The station was situated to the north-east of Six Bells Colliery which was served by a network of sidings which remained in use until 30 November 1980.[8] The line was four-tracked to the south of Six Bells Halt narrowing to two lines going through the station beyond which was a loop serving two small collieries.[9] The 35-lever Cwmnantygroes signal box, which lay to the north, was in use until 11 October 1964.[9] The station was provided with an island platform reached via a footbridge.[10] A private siding for J. Lancaster & Co. Ltd trailed off to the west; this was in use from 1891 to 1980.[10] In 1947, two special trains for National Coal Board staff were running daily between Ebbw Vale and Six Bells.[11] This attracted criticism in the House of Commons on the basis of the costs involved.[11] Passenger services were withdrawn from the station on 30 April 1962.[12][4][3] The line through the station was singled on 3 May 1971.[13] The route was progressively shortened as collieries were closed, with the last section being taken out of use in 1989 after the closure of Six Bells Colliery.[14][15]
To the south of Six Bells Halt, there had been a previous station which served the colliery between July 1897 and July 1902.[16] This was an untimetabled halt for the use of miners.[16]
In 2010 Sewta proposed to reopen the line through Six Bells Halt as part of a scheme which would see a new station at Abertillery with an hourly service to Cardiff.[17] The estimated cost of extending the line to Abertillery was estimated at £16.7m according to Sewta. Part of the trackbed, which is owned by Blaenau Gwent Council, is used as a cycleway and there was thought to be sufficient space for a single track.[18] However, after the scheme was omitted from the Welsh Government's National Transport Plan for funding priorities until 2015, Welsh Transport Minister Carl SargeantAM confirmed that the new station would not be a priority until after 2015.[19]
