The work involves replacing ballast and track, as well as the overhead catenary and upgrading the power supply system. Drainage will also be improved, noise barriers erected, and improvements will be made to reduce the impact on operations from farm animals crossing the track.

Several stations on the line will be reconstructed to improve accessibility for disabled passengers.

The work will begin this year and when it is completed at the end of 2016 passenger trains will be able to operate at 160km/h while the maximum speed for freight trains will be increased to 120km/h.
