Sydney Metro

Earlier proposals

The first proposals for a metro system in Sydney were put forward in 2001, when Co-ordinator-General of Rail Ron Christie released his "Long-term Strategic Plan for Rail" report, outlining long-term goals for the expansion of the rail network. He suggested that a number of "metro" lines—operationally independent from the existing network—should be constructed past 2020 due to capacity constraints. This was later dismissed by the New South Wales Government as only a "shopping list" of potential projects.

The idea for a metro resurfaced in late 2007, when discussions about an underground 'Anzac Line' took place within the NSW Government. The line would have run from West Ryde in Sydney's north-west to Malabar in the south-east, but did not come to fruition. In early 2008, following the shelving of various heavy rail expansion projects from the 2005 Metropolitan Rail Expansion Programme, the Government officially announced the 37 km (23 mi) North West Metro. Expected to cost $12 billion, it would have linked Rouse Hill in Sydney's north-west with the CBD, with construction starting in 2010 and finishing in 2017.

The construction of the North West Metro was however dependent on the privatisation of the electricity network, and after a change of Premier in late 2008 it was cancelled due to budgetary concerns. Its replacement was the 9 km (5.6 mi), $4 billion CBD Metro, a shortened route running from Rozelle in the inner-west and into the CBD through to Central. Construction was scheduled to start in 2010, like its predecessor, but finish earlier in 2015. The CBD Metro was to have formed the "central spine" of a future metro network, with an planned West Metro extension to Westmead and Parramatta to be constructed soon after, subject to Federal funding. Reception to the plans was mixed, with Opposition leader Barry O'Farrell accusing the Premier of "making it up as he goes along" after costings weren't released until after the press conference, and criticism came from the Greens on the grounds that the route seemed designed to pass through marginal electoral seats. The Government's initial submission to Infrastructure Australia for funding was rejected to due "a lack of integrated planning". It was later revealed that the cost had jumped from $4 billion to $5.3 billion in six months, and internal estimates showed that the metro would run at only 15% of its maximum capacity.

The CBD Metro was cancelled in early 2010, after the Premier was deposed a few months before in 2009. The Government had spent almost $410 million on the project. The new Premier Kristina Keneally chose instead to focus on expansion of the existing heavy rail network, including the North West Rail Link and South West Rail Link.

Revival

In mid-2012 the newly elected Coalition government announced Sydney's Rail Future and the NSW Transport Masterplan. Under this proposal, the North West Rail Link would be built as a single-deck, privately operated metro connecting to a future second harbour crossing. These plans received criticism on the basis that they might not have the capacity of existing double-deck trains, and concerns over the inability of trains on the existing network to use the new crossing.

In 2014 the Government announced the second harbour crossing under the name Sydney Rapid Transit, as part of the 'Rebuilding NSW' infrastructure plan funded through the sale of electricity infrastructure. The new railway would cross Sydney Harbour, tunnel beneath the CBD, and join the Bankstown line which would be converted to metro standards.

The system was officially renamed 'Sydney Metro' in June 2015 following the passage of power privatisation bills. Opposing parties warned the government that the sale of the power infrastructure may not provide the capital needed.

Sydney Metro Northwest

The first stage will connect Sydney's north-western suburbs to Chatswood. 23 km (14 mi) of new track is planned between Rouse Hill and Epping, including eight new stations. The 13 km (8.1 mi) Epping to Chatswood rail link will then be converted to rapid transit standards and segregated from the existing Sydney Trains network. Construction on Sydney Metro Northwest began in late 2013 and the first services are scheduled to start in 2019.

In November 2016, Sydney Metro, in particular the John Holland Group, Dragados and Transport for NSW, were awarded the 2016 NSW Premier's Award for Building Infrastructure for the 15 km twin-tunnels in Bella Vista and Epping, which are currently the longest tunnels constructed in Australia. The completion of these tunnels in early 2016 marked the completion of the first stage of Sydney Metro Northwest. The NSW Premier's award recognises "infrastructure projects in the state that make a difference to the local community".

Sydney Metro City & Southwest

Sydney Metro City & Southwest is a proposed 30-kilometre (19 mi) rapid transit railway line servicing Sydney's CBD and southwest. The project would extend Sydney Metro Northwest, currently under construction, from Chatswood on the North Shore, to Bankstown in the city's south-west via the Sydney central business district. The centrepiece of the project would be a new twin-tunnel rail crossing under Sydney Harbour. Together with planned improvements to the Main Western line, the project is expected to increase capacity on the Sydney rail network by up to 60%. The line would allow for the movement of over 100,000 extra commuters across the network every hour. The City & Southwest extension represents the first phase of the "southern sector conversion" envisaged in Sydney's Rail Future.

Sydney Metro West

Sydney Metro West is a separate line between the Sydney CBD and Parramatta. The project was mentioned in a discussion paper released in September 2016 that investigated new rail projects to service Western Sydney and the proposed Western Sydney Airport. Media reports indicated the project had found favour with Transport for NSW and the New South Wales Government. It was announced as an official project on 14 November 2016.

Stations are expected to be located in Parramatta, Sydney Olympic Park, The Bays Precinct (located at either Pyrmont or White Bay) and the Sydney CBD. The line is expected to open in the second half of the 2020s. Extra stations are yet to be confirmed.

The metro project serves a similar area to the previously announced Parramatta Light Rail. On 17 February 2017 it was announced that "stage 1" of the light rail project would run between Westmead and Carlingford, and that a branch to Sydney Olympic Park had been deferred.

Rolling stock

Twenty-two 6-car Alstom Metropolis electric multiple units have been ordered for the network. Each single deck train will feature two dedicated areas for prams, luggage and bicycles. There will be three doors per side per carriage and no internal doors between the carriages. In a 6-car configuration the trains will sit 378 people, with a total capacity of 1,100.

Capacity

Stage 1 is due to operate with 6-car trains running on 4 minute headways using 6-car trains. After the addition of the Stage 2 extension to Bankstown the system will require at least 59 six-car trains to run every four minutes during peak periods. However the stations platforms will be configured to allow for future use of 8-car trains and the signalling system designed to allow for 2 minute headways, both of which are planned to be introduced once sufficient patronage demands it. Eight-car trains have a design capacity of 1,539 customers, and increasing the running frequency to ultimately 30 trains per hour (2 minute headway) would provide a maximum capacity of 46,170 passengers per hour per direction.

To Hurstville

The second phase of the southern sector conversion would see two of the four tracks between Sydenham and Hurstville, part of the Sydney Trains Illawarra line, converted to rapid transit and added to the Sydney Metro network. This would increase rail capacity between Hurstville and the city by 10 trains per hour. Though a precise construction timeframe was not provided, the plan envisages all work being completed by 2031. The Hurstville conversion would add eight stations and 9 km (5.6 mi) to the metro network. Developing plans for this extension has proven difficult and the Sydney Morning Herald reported in February 2016 that the project may have been dropped.

Western Sydney routes

A scoping study into rail investment to service Western Sydney and the proposed Western Sydney Airport was announced by the New South Wales and Australian governments in November 2015. A discussion paper was released in September 2016. The paper proposed various options that could provide a rail link to the airport, some of which are or are likely to be metro lines. The metro options are:

The paper also suggested two other potential metro projects: a new line between the Sydney CBD and Parramatta via Five Dock and Sydney Olympic Park and conversion of a section of the T2 Airport Line between the CBD and Revesby via the existing airport. The CBD to Parramatta line was announced as an official project of the New South Wales Government in November 2016.
