| 摘要： | A 11,000-tonne concrete tunnel will be installed over nine days to a section of the East Coast Main Line (ECML) as part of £1.2bn upgrade works. The structure has been built at the side of the track for the last nine months and is now ready to be pushed into place along pre-installed guided supports. Installing the tunnel will cause a reduced service on the line but will avoid the usual closure of the track. |
