A) SOUTHERN SECTION
1. Underground section
All tunnel excavation – a total length of approximately 15.5 kilometers from Park Station to Marlboro Portal – was completed in September 2009. Civil works, tracklaying and associated electrical & mechanical railway infrastructure works within the tunnels between Marlboro Portal and Sandton Station are complete.
Whilst diesel-powered construction trains have been operating within this section of tunnel for some time, a noteworthy milestone achieved during the month was the energization of the lines to Sandton on 26 February 2010. Since then, the Gautrain Electrostar trains have been test running between ORTIA and Sandton on a regular basis.
Within the remaining tunnel section to Park Station, civil works, including final lining, invert slabs, cable duct installation and walkways, together with the installation of mechanical and electrical equipment, are ongoing. Tracklaying from Sandton Station towards the south will commence shortly.
The underground works also include the construction of seven emergency access shafts located at intervals along the single-track rail tunnel between Park Station and Sandton Station. These shafts will provide emergency services personnel access to the tunnels below. At the bottom of certain of these shafts there will be safe havens where passengers can gather in case of an emergency. Construction works are ongoing at each of these emergency access shafts.
Construction of the adjacent multi-level parkade at Johannesburg Park Station
Within the underground station, internal brickwork and plastering are well advanced and wall and floor tiling at concourse level are in progress. Mechanical and electrical (M&E) installations are ongoing and escalator installation has started. At the parkade structure being constructed above the station, four of the six levels of parking deck slabs have been cast.
