Introduction Automation in Main Line Railways Metro full automation is a reality for years 70 fully automated lines in 40 cities in 2017 Complex full automation with protected environment Mainlines automation under progress autonomous ATO in service, ATO over ETCS in deployment China Intercity since 2016 Shift2Rail IP2 in progress to raise from GoA2 to GoA4 Tramways DAS/ADAS Experimentation and deployment Freight & Mining Locomotive Auto pilot, trip optimizer, remote control 3
Infrabel simulation studies Local train Energy saving : % gain of ATO versus Manual Driving ATO gain Driver 1 Driver 2 Driver 4 Driver 3 Better than ATO, but 4
Infrabel simulation studies Local train But good driver in Energy Saving was also Too Late Energy saving Traffic regularity 5 Only ATO gives both Energy Saving and Regularity
Infrabel simulation studies Local train Speed profiles Different driver behaviours on same journey Cumulated Energy Consumption lead to potential consumption of up to 42% 6
A practical example : ATO for Paris RER-A Line with 1,2 million passengers per day One central section and five branches Double-deck trains carry more than 1300 persons at 100 km/h through the central sections for a 2 minute headway 7
Paris RER-A Operation challenges But both regularity and performance need to be improved ATO 8
Paris RER-A: Alstom ATO project on a conventional signalling System developed by Alstom in a 20M contract for RATP ATO (GOA2) put in operation for RATP from April 2017 Controlling double sets of 5 car double-deck MI09 trains or previous generation MI2N First trains successfully in operation The whole fleet will be progressively put into service until end of 2018. 9
Paris RER-A : ATO Mode In automatic mode, the driver operates the doors and starts the train. The operation then is fully managed by the ATO until the next station taking account of : Track characteristics Train characteristics (traction and braking performance) Signalling information (speed limits, signals, stop points) ATO equipment is installed in the driving cabs. Additional fixed equipment such as balises are installed on the track where the existing SACEM balises are not able to provide the required stopping accuracy. 10
Paris RER-A : System architecture Automatic driver system has been added to existing SACEM ATP Rolling Stock 11
Paris RER-A Project minimizing disruption risks Alstom developed a project-specific virtual testing platform including a complete system with simulator to accelerate the system maturity growth. Extended simulation to the whole line instead of the standard model with two stations and the associated interstation route. RATP provided the existing SACEM equipment (hardware and software) for the virtual test benches. Alstom simulator sent SACEM information on train movement. SACEM communicated with the ATO via a realistic interface. This allowed a swift and realistic validation, resulting in successful dynamic tests. This flexible approach enabled us to reach project maturity ahead of schedule, enabling RATP to quickly deploy shadow-running a newlyequipped ATO train integrated into the operational fleet. 12
Paris RER-A : ATO operational objectives The solution will drive service regularity Reduce journey times by approximately 3min 45sec on an average journey from Vincennes to La Défense An increase in commercial speed of 5 km/h. Will also avoid delays on the difficult central section maximising and standardising the train operational speed based on the real-time distance between trains The specification required the ATO-equipped trains to operate at constant speed with a 4% margin ATO is able to adjust speed to recover from delays 13
Another example China s regional Intercity lines project Intercity project covers 3 Megalopoles & 10 city clusters ~17 000 km / ~5 000 trains New regional networks to give the capability to join each point of the identified region in less than one hour (vs 3 hours today) New train s types specific for Intercity operations Customer requiring ATO with CTCS-2 ATP 14
Alstom participation in the ATO project Alstom doing a joint development of the ATO system with Casco JV Since March 2016 : Successful entering in passenger revenue service of one CRH6-200 km/h train equipped with Alstom/ Casco Intercity solution Running on the Dongguan/Huizhou line + Zhaoqing to Foshan westline (suburb of Guangzhou in Guangdong province) Key Milestones : run 250 000 km to get final license of on-board CTCS-2 ATP, prior the first commercial contracts 15
ERTMS and ATO ERTMS basic functional architecture ERTMS 16
ERTMS and ATO ATO over ETCS ERTMS ATO over ETCS FIS 17
ATO over ETCS and Shift2Rail IP2 ML ATO V1.x -> (GoA 2) ML ATO V2.x -> GoA 3 and GoA 4 18
Conclusion ATO for main line railways brings benefits: especially on capacity, smooth riding, energy savings then on customer satisfaction and operation + maintenance costs ATO GoA2 for main line railways is here: Paris RER-A, China Intercity Projects such as Shift2Rail will bring more, up to GoA 3-4 with e.g. moving block, train positioning, train integrity new sorts of control centres 19
