Maintenance and rehabilitation of sea walls and revetments between the Glencairn and Simonstown stations

摘要

The railway line between the Simonstown and Fish Hoek train stations is protected by sea walls which were constructed almost a century ago. In order to protect the railway line, concrete sleepers were placed in front of these walls during the 1970s. Over the last five years this intervention has been shown to be inadequate and an engineered solution was required over limited critical sections of the line. The November 2009 storms resulted in sections of the sea wall failing after being severely undermined. Passenger train operations were halted on the line in December 2009 due to public safety being compromised. After a design, procurement and stakeholder engagement process the necessary rehabilitation work was undertaken and completed in February 2011. Normal train operations were restored on 21 February 2011, the construction works having been completed within budget and within an acceptable time-frame
