| Toronto Pearson International Airport; Toronto (Canada) | | Safe airport link | UL-Approved BETA Low Voltage Line Protection Switchgear is Onboard Toronto's Cable Liner Shuttle
Since 2006, passengers at the Pearson International Airport of Toronto, Canada, can enjoy the Cable Liner Shuttle as a high-speed and comfortable link between the new T1 terminal building, the T3 terminal and the parking area. As a part of the electrical equipment of the mass transit train that has been jointly developed by Siemens and the Austrian company Doppelmayr Cable Car GmbH & Co. (DCC), Beta low-voltage line protection switchgear ensures the safety of people, equipment and motors.
The increasing demand for mobility at airports, but also in shopping malls or theme parks requires advanced solutions for passenger transportation. Automatic People Movers (APM) keep demonstrating their value as a perfect solution. The APM system from Siemens Industrial Solutions and Services (I&S) and Doppelmayr Cable Car GmbH (DCC), Wolfurt, Austria, is a cable-drawn, fully automatic Cable Liner Shuttle. It is used where many people need a fast, safe and comfortable means of transport over short distances. The attractive mass transit solution appeals by its fully automatic driverless operation, short waiting times for passengers, easy system integration as well as high availability and safety. The emission-free and quiet Cable Liner Shuttles are highly environmentally compatible.An ambitious projectWith over 28 million passengers annually, the Toronto Pearson International Airport is Canada's largest airport. The Cable Liner Shuttle is part of a comprehensive extension plan. The Center of Competence of Siemens I&S, which is based in Innsbruck (Austria), supplied the entire power supply system for the new shuttle as well as the drive technology and the Automatic Train Control system and provided engineering, installation and commissioning. The project was completed in late 2005.Power supply package includes Beta low voltage line protectionThe electrical systems and equipment from Siemens are designed for worldwide use, which includes the North American market. For the electrical power distribution and automation system of the Cable Liner, Siemens supplied the low voltage switchgear, 3-phase motors, frequency converters, drives, switching cabinets as well a Beta low voltage circuit protection. The Automatic Train Control System is based on a complex SIMATIC controller. The use of more than 300 protection switches 5SY6 ensures the safety of the installation as well as of people and motors. This is complemented by 700 line protection switches from the high-performance program 5SY4 as well as over 800 control switches for line protection switches. The special devices for 5 and 15 A were specifically used for the Northern American market. The line protection switches are approved to UL 1077 and CSA 22.2 No. 235-M 89 and designed for use as "supplementary protectors" up to AC 277V and AC 480V. They also meet the relevant requirements for railway applications. The 5SY line protection switches are primarily used to protect cables and lines against overload and short-circuit. Under certain conditions, they also provide protection against hazardous body currents in case of excessive contact voltages as a result of insulation faults. Due to the predefined design currents, the line protection switches also provide motor protection. For use in installations, the line protection switches are complemented by freely mountable additional components such as auxiliary switches, fault signal switches, shunt trips, undervoltage releases, RCCB modules and freely mountable accessories such as busbar systems and mounting hardware.With 43 km/h to the destinationAt Toronto airport, two parallel, independent shuttle systems were built, each with a length of 1423 meters and running at 43 km/h. Each shuttle train consists of six individual cars that are drawn by a cable. The system has a transport capacity of 2164 persons per hour per direction. The shuttle travel time is about three and a half minutes. The partially extreme climatic conditions of the Canadian winter cannot interfere with train operations. The snow will not stay on the elevated steel construction that forms the track. Since the train is drawn by cable, operation can continue even in snow and freezing rain.The Cable Liner: A shuttle system with a futureIn addition to Toronto airport, Siemens and DCC equipped the international airport of Birmingham in the United Kingdom with the Sky Rail Shuttle. Another system, the "Mandalay Bay Tram", is already successful running in Las Vegas, USA, since 1999. This has transported about 100 million passengers since April 1999 - with a system availability of 99.6 per cent! The joint development of DCC and Siemens, the Cable Liner Shuttle, has successfully established itself in the market. Additional major and attractive follow-up projects in the North American and Asian regions are planned.Doppelmayr Cable CarThe DCC Doppelmayr Cable Car GmbH & Co. with headquarters in Wolfurt (Vorarlberg, Austria) is a subsidiary of Doppelmayr, a company that was founded in 1892 as a manufacturer and vendor of cable cars, lifts and other transportation systems. DCC further developed the technology of cable-drawn railway systems into an advanced APM system for urban mass transit and has been maintaining a long working relationship with Siemens AG in this field.
