NORTH WEST RAIL LINK| UPDATE| ELIZABETH| TUNNELLING HAS STARTED| NORWEST STATION EXCAVATION ABOUT 75% COMPLETE

 Update regarding developments on the North West Rail Link (NWRL) and the Norwest Station site.

Exciting news as the first tunnel boring machine ‘Elizabeth’ has officially started the tunnelling within the NWRL. The TBM will tunnel 24 hours a day in line with the Environment Protection Authority licence conditions for the project.

Since launching on 8 September, Elizabeth has tunnelled more than 90m towards the Norwest Station site, which is allowing the team to assess the TBM’s operations and the geotechnical conditions. Elizabeth is expected to progress at about 120 m a week on average.

Excavation of the Norwest Station area continues 24/7. Excavation is about 75% complete, with around 50,000 tonnes of crushed rock (spoil) still be removed.

The team has also started excavating two arched cavities, known as nozzles, at both ends of the station area. This is where the tunnel boring machines will enter from the Bella Vista end and leave as they make their way on to the Showground Station site.

Out-of-hours deliveries and removal of oversized equipment will continue to occur between 12 am and 6 am on Mondays, Wednesdays and Thursdays. These hours are necessary due to Roads and Maritime Services restrictions on oversized vehicles to minimise the impact on local roads. The oversized equipment such as excavators and dump trucks are interchanged between construction sites to meet maintenance or work requirements.
