Template:First Capital Connect services The Great Northern route,[1][2] formerly known as Great Northern Electrics,[3] is a suburban rail route in London and the East of England. The route consists of services on the southern end of the East Coast Main Line, which is the main railway link between the cities of London and Edinburgh,[4] as well as its associated branches, including the Cambridge line, Fen line, Hertford loop line, and Northern City Line.
The route is currently operated by Great Northern, which is one brand under the umbrella of Govia Thameslink Railway.[5] Services originating at London King's Cross operate to Peterborough, Letchworth, Cambridge, Ely, and Kings Lynn, whereas services originating at Moorgate operate to Welwyn, Hertford North, Gordon Hill, and Stevenage.[6]
The route forms a major commuter route into London from Hertfordshire, Cambridgeshire, and eastern Bedfordshire: ridership has grown rapidly over recent years.
Route
The Great Northern route is formed of the Northern City Line, Hertford loop line, the southern section of the East Coast Main Line between London Kings Cross and Peterborough, the Cambridge line, and the Fen line.[7] Since Greater Anglia withdrew its services to King's Lynn in May 2023,[8] Govia Thameslink Railway has been the sole operator of the entire route except between London Kings Cross and Peterborough, and between Cambridge and Ely. The route serves 57 stations.[9]
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. In September 2014, the Department for Transport transferred the new Thameslink, Southern and Great Northern franchise to Govia Thameslink Railway.[10]
History
Script error: No such module "labelled list hatnote". The term Great Northern is related to the Great Northern Railway, the original builders of the line.
The July 1922 Bradshaw's Railway Guide stated a typical rail service on the Cambridge Line as follows:[11]
- Template:Rws to Template:Rws - Six stopping and two (three on Saturday) semi-fast services from Monday to Saturday, one northbound and two southbound stopping services on Sunday. The fastest service took about 1 hour 30 minutes.
- London King's Cross to Template:Rws - Two (three on Wednesday) additional services from Monday to Saturday, one additional service on Sunday.
- London King's Cross to Template:Rws - Seven additional services from Monday to Saturday.
- London King's Cross to Template:Rws - Three additional services from Monday to Saturday. The last service on Wednesday ran past midnight into Thursday morning.
Since the 1960s, Great Northern has been used to describe the suburban part of the East Coast Main Line, south of Template:Rws and south of Template:Rws. The Great Northern Railway had proposed electrification of part of the line in 1903, but it was not until 1971 that a scheme to electrify the line from Template:Rws and Template:Rws was authorised.[12]
The Inner Suburban Lines to Template:Rws and Template:Rws were electrified in 1976 with Template:Brc EMUs. In 1978 the electrification was complete to Royston with Template:Brc EMUs providing the service. The route was then promoted as the Great Northern Electrics.[12] The route between Hertford and Langley Junction, south of Template:Rws, was also electrified but not regularly used by electric trains until 1979, when one Moorgate - Hertford service per hour was extended to Template:Rws; prior to this DMUs provided an infrequent service over this route, running between Hertford and Template:Rws / 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 Template:Rws in 1986.
With the further electrification of the East Coast Main Line between 1986 and 1988, electric services could be extended to Peterborough and the outer suburban service was changed from Template:Brc to Template:Brc, some of which were cascaded from the newly created Thameslink route, with the remainder newly built.
In 1984[13] it was decided to electrify the line between Royston and Shepreth Branch Junction, a junction on the West Anglia Main Line north of Template:Rws, allowing the reinstatement of through services to Template:Rws from London King's Cross via the East Coast Main Line, which was faster than the conventional route from Template:Rws 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 the maximum line speed was raised to 90 mph.
Rapid growth on the route, especially on the Cambridge Line resulted in consultation on a new service pattern,[14] 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
Script error: No such module "Labelled list hatnote".
Together with the two-track Digswell Viaduct (Welwyn Viaduct) some ten miles to the south, the flat junction just north of Template:Rws was a major bottleneck,[15] 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[16] and subsequent application for an order[17] 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 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.
Thameslink programme
Script error: No such module "Labelled list hatnote". As part of the Thameslink Programme,[18] the Great Northern Route has been connected to the existing Thameslink route via a new junction at Belle Isle[19] (south of the High Speed 1 flyover, just north of London King's Cross). Two single-bore tunnels (known as the Canal Tunnels) were driven from here to the low-level platforms at Template:Rws 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 join the 'core' St Pancras - Template:Rws - Template:Rws - Template:Rws section of the existing Thameslink route and then serve stations across Surrey, East Sussex, Kent, and West Sussex.
On 6 November 2017 the first Thameslink Programme units entered service on the Great Northern route.[20] 700128 worked the 0656 Peterborough – London King's Cross and 1812 return, while 700125 worked the 0733 Peterborough – London King's Cross and 1742 return.[20]
Services
Off-peak
The Great Northern MondayTemplate:NdashFriday off-peak service pattern, as of May 2025, with frequencies in trains per hour (tph), consists of the following:[21][22]
Peak hours
During peak hours, all services from London King's Cross to Letchworth Garden City (see table above) are extended to/from Cambridge, resulting in a 2tph 'stopping service' between London King's Cross and Cambridge.[23] During peak hours, Great Northern runs 5 'limited stop' services in each direction between Template:Rws and London King's Cross, with calls at Huntingdon, St Neots, Biggleswade and Stevenage only.[23] In addition, during peak hours, Great Northern runs 3 'limited stop' services in each direction between Letchworth Garden City and London King's Cross, with calls at Hitchin, Knebworth and Welwyn North only.[23]
Rolling stock
Govia Thameslink Railway
The majority of Great Northern services are operated with Template:Brc Electrostar units.[24] On 12 March 2024 it was announced that Great Northern would lease 30 Class 379 units from Porterbrook.[25] These were introduced for their services to Letchworth in February 2025,[26] which replaced Class 387 units in order to allow them to be transferred to Southern.[24]

Future developments
Cambridge South railway station
A station to the south of Cambridge was first proposed in 2017,[34] and although its application to New Stations Fund 2 that year was unsuccessful,[35] the November 2017 budget allocated it £5 million in funding.[36] The station, called Cambridge South, is situated between Foxton and Cambridge on the Cambridge line, and will serve the Cambridge Biomedical Campus and the wider Trumpington area.[37] The station is set to open in early 2026, which is a delay from the originally proposed date of late 2025.[38] The station will be managed and served by Greater Anglia and East West Rail,[39][40] with no further confirmation as to whether Great Northern, Thameslink, or CrossCountry will also serve the station.[39]
East West Rail
The route of East West Rail, the new railway linking the cities of Oxford and Cambridge, will intersect with the East Coast Main Line at Tempsford in Bedfordshire, where a new station will be built to serve both routes. This has led to worry from local residents, particularly due to a report by East West Rail that the population of the village could grow from 600 to 44,000.[41] As a result of extra funding in the 2024 budget, East West Rail will deliver the station five years earlier than planned, allowing passengers on the East Coast Main Line to access the station before it opens as part of the East West Rail route.[42]
Both Cambridge South and Cambridge stations on the Cambridge line will also be served by East West Rail, the Template:Rws–Cambridge section of which is in detailed planning as of 2025.Template:Sfnp The current plan for the route will include a grade-separated junction with the line at Hauxton, between Foxton and Cambridge. This will include improvements to Hauxton level crossing.Template:Sfnp East West Rail confirmed in their 2021 consultation that the Cambridge line will remain double-tracked between this junction and Shepreth Junction, where the line will be quadrupled to run alongside the West Anglia Main Line as far as Cambridge.[40]
