As part of the biggest upgrade to Sydney’s busiest railway station in decades, Directhitt Trenchless were contracted to supply and install 4 DN 630 HDPE conduits to provide 33KV power to the new Metro station. The boreholes connected the 27m deep Metro station box Level B2 to an existing Ghost Tunnel, which was built last century as part of the Eastern Suburbs Railway line for Bondi and the Illawarra but never completed. Platforms 26 and 27 have sat unused since, but they will now house 17 new communications and power rooms to support the new Sydney Metro at Central Station.
