Metros and Marshrutkas – taking a ride in Tbilisi: part 1

Posted on 31 August, 2019 by

Recently I had the privilege of spending five weeks in Georgia helping my wife with an art installation. I spent most of my time in Tbilisi on my second visit to this sometimes chaotic but always interesting city which always feels a bit bigger than its population of 1.2 million people. Few people have visited Georgia or its capital, whose transport systems present an interesting contrast to those in Australian cities. It offers some interesting perspectives on transport planning, so in this two-part series I’ll take a look at the city’s urban structure and how people get around it.

The city and its context

It’s hard to understand how Tbilisi works from a transport perspective without knowing something about how the city’s structure evolved. This is closely intertwined with Georgia’s complex history and its current geopolitical status. Both are way too complicated to describe here, but the country along with its neighbours Armenia and Azerbaijan make up the Caucasus and form a major crossroad between Europe and Asia. Not surprisingly Georgia’s location is a key factor in the country’s turbulent and often violent past.

Sydney Metro Observations

Posted on 6 June, 2019 by

Last week I joined the thousands of people who tried out the new Sydney Metro Northwest. I was going to say half-million people, but the total patronage for the first week of operation of over 546,000 obviously includes return and repeat trips. Still, this is an impressive figure, and even if the first day’s patronage (when travel was free) is taken out, average daily use for the working week was nearly 80,000.

I started my trip by taking a train from the line’s current eastern terminus at Chatswood to the final station in the northwest, at Tallawong. I then retraced my journey in stages, stopping at Rouse Hill, Norwest, Hills Showground and Castle Hill before returning to Chatswood. I was trying not just to get a sense of how the new line is working but also its relationship to the centres and communities along the corridor.

The trains

I’ve described the trains in more detail previously and I’ll revisit them in a future post, but in summary there are 22 six-car 132-metre long trains with 378 seats and a total capacity of 1,100 passengers. These have been manufactured in India by Alstom and are a variant of their Metropolis model.

The trains are energised at 1500 VDC from overhead catenary and are driverless, with operations overseen from a control centre near Tallawong where they are stabled. There are three doors per carriage side with 100% longitudinal seating and spaces for wheelchairs, prams and bikes.

Update: Sydney West Metro station plans firm in NSW election refresh

Posted on 6 March, 2019 by

It’s always easy to know when there’s an election on the way in Australia, especially in NSW, as all parties commit to new projects big and small. Top of the list are new infrastructure projects – hospitals, roads, and, increasingly, public transport – with their seductive promise of a shiny new future, ushered in by ribbon-cutting politicians.

But what if you are in government and have already started planning or constructing several large infrastructure projects, or you are in opposition trying to differentiate yourself while supporting at least some of the government’s proposals? Well, the next best thing to a new project is to “refresh” an already-announced one, for example by proclaiming that extra funding has been earmarked for it, that work will begin sooner, or that it will be “fast-tracked” – even if the project remains largely unchanged.

Recent announcements about the Sydney West Metro by both major political parties in the run-up to the 2019 state election provide excellent examples. A few weeks ago NSW Opposition Leader Michael Daley’s committed to spend $8 billion to “fast-track” the planned line. In the last couple of days the government responded, with the NSW Premier Gladys Berejiklian and Transport Minister Andrew Constance announcing that $6.4 billion would be set aside for the project and that construction will begin a year earlier than previously planned, in 2020. The premier also committed to reducing journey times between Parramatta and the city via the metro to around 20 minutes.

Despite all these promises it is unlikely that the project will be completed significantly earlier than 2028 – and neither the government of the opposition’s funding announcements will be nearly enough to complete the metro, given its $16 billion estimated cost. However, the announcement did provide more details regarding the government’s proposed route and preferred station locations, coming shortly after the Sydney Morning Herald’s documentation of the sites of intensive geotechnical investigations for the project and my most recent article which used this information to try to assess the most probable corridor.

While they have both refreshed their commitments to the project, the announcements mean there is now some differentiation between the parties in their approach which have some interesting implications.

Sydney Metro West geotech digging reveals potential stations – including a new “super Central”

Posted on 26 February, 2019 by

In 2018 I published a series of articles speculating on the likely route and station locations for the proposed Sydney West Metro. In the final article I concentrated on the CBD, commenting that geotechnical investigations for the project may provide some clues regarding potential station sites.

