The Hastings line is a secondary railway line in Kent and East Sussex, England, linking Hastings with the main town of Tunbridge Wells, and from there into London via Tonbridge and Sevenoaks. Although primarily carrying passengers, the railway serves a gypsum mine which is a source of freight traffic. Southeastern operates passenger trains on the line. The railway was constructed by the South Eastern Railway in the early 1850s across the difficult terrain of the High Weald. Supervision of the building of the line was lax, enabling contractors to skimp on the lining of the tunnels. These deficiencies showed up after the railway had opened. Rectifications led to a restricted loading gauge along the line, requiring the use of dedicated rolling stock. Served by steam locomotives from opening until the late 1950s, passenger services were then taken over by a fleet of diesel-electric multiple units built to the line's loading gauge. Diesel locomotives handled freight, also built to fit the loading gauge. The diesel-electric multiple units served on the line until 1986, when the line was electrified and the most severely affected tunnels were reduced from double track to single.
