UK rail operator Network Rail has begun a £21m track replacement project on the Boston-Skegness rail line using fully recycled materials.

The project involves renewing the three decades-old 32 miles of track with 100% recycled rail, sleepers and ballast.

The ongoing Phase I of the project, to replace the first 12 miles of track, is expected to finish in early November.

The project’s second phase, to replace the remaining 20 miles, is expected to finish by March 2010.

The project will provide a smoother train ride due to shift from jointed track to continuously welded rail as well as provide access for different types of trains, increase trains speeds and make the railways greener.
