The Great Northern Route (previously known as the Great Northern Electrics) is the name of the suburban rail services run on the southern end of Britain's East Coast Main Line and associated branches. Services operate to or from London King's Cross and Moorgate in London. Destinations include Hertford North, Welwyn Garden City, Stevenage, Peterborough, Cambridge and King's Lynn. Services run through parts of Greater London, Hertfordshire, Bedfordshire, Cambridgeshire and Norfolk.

The route forms a major commuter route into London from Hertfordshire, Cambridgeshire and eastern Bedfordshire; ridership has grown rapidly over recent years. In 2009 rolling stock was transferred from other lines to allow additional services and longer trains to be run. By 2018 the line will be connected with the Thameslink route via a junction just south of the High Speed 1 bridge, north of Kings Cross, to allow through services to south of London.

Route

The network consists of all local and semi-fast services on these lines:

Additionally, the main service on the Fen Line is provided as part of the route. All services are electric.

At privatisation the services became part of West Anglia Great Northern, becoming their sole route in 2004 when the West Anglia services were transferred to 'one'. In April 2006 the services became the responsibility of First Capital Connect. When the Thameslink Programme is completed in 2018, many of these services will become part of the Thameslink network, running through central London to destinations south of the River Thames. In September 2014, the Department for Transport transferred the new Thameslink, Southern and Great Northern franchise to Govia Thameslink Railway.[1]

History

St Albans — a bridge (opened in 1868) carrying the Midland Railway over Hatfield and St Albans Railway (closed in 1964), a branch of the Great Northern Line. National Cycle Network road No 61.

The term Great Northern is related to the Great Northern Railway, the original builders of the line.

The July 1922 Bradshaw's Railway Guide[3] contains a typical rail service on the Cambridge Line as follows:

Six stopping and two (three on Saturday) Semi-fast services to Cambridge (Monday to Saturday) - One Sunday stopping service to Cambridge with two back. The fastest service taking about 1hr30 to travel from London King's Cross to Cambridge.

An additional two (three on Wednesday) services reached Royston (Monday to Saturday) - one additional service reaching Royston on Sunday.

An additional seven services reached Baldock (Monday to Saturday)

An additional three services reached Letchworth (Monday to Saturday), the last service running just after midnight Thursday morning.

Since the 1960s, Great Northern has been used to describe the suburban part of the East Coast Main Line, south of Peterborough and south of Royston. The Great Northern Railway proposed electrification of part of the line in 1903, but it was not until 1971 that a scheme to electrify the line from London King's Cross and Moorgate was authorised.[4]

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

The Inner Suburban Lines to Welwyn Garden City and Hertford North were electrified in 1976[4] with Class 313 EMUs. In 1978[4] the electrification was complete to Royston with Class 312 EMUs providing the service. The route was then promoted as the Great Northern Electrics.[4] The route between Hertford and Langley Junction, south of Stevenage, was also electrified but not regularly used by electric trains until 1979 when one Moorgate-Hertford service per hour was extended to Letchworth; prior to this diesel multiple units provided an infrequent service over this route, running between Hertford and Huntingdon/Peterborough. From 1979 until 1987 DMUs provided the service between Hitchin and Huntingdon/Peterborough. DMUs also provided a shuttle service between Royston and Cambridge between 1978 and 1988, connecting with the electric trains and replacing the former through Cambridge buffet expresses between Kings Cross and the university city.

In 1982 Watton-at-Stone station was reopened between Hertford and Stevenage. A new station also opened at Welham Green in 1986.

With the electrification of the East Coast Main Line electric services could be extended to Peterborough and the Outer Suburban Service was changed from Class 312 to Class 317, some of which were cascaded from the newly created Thameslink route, with the remainder newly built.

In 1984[5]

the decision to electrify the line between Royston and Shepreth Branch Junction with the West Anglia Main Line north of Shelford allowed the reinstatement of through services to Cambridge from London King's Cross via the East Coast Main Line, resulting in faster journey times than from Liverpool Street via the West Anglia Main Line. This electrification was completed in 1988.

Later the track between these points was also upgraded with welded joint track instead of the jointed track that had existed, and line speeds were raised to 90 mph.

Rapid growth on the route, especially on the Cambridge Line resulted in consultation on a new service pattern,[6] which was then implemented at the timetable change in Spring 2009. During the peak hours, the route is now saturated and can support no further service improvements.

Hitchin Flyover

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

Together with the Digswell Viaduct (Welwyn Viaduct) some ten miles to the south, the flat junction just north of Hitchin was a major bottleneck,[7] as northbound trains diverging from the East Coast Main Line towards Letchworth and thence to Cambridge had to cross one northbound (fast) line and two southbound (fast and slow) lines to access the Cambridge Line. Proposals as part of the original electrification work envisaged a new underpass here and land was set aside for its construction. However, budgetary constraints forced this part of the programme to be abandoned. The land stood empty for many years, but has since been used to provide new housing.

A new plan[8] and subsequent application for an order[9] to build a flyover was approved, and construction was completed in June 2013. The scheme has created a new single-track line that diverges from the northbound slow line at a new junction just beyond Hitchin station, using a short embankment section of the former Bedford to Hitchin Line, a section of which was cleared of vegetation and made progressively higher, to form a short ramp. The track is carried over the East Coast Main Line on a newly constructed viaduct and onto a new embankment to join the present Cambridge Line at the newly created Hitchin East Junction, closer to Letchworth. Although this takes trains over a longer distance, it removes the need for them to dwell at Hitchin – sometimes for several minutes – awaiting a safe path across the tracks of the main London-Peterborough route, thus decreasing the overall journey time to Cambridge in many instances. The scheme improves the punctuality and reliability of both the London-Cambridge and London-Peterborough routes, because Peterborough-bound stopping trains are no longer delayed if running closely behind a Cambridge service being held at Hitchin waiting to cross the flat junction.

Govia Thameslink Railway

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

In September 2014, services run by First Capital Connect were taken over by a new company called Govia Thameslink Railway. The Great Northern services have their own sub-brand.[10]

Future developments

Thameslink programme

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

As part of the Thameslink Programme,[11] the Great Northern Route will be connected to the existing Thameslink route via a new junction at Belle Isle[12] (south of the High Speed 1 flyover, just north of London King's Cross). Two single-bore tunnels (known as the Canal Tunnels) have already been driven from here to the low-level platforms at St Pancras during the 'St Pancras Box' phase of the redevelopment works that created St Pancras International station. Trains diverging from the Great Northern Route at Belle Isle will join the 'core' St Pancras - Farringdon - City Thameslink - Blackfriars section of the existing Thameslink route and then serve stations across Surrey, East Sussex, Kent, and West Sussex.

East-West (Varsity) line

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

The Varsity Line connected Cambridge with Oxford via Sandy and Bedford ("Varsity" being slang for "University", those termini being major university towns). It was closed in 1967 but there are now proposals[13] to restore this route, but via the Cambridge Line and the East Coast Main Line, diverting westwards at Stevenage.

Rolling stock

While the Great Northern has a distinct set of Rolling Stock, it is detailed together with the Thameslink Rolling Stock here.

Trivia

The Queen and Prince Philip are reported to occasionally travel by scheduled train to reach their country residence at Sandringham, near King's Lynn.[14]
