Design Engineering Having worked in various rail projects of India (Delhi, Bangalore,Kochi,) and across different countries Hong Kong,Taiwan, Sydney, Mexico projects. • Guaranteed short lead-time delivery to achieve service date targets 1. High-resolution train location determination. • Reliable operations from day one to ensure passenger satisfaction • Automated operations & easy maintenance to reduce operating costs 3. Train borne and wayside processors capable of implementing Automatic Train Protection (ATP) functions, as well as optional Automatic Train Operation (ATO) and Automatic Train Supervision (ATS) functions CBTC was developed to address a wide market and increase competitively. What is Moving Block technology? – • • • • Automatic Protection (AP) is the mechanism ensuring the safety of trains on its railway. It works like a “bubble around the train”; it should not be entered by any object – typically other trains. Thank to the AP, Moving Block technology is possible. Moving Block is the capability to protect trains against collision with other train by knowing the part of the line free of any protection rather than by using static railway portions (blocks) that may be occupied by at most one train (this is Block Mode). Moving Block is based on the concept of End of Authority (EOA). Grade of Automation (GOA)- Different grades of automation are defined depending on how the following functions are carried out: • Train stop at platforms www.railanalysis.com Optimized train speeds and line capacity to reduce costs and to improve passenger comfort As defined in the IEEE 1474 standard, a Communication Based Train Control system is a continuous, automatic train control system using : 2. Continuous, high-capacity, bidirectional train-to-wayside data communications Mr. Chandan Kumar Train start Doors command optional for Present Case Operation in degraded condition Moving Block Use of standard technology (Network architecture) Centralized Architecture (less equipments) Generic Solution, Plat forming SERVICES & FUNCTIONS SAFETY IS KEY: • Passengers onboard (collision, derailment) • Passengers on platform (PSD) • ‘Fall back’ system in case of failure to primary CBTC system • Systems are SIL4 according to EN 50129 and compliant with EN 50121 • Conforms to IEEE Standards 1474.1 and 1474.2 • Train control network complies with the IEEE 802.3 Standard PERFORMANCE • • • • • • • • High availability & reliability Moving Block => headway improvement Faster PSD management Continuous Regulation Faster route release energy saving More automated data preparation and validation Less tests on site and more tests in factory OPERATION Supervision : • • • Accurate train tracking Centralized operation of a line Automatic and continuous regulation Driving : • • • Driverless or driver operation Energy saving Rolling 7F67G&W72&VGV7FFV6R( 6VG&ƗVBFV6R7WW'f6wwr&Ǘ626
