Sydney Metro

Alastair Taylor's picture

All figures in headline and broken down sections from the main website - just putting it all in one page if anyone wants to reference it in future. As many might have realised, I'm a stickler for technical detail.

Headline stats/figures

- $8.3 total budget
- 23 km of newly built track, conversion of the 13km Epping-Chatswood underground link built last decade.
- Automated/driver-less trains to run from Chatswood out to Rouse Hill (directly West of Hornsby and South East of Windsor/Richmond) on 4 minute frequencies in peak.
- Station platforms will be 168m in length (effectively the same length as the exiting network in Sydney, compared to a standard station in Melbourne 145-150m) - which will support 8 car trains at full capacity, services will start with 6 car services.
- Trains are single deck and will always be single deck.

All the planning documents for the project are located here:


PPP with three primary contracts that have been now all tendered out by NSW Gov.

Contract 1

Includes the tunnelling, civil works at 5 stations on the underground section and excavation and civil works for service facilities at Cheltenham and Epping - JV website:
- Contract value: $1.15billion.
- Contract value per kilometre: $76.6 million per k/m.

Twin tunnels mostly being built with 4 TBMs, tunnel tracker:
Tunnel measurements:
- total length 15 km
- internal diameter of a single tunnel: 6m
- average depth 29 metres, greatest depth 58 metres.
- tunnels will have two cross-overs

5 Stations built with differing methods - two open-cut and three underground cut & cover
- Bella Vista (open-cut), located at the end of the tunnels

- Norwest (underground C&C).

- Showground (underground C&C).

- Castle Hill (underground C&C).

- Cherrybrook (open-cut).

Open Cut = station is open-air, but located below ground level.
Underground cut and cover = a "station box" is excavated to create the space for the platforms/station facilities and then covered.

Contract 2

Includes the construction of an elevated section of track, two stations and a cable stayed bridge across Windsor Road, JV website:
Contract value: $340 million
Contract value per kilometre: $85 million per k/m**
*** this is just the total / 4km. There's no explicit information on who's responsible for the grade sections or the Cudgegong Road station - I'd assume it is this contract, if so the $ per k/m would lower as there's approximately another 4km of "unaccounted for" track in the official information on the project's website (total length: 23km, accounted for: 15km tunnels, 4 km of skytrain, unaccounted for: 4km).
If we assume this contract includes the missing 4km then it's cost per km is $42.5 million per k/m for the civil and station works at grade and elevated.

The 'skytrain' is a 4km section of elevated track
- deck width: 11m
- no information on the pier diameter

- Windsor Rd bridge:
-- Cable-stayed bridge on a continuous curve.
-- 270m long.
-- Central span 131m
-- Twin towers with heights of 45m.

Two elevated stations
- Kellyville.

- Rouse Hill.

Contract 3

It's the largest contract and it's a Operations, Trains and Systems (OTS) contract. Contract was awarded to the Northwest Rapid Transit consortium which includes according to a Leighton media release:
Contract value: $3.7 billion

Delivery of the infrastructure and rail systems: John Holland Group, Leighton Contractors, MTR and UGL Rail Services
Financial sponsor and capital arranger: Plenary Group
Operation and maintenance of system post construction completion: MTR Corporation – with John Holland and UGL Rail Services
- the operation part of the contract is for 15 years.

[i]- can't find explicit information on this, but I assume that a large part of the contract value will be dedicated to the cost of operating the services and maintaining the infrastructure for 15 years, thus NSW Gov will be paying instalments over 15 years

The rail vehicles will come from Alstom's Metropolis suite of Urban/Metro products
- Metropolis is just a brand name for all its trains which work best in urban (as opposed to mainline) environments.
- One city that uses Metropolis trains in a metro style system will have different specifications to another city - i.e train width, train height, 3rd rail or overhead power, number of doors per car etc - there's a high degree of localised specification for each system/everyone doesnt use the same specifications.

The communications-based train control will be Alstom's Urbalis 400
- the system that will enable the trains to run driver-less / remotely from a control room.

Contract also includes the construction of the Rapid Transit Rail Facility at the end of the line beyond the Cudgegong Road station as well as an operations centre.

This contract also includes the work required to convert the existing Epping-Chatswood rail line: installing the Urbalis system in the tunnels, adding platform screen doors to existing stations etc.

Development & Planning

Wednesday, December 13, 2017 - 12:00
The swirl of development activity in Footscray has found another gear as new projects are submitted for approval, or are on the verge of beginning construction. Two separate planning applications have been advertised by Maribyrnong City Council; their subsequent addition to the Urban Melbourne Project Database has seen the overall number of apartment developments within Footscray in development swell to 40.

Policy, Culture & Opinion

The marriage of old and new can be a difficult process, particularly when the existing structure has intrinsic heritage value. In previous times Fitzroy's 237 Napier Street served as the home of furniture manufacturer C.F. Rojo and Sons. Taking root during 1887, Christobel Rojo oversaw operations though over time the site would become home to furniture manufacturer Thonet.


Visual Melbourne

The former site of John Batman's home, Batman's Hill is entering the final stages of its redevelopment. Collins Square's final tower has begun its skyward ascent, as has Lendlease's Melbourne Quarter Commercial and Residential precinct already. Melbourne Quarter's first stage is at construction and involves a new 12-storey home for consultancy firm Arup along with a skypark.

Transport & Design

Infrastructure Victoria unveiled a new round of research into its larger programme of work dealing with managing transport demand. The authority contracted Arup and KPMG to produce the Melbourne Activity Based Model (MABM) and while it is new, it is considered fit for purpose in the strategic context.

Sustainability & Environment

Cbus Property's office development for Medibank at 720 Bourke Street in Docklands recently became the first Australian existing property to receive a WELL Certification, Gold Shell and Core rating. The WELL rating goes beyond sustainable building features with a greater focus on the health and well-being of a building's occupants.
