Doomed construction firm Carillion was working on the new Thameslink station in Cricklewood, it has been revealed.

Barnet Council confirmed that, though they have no direct contracts with the company, some work on the new Thameslink station was subcontracted by Network Rail to Carillion.

The support services company collapsed on Monday with a reported debt of £1.5billion, and held various contracts with the government and Network Rail.

Their work with regard the new Brent Cross West station was in "early contractor involvement and constructability/logistics advice."

A Network Rail spokesman said: "Carillion’s work for Network Rail continues for the time being as Network Rail works with the official receiver and special manager to ensure the continuity of its project work.

"Passengers can be reassured that their services will be running as normal today as Carillion's work for Network Rail does not involve the day-to-day running of the railway.

"Our aim is to ensure, as far as possible, that this news has as little impact as possible on our projects to grow and expand the railway network."

The spokesman was unable to comment on the specific project in Barnet.

A Barnet Council spokesman said: "The council does not hold any direct contracts with Carillion.We have a design services agreement with Network Rail in relation to the station."

"Some aspects of that design work are subcontracted by Network Rail to Carillion, and we look forward to discussing with Network Rail how this work will be provided going forward."
