Balfour Beatty has been awarded three rail contracts worth £248m ($375m) by the UK's Network Rail.
The first contract is a four-year extension of Balfour’s existing track renewal framework project to 2014, at a cost of £56m ($84.6m).
The contract is expected to be increased to an additional £115m ($174m), following the successful completion of targets in the first year of the contract.
The second contract involves the grinding of plain line rail across the UK, including the operation and maintenance of six of Network Rail’s fleet of rail grinders, at a cost of £50m ($75.6m).
The third contract, a £27m ($40m) Paisley corridor improvement project in Glasgow, includes the construction of a third running line and related overhead electrification additions and modifications, and the remodelling of a number of approach lines.
The Paisley corridor, scheduled to complete in 2012, will run from Gower Street Junction to Arkleston Junction.
