Network Rail will be completing new signalling on the Robin Hood Line north of Nottingham this weekend.
The equipment, which has been installed over several months, will allow the railway between Radford Junction (north of Nottingham) and Shirebrook to be controlled from a single desk in the East Midlands Control Centre at Derby.
The £6M project will allow Network Rail to close Kirby Summit signal box.
Line upgrade is part of a programme of resignalling in the East Midlands. The series of 13 individual projects began in October 2005 and is progressively renewing the signalling on the Midland Mainline from London St Pancras International to Sheffield with modern equipment.
Other works carried out at the same time include upgrading the fixed telecoms network, freight sections of track, remodelling junctions and changes to level crossing operations that will lead to improved train punctuality. All of the renewed signalling will be controlled from the purpose built East Midlands Control Centre in Derby.
