The Gainsborough Line is the current marketing name of the Sudbury Branch Line, a branch line off the Great Eastern Main Line in the east of England, that links Marks Tey in Essex with Sudbury in Suffolk. It is 11 miles 71 chains (19.1 km) in length and single-track throughout.
Prior to the Beeching cuts initiated in the 1960s, the line, then known as the Stour Valley Railway, continued beyond Sudbury to Shelford in Cambridgeshire. Today the line is part of the Network Rail Strategic Route 7, SRS 07.10, and is classified as a rural line. It is operated by Abellio Greater Anglia.
In 2005 the line received around £3 million of investment, which saw around 5 miles (8 km) of old jointed track replaced with new continuous welded rail. Further investment was made in 2006 to replace around 6 miles (10 km) of track, leaving just the Chappel viaduct and Lamarsh to Sudbury sections in need of modernisation. This work was completed in 2007.
The current name of the line commemorates the painter Thomas Gainsborough, who was born in Sudbury; the previous name was the Lovejoy Line, after the television series Lovejoy, which was filmed in the Sudbury area.
All passenger services on the line are currently operated by Abellio Greater Anglia, which runs an hourly service seven days a week, with frequency increasing slightly during peak hours. One train each day is extended to or from Colchester.
The line is single track throughout, has a loading gauge of W6, and a maximum speed of 50 mph. Unlike other branches in the area, such as the Braintree Branch Line and Mayflower Line to Harwich Town, the Gainsborough Line is not electrified and so trains are formed of Class 153 and Class 156 diesel units.
Accidents and incidents
- On 12 July 1887 one person was killed at Bures when part of a runaway train collided with a crossing gate.
- On 27 January 2006 at least four passengers were slightly injured when a Class 156 train ran into the buffer stop at Sudbury. The 6:05 pm service from Marks Tey was travelling at a speed at the time of the collision of approximately six miles per hour. An investigation determined that the driver failed to apply the brakes in a "timely and appropriate manner".
- On 17 August 2010 the Little Cornard derailment occurred when the 5:31 pm service from Sudbury collided with a lorry that had entered a level crossing without permission. The train driver and four passengers were seriously injured in the accident.
