Rail and Metro Innovation Guide 2018www.SmartRailWorld.com13Bombardier have delivered a faster and more efficient driverless train along Kuala Lumpur's new fully automated CityFlo 650 network. Running along the second phase of the new Klang Valley line, passengers can now cross the Malaysian capital in under 90 minutes. This train technology has already been installed in 37 lines worldwide. CityFlo 650 signalling is a CBTC system which makes use of bi-directional radio communication between trains and wayside equipment to control train operation. Trains report their position via radio, and a signalling system provides movement authorities to the trains via a radio link. The new rapid transit will serve from the north-west to the south-east of the city with the line has the potential to remove 160,000 vehicles from the road. Passengers in the capital will enjoy a fast and safe ride over the 51-kilometer line.CityFlo 360 supplied by Bombardier (@Bombardier) is a system for driverless or unattended train operations designed for moving block advanced metro operations and airport people movers. The track to train communication is achieved via a state-of-the-art wireless technology to provide bi-directional communication. The system is used for automatic running of trains on segregated tracks.Gregory Enjalbert, Vice President of Rail Control Solutions Asia Pacific, Bombardier Transportation said, "With the completed KVMRT Line 1 now operating with our driverless CityFlo 650 solution, Bombardier's range of urban transport solutions are increasing mobility for up to 700,000 passengers daily in the Greater Kuala Lumpur area. Along with Bombardier's driverless Innovia metro fleet, which opened on the Kelana Jaya Line just a few months ago, we continue to provide truly integrated mobility for Malaysia, helping the government meet its plan to ensure enjoy a seamless commuter journey by 2030."Bombardier is equipping over 100km of the KVMRT network with its fully-automated signalling technology. The proven solution, in service or delivery on 37 lines worldwide, offers operators like Rapid Rail in Kuala Lumpur, optimised network capacity and heightened responsive traffic management. The modern system, which features a centralised control centre system and advanced radio-based communications, has been achieving high levels of availability since phase one opened in December 2016. Driverless trains operate with a peak-time frequency of less than three and a half-minute intervals and at speeds of just under 100km/h. The new line offers a time-efficient and comfortable journey for passengers to cross the city within 90 minutes.Bombardier has been delivering sustainable transit and rail solutions to Malaysia for more than 20 years. With public rail transportation a key part of Malaysia's economic development programme in the Kuala Lumpur and Klang Valley area, Bombardier is currently delivering its advanced CITYFLO rail control solution for the first two lines of the new, fully-automated and driverless Klang Valley Mass Rapid Transit (MRT) system which will increase connectivity, including in and out of Kuala Lumpur, for an estimated 1.2 million residents.The CBTC solution aiming to "provide truly integrated mobility for Malaysia.""Bombardier's range of urban transport solutions are increasing mobility for up to 700,000 passengers daily in the Greater Kuala Lumpur area."SECTION 2: SIGNALLING AND TRAIN CONTROL

14www.SmartRailWorld.comRail and Metro Innovation Guide 2018With the technological improvement on our tracks, trains passing red signals are at an all-time low. Without a major accident, it has been easier for the industry to maintain constant scrutiny and analysis of data and sustain a focus on where risk needs to be managed, such as at level crossings and the platform-train interface on stations. Improvements by the industry have meant that it's been 17 years since Signals Passed at Danger (SPADs). But now, train accident risks could be lowered even further by using big data to reduce the chances of a train passing a red signal according to the rail industry body RSSB. Thanks to a new online tool, rail companies will be able to harness the power of big data to identify the signals which are most frequently approached at a red signal."The 'Red Aspect Approaches to Signals' (RAATS) tool uses 420 days of train movements provided by Network Rail through its open data initiative and applies complex algorithms to identify where red approaches are happening."The technology has been developed by Rail Safety and Standards Board (RSSB) and the University of Huddersfield. Working in partnership with the RSSB (@RSSB_rail ), Dr Yunshi Zhao and Mr Julian Stow from the University's Institute of Railway Research (IRR) used this data to develop an algorithm giving the number of occasions when a signal is displaying a red aspect. An initial survey of seen signalling areas showed that 3.3% of all approaches were to red signals.To make the next step in risk reduction, rail is now keen to look deeper into the circumstances that cause a SPAD, such as how frequently a signal is approached showing a red aspect and the number of occasions when they have been red when a train is approaching.The 'Red Aspect Approaches to Signals' (RAATS) tool uses 420 days of train movements provided by Network Rail through its open data initiative and applies complex algorithms to identify where red approaches are happening. Results can be broken down by train type, day of the week or time of day and analysis can be carried out on signal groups. Users can interrogate data within the tool or export it to Excel. The RAATS tool was released as a prototype in January, and work is underway to refine it including linking it to live data feeds, before formally launching it later in the year.George Bearfield, RSSB's Director of System Safety and Health, said: "Train accident risk has reduced significantly over the last 20 years, but we don't rest on our laurels and instead seek to make another step change in safety management, and that means looking at underlying causes of incidents. This tool can help us focus attention on signals where SPADs may be more likely. It's proven successful in trials and we hope it will be used to generate new safety and performance insights for rail companies.£5m worth of strategic research between RSSB and IRR has meant that the algorithm behind Raats will now be made freely available online for all train operators in Britain to enable further development of the tool.Red signal faults could be reduced further thanks to Big Data software.SECTION 2: SIGNALLING AND TRAIN CONTROL
