    HURONTARIO LIGHT RAIL TRANSIT PROJECT Welcome Please sign in so we can provide updates and information on future events. metrolinx.com/HurontarioLRT [email protected] @HurontarioLRT WHAT IS THE HURONTARIO LRT PROJECT? The Hurontario Light Rail Transit (LRT) Project will bring 20 kilometres of fast, reliable, rapid transit to the cities of Mississauga and Brampton along the Hurontario corridor. New, modern light rail vehicles will travel in a dedicated right-of-way and serve 22 stops with connections to GO Transit’s Milton and Lakeshore West rail lines, Mississauga MiWay, Brampton Züm, and the Mississauga Transitway. Metrolinx is working in coordination with the cities of Mississauga and Brampton and the Region of Peel to advance the Hurontario LRT project. Preparatory construction is underway. The project is expected to be completed at the end of 2022. The Hurontario LRT project is funded through a $1.4 billion commitment from the Province of Ontario as part of the Moving Ontario Forward plan.

  • 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.

  • Rapid Transit in Toronto Levyrapidtransit.Ca TABLE of CONTENTS
    The Neptis Foundation has collaborated with Edward J. Levy to publish this history of rapid transit proposals for the City of Toronto. Given Neptis’s focus on regional issues, we have supported Levy’s work because it demon- strates clearly that regional rapid transit cannot function eff ectively without a well-designed network at the core of the region. Toronto does not yet have such a network, as you will discover through the maps and historical photographs in this interactive web-book. We hope the material will contribute to ongoing debates on the need to create such a network. This web-book would not been produced without the vital eff orts of Philippa Campsie and Brent Gilliard, who have worked with Mr. Levy over two years to organize, edit, and present the volumes of text and illustrations. 1 Rapid Transit in Toronto levyrapidtransit.ca TABLE OF CONTENTS 6 INTRODUCTION 7 About this Book 9 Edward J.
