Silverlink [1] was a train operating company in the United Kingdom owned by National Express that operated the North London Railways franchise from March 1997 until November 2007. At the end of 2007 Silverlink Metro services were taken over by London Overground and Silverlink County services were taken over by London Midland.
The North London Railways franchise was awarded to National Express on 7 February 1997. [2] National Express commenced operating the franchise on 3 March 1997.
After initially trading as North London Railways, in September 1997 the franchise was rebranded as Silverlink. [3]
The franchise was due to finish on 15 October 2006, but on 11 August 2006 the Department for Transport granted an extension until 10 November 2007. [4] Upon its closure, its London metro services were taken over by London Overground and the remainder were merged with Central Trains' western services to form London Midland.
Silverlink had two sub-brands:
Silverlink Metro was used for services primarily within Greater London:
Silverlink County was used for services beyond Greater London:
Silverlink Metro operated these services.
Note: Changes during the franchise period are noted but changes to the lines before and after the franchise are not.

Silverlink was categorised as a London and South East operator by the Office for Rail Regulation (ORR) and was one of the best performing TOCs in this sector with a PPM (Public Performance Measure) of 90.8% for the last quarter of the financial year 2006/7. [7] Despite these figures, [8] the Silverlink Metro franchise on the North London Line was regarded by frequent travellers as offering a poor service, [9] with extremely congested trains and an unreliable service [10] with some trains cancelled shortly before they were due to arrive. A London Assembly report said passengers found the service "shabby, unreliable, unsafe and overcrowded". [11]
Silverlink inherited a fleet of Class 117 and Class 121 diesel multiple units, and Class 313 and Class 321 electric multiple units, from British Rail.
To replace the elderly Class 117s and 121s, which operated the Gospel Oak - Barking and Bletchley - Bedford services, seven Class 150 Sprinters were transferred from Central Trains in summer 1999; an eighth followed in 2006. [12] [ full citation needed ] Pending the Sprinters' arrival, Silverlink hired Class 31 locomotives from Fragonset to top and tail Mark 2 carriages on Bletchley - Bedford services in 1998/99.
The Class 313s operated Metro services on the electrified routes; they were joined on the Euston - Watford Junction service in 2003 by three Class 508s transferred from Merseyrail. The Class 321s operated County services to Northampton and Birmingham; they were joined in 2005 by new Class 350s. The Watford Junction - St Albans Abbey service was operated for many years by Class 313s, but later was usually operated by Class 321s with Silverlink Metro drivers and Silverlink County guards.
On 16 July 2004, Virgin Trains announced that it was withdrawing most of its stops at Milton Keynes Central, which were used by up to 6,000 passengers a day. Commuters became unhappy at the prospect of switching to older Silverlink trains, and a longer journey. Silverlink countered this with the temporary usage of ex-Virgin stock, still in Virgin colours. [13]
The Strategic Rail Authority decided to divert thirty four-carriage Siemens Desiro trains from an order placed by South West Trains to provide stock with faster acceleration for the West Coast Main Line operators. These trains, the Class 350s, were not allocated to a specific operator, but were instead used jointly by Silverlink and Central Trains, both owned by National Express.
Pending the arrival of these trains, from September 2004 Silverlink introduced two sets of Mark 3 carriages, formerly of Virgin Trains, hauled by Virgin Class 87 and EWS Class 90 electric locomotives on peak-hour Northampton services. [14] [15] Additionally, five Class 321s were hired from One, another National Express-owned operator.

Silverlink's fleet was maintained at Bletchley Depot. Following Virgin Trains ceasing to operate electric locomotives, Silverlink's Metro fleet moved to Willesden Depot.
In 2006 Alstom proposed closing Willesden. The depot's closure would have meant the Class 508s would have had to relocate to another depot, and the Class 313s having to return to Bletchley Depot (which was also due to close). On 12 May 2007, Silverlink took over direct running of the depot and its staff for the final six months of its franchise.
As part of a wider redrawing of the rail franchise map by the Department for Transport, the Silverlink network was to be broken up when it was renewed in November 2007.
The Silverlink Metro services were moved to the control of Transport for London under the banner of the London Overground. On 19 June 2007 Transport for London announced it had awarded the London Overground concession to a Laing Rail/MTR joint venture. [16]
The Silverlink County services were merged with the Central Trains services around Birmingham to create a new West Midlands franchise. On 22 June 2007 the Department for Transport announced it had awarded the West Midlands franchise to Govia. [17]
Silverlink's services transferred to London Overground Rail Operations and London Midland on 11 November 2007.
The West Coast Main Line (WCML) is one of the most important railway corridors in the United Kingdom, connecting the major cities of London and Glasgow with branches to Birmingham, Manchester, Liverpool and Edinburgh. It is one of the busiest mixed-traffic railway routes in Europe, carrying a mixture of intercity rail, regional rail, commuter rail and rail freight traffic. The core route of the WCML runs from London to Glasgow for 400 miles (644 km) and was opened from 1837 to 1881. With additional lines deviating to Northampton, Birmingham, Manchester, Liverpool and Edinburgh, this totals a route mileage of 700 miles (1,127 km). The Glasgow–Edinburgh via Carstairs line connects the WCML to Edinburgh. However, the main London–Edinburgh route is the East Coast Main Line. Several sections of the WCML form part of the suburban railway systems in London, Coventry, Birmingham, Manchester, Liverpool and Glasgow, with many more smaller commuter stations, as well as providing links to more rural towns.
The North London line (NLL) is a railway line which passes through the inner suburbs of London, England between Richmond in the south-west and Stratford in the east, avoiding central London. Its route is a rough semicircle.
Kensal Green is a railway station served by London Underground Bakerloo line and London Overground trains. It is located in College Road, London NW10 close to the junction with Harrow Road.

The British Rail Class 313 was a dual-voltage electric multiple unit (EMU) train built by British Rail Engineering Limited's Holgate Road carriage works between February 1976 and April 1977. They were the first production units that were derived from British Rail's 1971 prototype suburban EMU design which, as the BREL 1972 family, eventually encompassed 755 vehicles over five production classes. They were the first second-generation EMUs to be constructed for British Rail and the first British Rail units with both a pantograph for 25 kV 50 Hz AC overhead lines and contact shoe equipment for 750 V DC third rail supply. They were, additionally, the first units in Britain to employ multi-function automatic Tightlock couplers, which include electrical and pneumatic connections allowing the coupling and uncoupling of units to be performed unassisted by the driver whilst in the cab.
The British Rail Class 321 is a class of electric multiple unit (EMU) passenger train built by British Rail Engineering Limited's York Carriage Works in three batches between 1988 and 1991 for Network SouthEast and Regional Railways. The class uses alternating current (AC) overhead electrification. The design was successful and led to the development of the similar Class 320 and Class 322.
The British Rail Class 350 Desiro is a class of electric multiple unit passenger train built by Siemens Transportation Systems to its Desiro design between 2004 and 2014. All 87 are now operated by West Midlands Trains, having previously been operated by Central Trains, Silverlink, Southern, London Midland, First TransPennine Express and TransPennine Express (FirstGroup).
