Work includes a new station in Edinburgh, bridgework and electrification of lines

Morgan Sindall, Bam Nuttall and Carillion have won 拢55m of work from Network Rail for improvements in the Edinburgh to Glasgow corridor.

Bam Nuttall is the biggest winner and will build 18 structures, mostly bridges, along the lines at a cost of 拢27m.

Morgan Sindall will build a new 拢25m station at Haymarket in Edinburgh, which will be fully integrated with the city鈥檚 tram and bus networks.
