Thereafter, there were yearly August excursions from 1978 until 1981 organised by Bolsover Miners' Welfare when trains of at least nine coaches ran to Scarborough. Another source claims that the last charter from Bolsover Castle was a nine-coach train to via Chesterfield on 15 November 1980 organised by Bolsover Secondary School PTA. The decline of the branch was a case of last in - first out. When the line closed to local passenger traffic in 1930 Glapwell Colliery was still going strong. As its sidings left the passenger line north of Glapwell station and all coal went out northwards, the station was abandoned along with the track southwards through Rowthorn Tunnel almost to Pleasley Colliery West Junction, leaving a short length there as a siding. The abandoned section had been difficult and expensive to work and was simply redundant. After closure the tunnel found two new uses, first as a mushroom farm then, during WW2, as an ammunition store. It has since been filled in. This left the earliest two sections – the Doe Lea line and the Doe Lea extension deviation – running as a dead-end branch from Seymour Junction to Glapwell Colliery. Unofficially at least, the branch became called the Glapwell Branch for a generation of railwaymen, as for the next 44 years that was its terminus. Until the advent of British Rail Class 20 diesels in the early 1960s the characteristic motive power along the branch were the ubiquitous Midland 3F and LMS 4F 0-6-0s hauling the dominant traffic – coal. Coal from Glapwell, Ramcroft, Bolsover and Markham, with a small amount of traffic from Coalite and a smaller amount from Byron Bricks. The line's leisurely routine was interrupted for a few days in August 1952 when the ex-LD&ECR Doe Lea Viaduct, which straddled the Doe Lea Branch a short distance south of Bolsover Castle station, was demolished by the army using explosives. This was filmed and the film later used in a commercial war film, becoming a bridge in war torn France. Ramcroft Colliery closed in 1966 and Glapwell followed in 1974, rendering the line south of Bolsover redundant, though it was not lifted until 1978. Bolsover and Markham Collieries closed in the 1990s and Coalite finally went into receivership in 2004, but it had not provided much traffic for some time.
