Eurostar Trains Commence Services


Costain is delighted to have played a major role as part of the CORBER joint
venture in the refurbishment of St Pancras station, part of the £5.8 billion
Channel Tunnel Rail Link and St Pancras refurbishment project.


The first scheduled train services commence operation into and from St Pancras
today.


At the official opening of the new St Pancras Station and Eurostar Terminus last
week, specific mention was made of the highly technical and intricate nature of
the work undertaken.  In particular, it was noted that the project, which took
10 years to complete, was delivered ahead of schedule and on budget.


Andrew Wyllie, Chief Executive of Costain, said:


'This was a flagship project not just for Costain but for the country as a
whole, probably the largest and most complex civil engineering project
undertaken since the Thames Barrier which Costain also played a key part in.


'We are proud to have been a part of this major achievement.  It is a great
testimony to the skills and capability of Costain and our joint venture
partners, and we look forward to securing further such prestigious projects in
the future.'
