The station was built by the Caledonian Railway and opened on 7 August 1848 on their line from Gartsherrie to Greenhill on the Scottish Central Railway. The line gave the Caledonian access to central & north eastern Scotland from Glasgow and its main line from, but the station at Cumbernauld wasn't a commercial success as the village it served wasn't particularly large; and so it closed after just one year of operation. It was eventually reopened in 1870 to be served by local passenger services from Glasgow Buchanan Street on the lines toward Falkirk & Stirling. When planning the new town in the 1950s, there was some consideration made to siting the town centre near the current railway station rather than on the hill top. The railway station in this scheme would then have been moved to the Luggie and Shank valley near the A73, beyond Lenziemill and Blairlinn. However, it wasn't until the after the building of the new town started that the area's population began to expand significantly, and usage of the station increased. This also ensured that the station avoided the Beeching Axe in the early 1960s, even though it wasn't particularly well sited for many of the newly built residential developments. The line did though lose its direct link with the city after the closure to passengers of the Buchanan Street terminus in November 1966. The diversion of all main line expresses and the remaining local routes into Queen Street left the station without any trains serving it, and so a replacement service had to be introduced. This consisted of a DMU shuttle along the old main line into Glasgow, which was still operational as far as the works at St Rollox; however, just east of there they were re-routed onto the former Edinburgh and Glasgow Railway's Sighthill Branch to Cowlairs, which they used as far as. Trains terminated there, with passengers having to change onto North Clyde Line electric services over the former City of Glasgow Union Railway branch to and Queen Street Low Level. Regular local services southwards towards and had also ceased by this time, although a limited number of longer distance trains continued to call there - notably the London Euston to Clansman & Royal Highlander expresses from the early 1970s onwards. Through running to Queen Street High Level was eventually introduced in 1989, and since then several intermediate local stations along the line have reopened with backing from the Strathclyde Passenger Transport Executive. Services both northwards to and southwards to Motherwell have also been reintroduced, whilst the opening of the Cowlairs Chord in 1993 meant that services could now proceed directly to Queen Street without having to reverse alongside the depot at Eastfield as before. The lines to Glasgow & Coatbridge have been electrified, with electric operation beginning in the spring of 2014. This has seen service frequencies on the Glasgow line increased to three per hour, and through running on electric services to the west end of Glasgow via the North Clyde Line through Queen Street Low Level. The station building is also undergoing major refurbishment as part of this work, with a new modular structure opened in July that year. Further electrification northwards to Greenhill Junction is due for completion in 2018, which will coincide with a further planned timetable recast that will see the existing service to Falkirk doubled to two trains per hour and extended through to Edinburgh Waverley via. This will see the town given direct links to the Scottish capital for the first time, as well as upping the Glasgow Queen Street service frequency to four trains per hour. The timetable upgrade & infrastructure work is being funded by Transport Scotland.

Signalling
Cumbernauld signal box, which had 35 levers, was located to the north of the station, on the east side of the line. Latterly it worked by Absolute Block to Greenfoot S.B. and by Track Circuit Block to Greenhill Junction S.B. Its primary function was to operate the crossover and reversing siding used by services that terminated & started back from here. This is still in use today. Cumbernauld signal box closed on 3 May 1999, when the line was resignalled with colour light signals controlled from Cowlairs Signalling Centre.
