to allow trains to run directly to and from Barton. Since then, the connection to and from Hull has been provided by Stagecoach in Lincolnshire bus over the bridge and now operates out of Hull Paragon Interchange. The service ran hourly until the spring of 1990, but was cut to the current two-hourly pattern at that year's timetable change by British Rail due to unreliability and a shortage of rolling stock. The winter Sunday service also suffered the same fate in 1999 following the abolition of Humberside County Council and subsequent withdrawal of funding by the replacement unitary authorities.
