In March 2012 the Welsh Assembly announced that sections of the line would be part of a £46-million improvement scheme. This included redoubling the track between Wrexham and Chester (Rossett Junction and Saltney Junction) and upgrading certain sections of line to allow trains to run at 90 mph. Work started on this project in June 2014 and was scheduled for completion in Spring 2015, but it was delayed until April 2017 by Network Rail due to the need for signalling cables to be replaced in addition to the track, signal and level crossing upgrades already installed.
