2 Rail traffic automation 3 pillars TARGET: Increase capacity and effectives with ensuring same or increasing level of safety TARGET: Elimination of routine operations and computerised support for decision making AVV Train driver + Automatic train operation Train dispatcher + Automatic train route setting GTN Dynamic time table Targeting trains into time slots

4 ATO history in Czech Republic On Czechoslovak Railways, train driving automation started in 1960 s s The main aims were saving of energy for traction and better utilization of track and rolling stock parameters as well as decreasing of driver s workload. ATO testing railcar class M In half of 60 s - first tests with Automatic Train Operation systems (consisting of Speed Regulator, Automatic Target Braking System and Energy Saving System). ATO is not the new technology

5 ATO history in Czech Republic The pilot installations of full (analogue) ATO were under tests in commercial operation Digital solution with analogue interface to the vehicle tested in standard commercial operation 1980 s 1991 ATO test loco (1985) EMU with commercial ATO (1996) Class 470 EMUs equipped with fully digital ATO New EMUs class 471 are equipped with digital ATO during their manufacturing Digital ATO in everyday operation for 25 years

6 ATO type AVV (Automatické Vedení Vlaku) Automation system designed for railway and metro application AVV controls: traction engines brakes (traction, dynamic, pneumatic) On-track orientation: Balises MIB GPS device ETCS balises Safety level SIL 0 / SIL 1

7 ATO type AVV (Automatické Vedení Vlaku) Target braking with accuracy ±0,5m for railway and ±10 cm for metro Control train running to reach next station just in time with minimum consumption of traction energy just-in-time arrival accuracy ±5 sec for railway and ±2 sec for metro energy savings 10-30% CO 2 reduction

8 ATO coverage at CZ railway infrastructure ATO covers 2450 km 25% of CZ network one of most dense in Europe ATO MIB6 type balises 1300 km + ATO GPS localisation 1150 km

9 Refurbished NEW ATO AVV references Class Vehicles / Units ATO sets EMU class E-loco class EMU class EMUs classes 440/640/ DMUs class D-loco class E-loco classes 162, 163, Driving trailers class E-loco class D-loco class % of new and refurbished vehicles and 10% of the whole fleet with ATO GoA2

10 AVV contribution to sustainable transport Example: EMU class 471 fleet - impact on CO 2 emissions Fleet = 83 EMUs with operation availability 85 % Fleet runs 13 millions km per year Most of the operated lines equipped with ATO trackside 200 tons of trainset (incl. passengers) Average energy consumption 35 Watt*hour per ton*km Emission of 1,2 tons CO 2 per 1 MWh Calculating only 15% of energy savings due to AVV Just EMUs class 471 fleet saves about tons of CO 2 /year

11 ATO over ETCS = ideal couple for safe, effective, exact and comfort train operation ATO AVV cooperates with ETCS: Using ETCS information for on-track orientation, Using ETCS static speed profile, converting to dynamic speed profile and its realisation (speed control to run very close to allowed speed / braking curve), Providing interface functions for service braking Easy integration due to no complicated EVC-AVV interaction Lesson: ETCS braking curves are not fully optimised for energy consumption savings

12 ATO over ETCS and safety The ATO AVV itself is SIL 0 or SIL 1 Interface AVV - EVC link is therefore SIL 0 The safety of train running is ensured by ETCS (national ATP/STM) system Successfully operated Lesson: Keeping separated systems will enable future modification and freedom

13 SC = Safe Check SC = Safe Check Driver activities /workload: ETCS w/o AVV ETCS without AVV ETCS with AVV Train driver activity driver ETCS driver AVV ETCS order to depart x control of moving off x x reaching and running Vmax x x braking to speed restriction x x reaching and running Vrestr x x order to increasing of speed x control of moving off x x coasting before stop (with respect to x x arriving "just in time") station entry in restricted speed x SC x SC braking to the platform x x stopping at the platform x x AVV has not affect any function executed by ETCS ETCS + AVV does decrease the working load of driver

14 Future development of ATO - dynamic info Information systems of infrastructure manager ATO track side CTC control centres ATS DOZ + GTN RBC Radio Block Center Electronic interlocking ESA 44 Electronic interlocking ESA 44 ATO on-board ERTMS on-board ATO on-board ERTMS on-board

15 Future development of ATO Deploy ATO technology from single country/projects to European railway network Dynamic information for ATO on-board ATO over ETCS information onto ETCS DMI ATO trackside ATO on-board standardised interface interoperability New ATO functions according Shift2Rail e.g. virtual coupling trains and ETCS L4 ATO GoA4 is ready needed RI adaptation and operation rules

16 A T O S U M M A R Y ATO is matured technology already proved and in everyday operation at Czech railway network for more than 25 years ATO technology is also key element for increasing traffic density as required in EU White paper on transport and as interconnected with ETCS is foundation for further development and deployment of ETCS especially beyond Level 3 ERA together with railway industry, operators and infrastructure managers shall ensure interoperable use of ATO with freedom of choice of technology and implementation Only interoperable ATO will enable wide deployment onto pan European railway network in short future Ing.
