The High Marnham Test Track is a linear railway test track created in 2009 and centred on Lodge Lane,
Tuxford, in Nottinghamshire in the United Kingdom.
It houses
Network Rail's Rail Innovation & Development Centre (RIDC),
originally known as the Rail Vehicle Development Centre (RVDC).
The main route is approximately long
and rated for speeds up to .
It is primarily formed of a former section of the
Lancashire, Derbyshire and East Coast Railway running between Thoresby Colliery Junction at the western end, and
High Marnham Power Station at the eastern end.
Additionally a branchline diverges northwards over the
Bevercotes Colliery Branch via Boughton Brake Tunnel to
Bevercotes.
The main test track passes on a bridge directly over the
East Coast Main Line

, at the location of the former
Dukeries Junction interchange station, but without a rail connection being provided.
Instead the test track is accessed from the
national British railway network via Shirebrook Junction on the
Robin Hood Line and the existing line from there to Thoresby Colliery Junction.
Access for trains is protected by an

In British, Australian, French, and Swiss railway signalling, an Annett's key is a form of trapped-key interlocking that locks levers or other items of signalling apparatus, thereby serving as a portable form of interlocking. The purpose is to ...
under the supervision of an Engineering Technical Officer.
There is no signalling on the line owing to theft and vandalism, including the previous destruction of the Ollerton Colliery signal box.
Re-opening
On 10 February 2009
975025 ''Caroline'' visited the line on inspection duties prior to re-opening.
Network Rail announced their intention for the reopening between Thoresby Colliery Junction and High Marnham on 10 July 2009. In August 2009 Network Rail stated that because the route of the line would now be maintained, it might increase the likelihood of being able to restore a passenger service in connection with Robin Hood Line services at a later date.
In November 2011 local people were reminded about the operational nature of the test track following acts of trespass.
During 2012 the Branch Line Society announced their intention to run a
railtour covering the main test track and special steep gradients; plus the Bevercotes Branch to a distance of . Such a tour ran on 5 January 2013 and was widely reported in the railway enthusiast press.
This line has been identified by Campaign for a Better Transport as a priority 1 candidate for reopening.

25 kV AC railway electrification
Railway electrification systems using alternating current (AC) at are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60Hz), which simplifies traction substations. The dev ...

and facilities for
ERA Technical Specifications for Interoperability (TSI) noise testing.
An area of special track exists for RIS-1530-PLT testing of on-track plant, including lengths of track for brake testing at up to 1:25 and sharp
reverse curves.
The Lodge Lane area also contains
portacabins for visiting staff, and a inspection shed for railway vehicles.
Projects
In March 2012 braking tests were undertaken for fitments of improved
hydraulic brake
A hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism.

These excavators were all falling under classification "type 9b" where the rubber wheel touch small flanged steel wheels, which in-turn touch the rails and were found to have significantly reduced braking performance in adverse conditions.
In August 2012 the line was used for the testing of
