NWRL sustainability principles

Leadership: coordinated and transparent implementation and decision making, engaging with stakeholders and suppliers, encouraging innovation and demonstrating sustainability leadership.

Environmental Responsibility: enhance the natural environment and reduce the project ecological footprint.

Climate: mitigate impacts on, and adapt to future changes in, climate.

Customer: provide accessible, safe, pleasurable, and convenient access and transport service for all customers.

Place: Create desirable places, promote livability, cultural heritage,optimise community and economic benefit.

For the NWRL, sustainability means building a rail system for current and future generations, that optimises environmental and sustainability outcomes, transit service

quality and cost effectiveness.

Station precinct & corridor design principles

1. Customer Needs:

• Access routes accessible to all – ‘door to door’

• High quality public realm with a mix of complementary uses

• Pedestrians privileged & precincts safer by design

2. Connected Transport:

• Stations connected into existing and planned transport networks

• Comfortable environment with weather protection for interchange

• Legible connectivity between modes at interchanges

• Pleasant walking and cycling routes.

26

Station precinct & corridor design principles

3. Attractive Places:

• Reinforce the natural and built fabric

• Provide a sense of place and focus for the community

• Locate station entries prominently

• Respond to heritage and cultural values

4. Informed by Natural Systems:

• Respond to topography, landform, natural patterns and systems

• Maximise views, access and connectivity along & across the corridor

• Restore and enhance ecological integrity

• Robust and low-maintenance landscape systems.

27

Station precinct & corridor design principles

5. Catalyst for Change:

• Enable a robust street pattern and public spaces as the backbone for future development

• Encourage sustainable travel behaviour

• Facilitate Transit Oriented Dev (TOD) and revitalisation of precincts around stations

• Ensure land uses around stations can change over time.

Rail Systems – emerging design (1 of 3)Reviewing the design for a range of train plans from 4 trains per hour up to a maximum of 16 trains per hour;Direct connection into the Epping Chatswood Rail Line.

High Voltage Bulk Supply is required (132kV) from the local supply authorities;Traction 1500VDc – this is to be modelled to ensure new line is integrated in the Rail.

Station and Tunnel control systems, CCTV, Radio, IT, SCADA, Fibre optic trunking;Telephone system;WiFi system Hot Spots;Passenger Information systems;Ticketing System.

3 minute headway;European Train Control System Level 1 (this is currently being

developed and installed in the Railcorp network).

Rail Systems ‐ emerging design (2 of 3)Overhead wire configurations;11kV network to supply the stations;Low Voltage network;Lighting.

Fixed track in the tunnel like ECRL;Floating Slab Track will be installed where required for noise mitigation;Ballasted track on the open areas;Crossovers to support OperationsTrack speeds of 100km/h in tunnel and 130km/h above ground;Max 3% grade

Ventilation System;Hydraulics system;Fire detection systems;Vertical transportation (lifts escalators);Temperature control

Initially for 16 x 8 car sets;Future-proofed for expanded operation if required

Engineering ChallengesDesigning public infrastructure and rail alignment that is best for customer i.e. shallow stations, straight alignment, flat, safe.Design Assurance and operator concept approval. Process evolving as the industry comes to terms with the Rail safety Act2008

Specialist resources in the industry are in short supply (i.e. Signalling / Electrical)Infrastructure design to achieve the aspirational customer comfort levels. Design for alternate project delivery options and phasing.TBM bored tunnel vs roadheader, insitu vs precast tunnel lining, drained vs undrained structures, single vs tri-bore and whole of life assessments.

Industry Consultation / Market Sounding

Objectives• engage with relevant industry sectors on the NWRL delivery strategy

• secure the best international expertise and advice

• achieve value for money by ensuring that the NWRL Project–be procured from a competitive market place–be delivered cost effectively, within the timeframe required–be consistent with capital, operating and maintenance budgets

• meet relevant operating, safety, community and environmental standards and parameters.