That work has continued, and now the Sydney Morning Herald has mapped many of the locations where geotech activity has taken place, revealing areas of concentrated investigation along the route. Meanwhile the Minister for Transport has indicated that there will be a maximum of nine stations.

While there have been no formal announcements regarding specific locations, the options seem to be narrowing. They suggest that my previous comment that Martin Place station could become the “new” Sydney Central could well be an understatement, with an underground walkway set to provide a potential corridor across the CBD, potentially linking up to five CBD metro and rail stations.

New NSW regional train fleet – a solid choice or missed opportunity?

Posted on 16 February, 2019 by

In signing a $1.26 billion contract with the Momentum Trains consortium for a new regional train fleet to be operated by NSW TrainLink the NSW Government seems to have learnt a few things from its chastening experience in selecting Hyundai Rotem’s offering to replace the intercity trains.

As part of the deal Spanish manufacturer CAF has been contracted to supply 29 trains based on its Civity platform. Unlike the intercity fleet, these trains will involve some local manufacture and assembly and will be maintained in rural NSW, with the bulk of the remainder of the $2.8 billion contract covering a new service facility to be located in Dubbo and maintenance of the trains for 15 years.

The government also appears to have avoided two other key aspects of its mishandling of the intercity trains agreement – at 2.88m width, the regional trains do not appear to require any major changes to rail infrastructure, and unlike the unpopular fixed seats in the intercity trains, seating in the regional trains will be reversible.

CAF also seems to have had a lot more experience in manufacturing the train it is contracted to provide than its Korean counterpart has had with making double-deck intercity trains. However, key questions remain – are the new regional trains going to be the best ones for the job and will the new fleet support the network’s future development?

NSW High-Speed Rail: following Victoria’s example?

Posted on 17 December, 2018 by

The announcement by NSW Premier Gladys Berejiklian that the NSW government “would start work on a fast rail network in the next term of government” has already been criticised as being a repeat reading from a very hackneyed script.

True to form, the announcement was made less than four months out from an election by a government fearful of losing rural and regional seats. We all know the storyline – a government announces a High-Speed Rail (HSR) study with great fanfare or a private sector group promotes its own proposal for an HSR line. There is a bit of media coverage, route options are debated, and experts are wheeled out to proffer their opinions. Then a few months later – and in the case of government-led proposals, usually after an election – the proposal is shelved, invariably on cost grounds.

Despite the cynicism there are some worthwhile aspects of the approach the NSW government is taking this time round which are worth exploring. One of these is the similarities with the successful regional rail strategy adopted by its Victorian counterpart.

Bradfield, 75 years on – part 5: using Bradfield’s abandoned tunnels – trains, trams or tourism?

Posted on 3 October, 2018 by

I had intended to write a postscript to my series on the ideas of the engineer John Bradfield and their impact on Sydney in commemoration of the recent 75th anniversary of his death on 23 September 1943, but the NSW Government has, in a sense, beaten me to it.

Recently the government announced plans to transform the abandoned tunnels and platforms at St James Station which Bradfield constructed into an entertainment and tourism precinct housing bars, restaurants, shops or galleries, all occupying 6,000 square metres of underground space. This announcement provides a coda to the last article in my series which touched on the abandoned tunnels in discussing Bradfield’s plans for what was effectively a “missing metro” through Sydney’s inner suburbs.

The tunnels formed a key component of Bradfield’s plans. In this light is the announcement by NSW Transport Minister Andrew Constance the wise recycling of redundant assets to encourage tourism, or a short-sighted takeover of valuable public transport infrastructure? It’s worth taking a look at why the tunnels were built, what the government is proposing to do with them and the potential, if any, for their use as transport corridors.

What was Bradfield planning?

Mr Constance states that “the platforms and tunnels were intended to link the Eastern Suburbs with the Northern Beaches but the plans were never completed”. This is incorrect.

Bradfield may have changed his ideas a few times, but it was clearly the lines across the Harbour Bridge that were always intended to prove a northern beaches link – not the tunnels at St James. In fact, while he proposed an interchange, Bradfield never planned a direct connection between his eastern suburbs and northern beaches lines.

Instead, as I described in more detail in my last article, the St James tunnels were intended to provide an interchange between the City Circle and Bradfield’s planned line which would have run to both the eastern and the western suburbs. Unlike the extra platforms at Town Hall, the additional infrastructure would not only have allowed passengers to interchange, but also would have permitted trains to transfer from the eastern suburbs line to the City Circle, and vice versa.
