The Midland Main Line between London St Pancras and Sheffield is one of the busiest stretches of line in the UK. Network Rail wanted to improve the line to allow the introduction of an increased line speed to 125mph.
The programme of work included a total of 159 miles, which needed upgrading, replacement of a number of level crossings with bridges, re-signalling and re-alignment of parts of the track along with the creation of a safer environment for future maintenance work. All of the work needed to be carried out within the prescribed Network Rail timetable and with the safety of maintenance personnel the priority at all times.
The scale of the improvement project can be gauged by the fact that over 50km of new signalling cabling was installed and over 30 signalling commissioning's were carried out on the project. In addition, over 400 positions of safety were installed with over 100 new speed signs were installed.
What's more, the project was delivered whilst maintaining the highest standards of health and safety:
