Region of British Railways in 1948. Now many of the pits and ironworks were declining substantially or closing, and the mineral branches closed with them. The Rosehall branch had already closed in 1930, and the Slamannan line, passing through remote and thinly populated territory, closed in 1949. The Cairnhill line closed in the 1950s. The communities of Airdrie and Coatbridge continued to flourish, enhanced by other economic activity associated with the West of Scotland, but the through line from Airdrie to Bathgate closed to passenger traffic in 1956. A limited goods service continued on the line until l February 1982 but the line then closed completely, except for the short section from Airdrie to Moffat Mills, which remained open for goods traffic; however this was sporadic. The Benhar mines, the branch network based on the Westcraigs to Shotts Iron Works branch, closed in 1963, and the North Monkland section closed the following year, together with the Bathgate to Blackston Junction line. The original line to Kirkintilloch closed in 1965 except for a short section to Leckethall Siding, which continued until 1982. The Ballochney section closed in 1966. Reopening When the Airdrie to Bathgate section closed to goods traffic, a short stub was left at Airdrie to Moffat Mills. Although officially "open" it was in fact dormant for many years. As passenger suburban travel in Greater Glasgow experience a revival, a short extension along this line to a Drumgelloch station, on the eastern margin of Airdrie, was electrified and opened, in 1989. The line onward from Drumgelloch to Bathgate was reopened on 12 December 2010 as an electrified railway with a frequent passenger service between Edinburgh and Glasgow. This proved remarkably successful. Difficult weather prevented immediate opening of all the intermediate stations, and Armadale opened on 4 March 2011, followed by a new Drumgelloch station, further east than the earlier one and close to the former Clarkston station site, on 6 March 2011. Current operations The largest section of the Monkland Railways network now in operation is the line between Coatbridge and Bathgate; it carries (2015) a well-patronised fifteen-minute interval passenger service between Helensburgh and Milngavie, and Edinburgh. The north-south line between Gartsherrie and Whifflet carries freight, and the Gartsherrie to Garnqueen section carries a passenger service to Cumbernauld, the remnant of the earlier anomaly where Caledonian express trains used this North British Railway section. The remainder of the network is
