Network Rail has cut the number of suppliers on its framework for track renewals from six to four.
GrantRail Group, a joint venture between steel maker Corus and construction company VolkerWessels, and support services company Carillion Rail will both lose their contracts.
The decision follows a six-month assessment of the company's track renewals, with the proposal to rationalise arrangements originally announced in December 2006.
The four remaining contractors are Amey SECO, Balfour Beatty, First Engineering and Jarvis.
The review examined aspects of the contractors' performance, including corporate behaviour, safety, engineering quality, cost, volume and ability to start and finish work on time.
Peter Henderson, Network Rail's group infrastructure director, said the changes would allow the company to strengthen its relationships with its remaining suppliers, while improving quality, safety and efficiency.
He added: "Longer-term security for the successful contractors coupled with improvements in our ability to define and plan the work, will enable us to create an environment whereby we can all plan work with confidence, promote innovation and invest in equipment and people."
Work transfer between contractors will take place over the next few months.
