Metro News: Sydney’s unique contract design underpins train performance

About half of Sydney’s suburban fleet has been replaced, in a $3.5Bn Public-Private Partnership (PPP). It is the largest passenger fleet procurement in Australian history, replacing non-air-conditioned rolling stock and providing for future growth. This required a robust commercial and operational framework for a contract term which exceeds 30 years.

In 2004, the NSW railway operator RailCorp took an innovative approach. At the very beginning of the procurement process, rather than at the typical point of signing contracts, it appointed a project delivery leader to establish an integrated commercial, operational, technical and delivery management team. This has been a main contributor to a successful PPP contract, which was structured to underpin safety, quality control, and reliability over 30 years. This specialist team provided input into the final contract design and performance specifications based on previous new fleet deployments.  The delivery team has also proved invaluable in overseeing implementation, from the build phase through to passenger service.

One of the unique features of this PPP contract is that it does not contain typical liquidated damages penalties (although, the separate contract between the consortium’s manufacturer and TLS provider does include liquidated damages).  Instead, the contract relies on several ‘incentivising’ payment mechanisms aligned to drive desired performance outcomes. The payment system promotes behaviour that reduces the need for the NSW railways operator to actively enforce the contract. At the heart of the contract are performance-based payments that require 72 of the 78 trains to be made available for passenger service each day. Until the trains are provided and available, Sydney RailCorp makes no payment to Reliance Rail for them.

Another significant factor has been a comprehensive operational-readiness programme. This involved stakeholder and expert consultation during the development phase, to integrate contract requirements with the operational requirements of the operating railway.  This readiness programme involved over 20 enabling projects including people & change management initiatives to support operational efficiencies and the deployment of the new fleet.

These measures have led to one of the smoothest new fleet deployments in the history of NSW. In just over 14 months, 14 eight-car double deck trains (which include 1 spare set) have been introduced into passenger service and accumulated more than a million kilometres in service.  Feedback and internal surveys indicate customers rate the Waratah train as the best train for performance and comfort amongst all existing fleet, including other recent fleet acquisitions. Similarly feedback from crew about the Waratah trains has been positive with train performance in line with expectations.

Metro News: Metro Rio’s “Pit Stop/Bogie Drop” Replacement System

Metro Rio has recently begun using an innovative system for bogie replacement. In the 1980s, Metro Rio rolling stock’s bogies were replaced using four hydraulic jacks (15 tons capacity each) to lift a 42 tonne metro car and drop the bogie. This equipment was obsolete, unreliable and sometimes unsafe. Furthermore, there was no feature to synchronize the rise/descent of the 4 jacks, thus making it a complex operation. These factors lead Metro Rio to develop a different system to replace bogies using a lifting platform coupled to two hydraulic jacks. This system required the maintenance team to uncouple the specific car from the rest of the train to replace bogies, and this single car could only be moved with a maintenance vehicle (as there is no third rail inside the rolling stock maintenance area).

Recently Metro Rio has acquired a new fleet (19 trains with 6 cars) which uses semi-permanent couplings. The process of uncoupling these is time-consuming, making the current bogie replacement process not very effective. That led Metro Rio to design and construct a new bogie replacement system.

The new bogie replacement system is called “pit stop.” A complete train can get into this system without any maintenance vehicle support as the bogie drop facility is located in a single dedicated track with power supply. The bogie is removed without having to uncouple the cars, reducing the downtime considerably. The “pit stop/bogie drop” is particularly useful when a bogie failure happens during service hours and is necessary to get the train back into revenue operation very quickly.

Metro News: Improving service through automation in Paris

The automation of Line 1, the Paris Métro’s oldest and most popular line, with 725,000 passengers per day, has been achieved without any major interruption to service. This technological change has become necessary to deal with the steady increase in passenger traffic.

With the automation, Line 1’s passengers will benefit from a more responsive and regular transport service, ensuring greater safety and comfort. One of the main benefits of automation is the line’s ability to react instantly to an increase in passengers and provide the number of trains required for the optimum operation of the line.

The automation is expected to improve commercial speed by 4% and because fewer trains will be needed for the same headway, will achieve 6% rolling stock savings. The system also has the potential to reduce minimum headway by 20%. Not having a driver’s cab will also increase passenger capacity by 6%, even without any headway improvements.

The installation of platform screen doors on all the lines’ platforms contributes significantly to the smooth running of the line, avoiding interruptions associated with track intrusions, while also enhancing passenger safety. The migration process combined both automatic and manually driven trains on the same line, with all trains automated since January 2013. It is a world first given the importance of the line.

The project to automate line 1, launched in 2004, is part of the huge modernisation programme that RATP will be undertaking over the next twenty years. The project will allow the company to meet growing demand and to satisfy its customers’ expectations in terms of safety, comfort, regularity, flexibility and information, at a time when RATP is seeking ways of anticipating and/or remedying network saturation.

CoMET and Nova News: Introducing Istanbul Ulasim

In 2012 Nova welcomed Istanbul Ulasim to the group. Istanbul is the largest city in Turkey, with a population of 13 million people making 27 million daily trips of which 13% are made by rail.

The rail-based network in Istanbul comprises 8 rail-based lines which include metro, light rail, and tram. The metro lines, M1 (red), M2 (green), M3 (blue( and M4 (pink), are included in the Nova membership. Line M5 (purple) is currently under construction. With the recent opening of the Marmaray tunnel linking M4 (Asian side) with the European side of Istanbul, this metro becomes the world’s first inter-continental metro network.

Metro Facts:

  • 25 million car km in 2012
  • 175 million passenger journeys in 2012
  • 77% customer satisfaction
  • 62% of journeys made using the Akbil smartcard

Istanbul Ulasim will benefit from Nova and CoMET through the ability to share good practices and learn from other fast-growing metros in large cities in South America and Asia.

Metro News: Guangzhou Metro develops new CBTC system

In cooperation with the China Railway Academy of Science and Technology, Guangzhou Metro has successfully developed a new CBTC signaling system which has now passed the scientific and technological achievement appraisal by Guangdong Province, China. This is an important achievement because the number of CBTC systems on offer is currently very limited.

The technical design of the MTC-I CBTC program was finished in 2008, experimental testing was finished in 2009, and field trials were conducted in 2010. Meanwhile, the CBTC system has received third party safety certification by Lloyds, and safety certification of related subsystems including computer-based interlocking system platform, trackside controller subsystem, on-board ATP subsystem, FIMI fail-safe intelligent input and output modules, axle counter (Safety Integrity Level 4) and ATS system(Safety Integrity Level 2). The system uses wireless communication based moving block technology. The achievement of scientific and technological identification and third-party safety certification has enabled the MTC-I CBTC signaling system to move into the engineering application stage.
