|Hertford Loop Line|
The Hertford Line (also known colloquially as the Hertford Loop) is a branch of the East Coast Main Line, providing a commuter route to London for Hertford and other Hertfordshire towns and an occasional diversion route for the main line. The line is part of the Network Rail Strategic Route 8, SRS 08.03 and is classified as a London and South East Commuter line.
First Capital Connect operates suburban services along the Hertford Line between London King's Cross or Moorgate, and Letchworth, Stevenage or Hertford North. Occasionally, East Coast, First Hull Trains, Grand Central and other faster First Capital Connect services operate non-stop along the route when diverted off the main section of the East Coast Main Line, due to engineering work. There is a reversing siding to the north of Bowes Park which is occasionally used to turn around East Coast trains heading for the Bounds Green Depot. There are also bay platforms at Hertford North and Gordon Hill, the latter acting as a terminus during peak hours only.
European Rail Traffic Management System trials on the Hertford Line
Network Rail is using Eversholt Rail owned unit 313121 as a test vehicle for ERTMS on the Hertford Line. The plan involved resignalling a 5½ mile section of the double track route to allow existing passenger and freight services to work bi-directionally over the Up Hertford line, freeing the Down line for ERTMS tests and evaluation.
The line was opened in three stages between 1871 and 1924. The first section called the Enfield Branch Railway was developed by the London and York Railway and went from Wood Green to Enfield. In 1898, a plan was approved to extend the line north to Hertford and Stevenage, in order to relieve congestion on the main line without having to widen the Welwyn Viaduct. Work started in 1905 and Cuffley was reached on 4 April 1910. The construction of two major viaducts and the Ponsbourne Tunnel (at 2,648 yards, the longest in the eastern counties of England and the last to be built by traditional methods), combined with World War I shortages of men and materials, delayed the opening of the route to Stevenage until 4 March 1918. Then it was single track and for goods services only. The line finally opened to passengers on 2 June 1924 when a new Hertford North Station was opened. The line was electrified in 1977.
