Dismantling and installation of the support structures, catenary, plus DSS in the tunnels
Route length
14 km
Short description
A total of ten tunnels and eight bridges were fully refurbished in the cluster project. The support structures and catenaries had to be dismantled first, and then rebuilt in the final stage. The poles on the 14 km section were flown in and placed by helicopter. The challenge was to keep to the tight construction schedule while coordinating operations with the work of other contractors.
