CATENARY FREE SOLUTIONS Key References Technical Object – Catenary free solutions SUSTAINABLE SUSTAINABLE SOLUTIONS SOLUTIONS Key references NICE LRT The planned second tramway line in Nice, due to start up in phases in 2018 and 2019, features a line powered without overhead catenaries, using ground-level flash-charging. It is a new technology developed by Alstom combining ground-based static charging with on-board energy storage (supercapacitors). Small power supply units, fed by grids connected to sub-stations, are installed at each stop. It only takes between 10 and 30 seconds to charge the vehicle. © Egis - Cédrick CHATENET LUXEMBOURG LRT The Luxembourg tramway project, scheduled to commence revenue service in 2017, includes a 3.6 km section without overhead catenaries. The flash charging system used is based on a technology developed by CAF. The on-board energy reserve is made up of supercapacitors combined with a battery: it charges at stations through a third rail in the ground. The power supply equipment is installed in a trunking close to the platform. © Egis AVP © Egis - Odile GRIMBERT ANGERS LRT The Angers tramway project, planned to start up in 2022, will use Alstom’s new generation CATENARY FREE SOLUTIONS APS system. This choice was made specifically due to requirements in respect of vehicle compatibility, as some sections run on the same tracks as the first line which is already fitted with Alstom’s APS system.

In the aim of maintaining the high aesthetic quality of these city centres and also complying with regulations, technological progress has today made it possible to dispense with Overhead Line Equipment (OLE), where previously an OLE was the only option for tramway operation.

RCS Versailles 702027376 - February 2017 Technical Object – Catenary free solutions A RANGE OF AVAILABLE SYSTEMS FLASH CHARGING The rolling stock is fitted with an on-board energy storage facility offering two benefits: catenary-free power supply and energy savings thanks to brake energy regeneration. The tramway charges at a standstill (often at a tramway stop) and can run autonomously as far as the next charging point (the next station). Energy can be captured: • through overhead line sections (usually located in tram stop) • through the ground. CONTINUOUS GROUND-LEVEL POWER SUPPLY 3 MAIN TYPES OF SOLUTION EMBEDDED POWER RAIL A ground-level power rail embedded in the tramway platform MAGNETIC INDUCTION Electrical transmission by induction. Embedded into the infrastructure, a primary circuit creates a magnetic field, whilst a secondary circuit on board transforms this magnetic field into electricity to power the tramway. GROUND-LEVEL CONTACT LINE Small magnetised sections crowned with a series of steel plates are embedded into the platform, between the rails. The rolling stock charges through these sections using retractable collector shoes..

  • Current Collector for Heavy Vehicles on Electrified Roads: Field Tests
    Journal of Asian Electric Vehicles, Volume 14, Number 1, June 2016 Current Collector for Heavy Vehicles on Electrified Roads: Field Tests Mohamad Aldammad 1, Anani Ananiev 2, and Ivan Kalaykov 3 1 Center for Applied Autonomous Sensor Systems, Örebro University, [email protected] 2 Center for Applied Autonomous Sensor Systems, Örebro University, [email protected] 3 Center for Applied Autonomous Sensor Systems, Örebro University, [email protected] Abstract We present the field tests and measurements performed on a novel current collector manipulator to be mounted beneath a heavy vehicle to collect electric power from road embedded power lines. We describe the concept of the Electric Road System (ERS) test track being used and give an overview of the test vehicle for testing the cur- rent collection. The emphasis is on the field tests and measurements to evaluate both the vertical accelerations that the manipulator’s end-effector is subject to during operation and the performance of the detection and tracking of the power line. Keywords current collector, electrified road, hybrid electric vehi- cle, electric road system, field test 1. INTRODUCTION The tendency to replace the fossil fuels used by vehi- cles with electrical energy nowadays is clearly identi- fied worldwide. While the solution of storing electrical energy in batteries for small vehicles seems to be rela- tively effective, large vehicles like trucks and buses require a non-realistic large amount of batteries when driving to distant destinations. Therefore, transfer- ring electricity continuously to vehicles while driving Fig. 1 The developed current collector prototype, seems to be the solution [Ranch, 2010] by equipping taken from Aldammad et al.

  • Competitive Tendering of Rail Services EUROPEAN CONFERENCE of MINISTERS of TRANSPORT (ECMT)
    Competitive EUROPEAN CONFERENCE OF MINISTERS OF TRANSPORT Tendering of Rail Competitive tendering Services provides a way to introduce Competitive competition to railways whilst preserving an integrated network of services. It has been used for freight Tendering railways in some countries but is particularly attractive for passenger networks when subsidised services make competition of Rail between trains serving the same routes difficult or impossible to organise. Services Governments promote competition in railways to Competitive Tendering reduce costs, not least to the tax payer, and to improve levels of service to customers. Concessions are also designed to bring much needed private capital into the rail industry. The success of competitive tendering in achieving these outcomes depends critically on the way risks are assigned between the government and private train operators. It also depends on the transparency and durability of the regulatory framework established to protect both the public interest and the interests of concession holders, and on the incentives created by franchise agreements. This report examines experience to date from around the world in competitively tendering rail services. It seeks to draw lessons for effective design of concessions and regulation from both of the successful and less successful cases examined. The work RailServices is based on detailed examinations by leading experts of the experience of passenger rail concessions in the United Kingdom, Australia, Germany, Sweden and the Netherlands.
