CONTRACTS

HASWELL IS helping ease rail disruption for train users in Kent with the start of what it claims is the longest tunnel relining project of recent times.

Haswell has been commissioned through Parsons Brinckerhoff by Network Rail to assist in provision of construction management services on the 19th century double-track tunnels linking Strood and Higham in north Kent. where chalk has been falling from unlined sections.

The project spans 3.5km and has led to the tunnel closure for 12 months, suspending train services between the two stations.

Steel support arches and concrete lining will be used to reinforce the unlined sections and provide refuges and shaft stabilisation. Further work includes installation of a drainage system to protect the line from rising water levels from the Thames and Medway Rivers, a complete renewal of the tracks, temporary signalling, telecommunications and renewal of 33kV HV cable.
