Rail contractor QTS saw pre-tax profits rise by 43 per cent last year.
Following the announcement of its record-breaking results, the firm announced that it will be “actively” seeking to take on projects in the Far East and Australia.
The company, which is based in Drumclog in Lanarkshire, said turnover soared 75 per cent to £24.1 million for the year to March 31, with pre-tax profits increasing by 43 per cent to just over £2 million.
Last year, QTS was involved in a number of significant rail projects, including the refurbishment of Dove Holes tunnel in Derbyshire.
QTS was also awarded the Network Rail BCDP (Building and Civil Delivery Partnership) for the Northern region in 2011.
Director and founder Alan McLeish said: “This growth has been fuelled by winning more framework contracts and alliances within the UK rail sector, improved supplier relationships and our increased capability to deliver more works.
“These results allow us to really build for the future, whether that is with overseas work, developing our workforce or investing in green energy at our HQ.
“Crucially these results allow us to reinvest profit in our road-rail vehicle research, development and production at Rench Farm which will help keep us ahead of our competition in railway operations.”
