What is ATO? • Automatic driving of the train to meet the (real time) operational timetable in the most energy efficient way. • Grades of Automation: • GoA 1 - Manual Train Operation (including C-DAS) • GoA 2 - Driver-attended Automatic Train Operation. • GoA 3 - Driverless Train Operation • GoA 4 - Unattended Train Operation 5

Benefits of ATO More Better Greater Trains Connections Reliability • Increased capacity on the existing network • Increased energy efficiency • Improved recovery from disruption (better punctuality) • Reduced operational costs • Reduced wear and tear due to reduced traction/braking and overall lower running speeds • Train regulated to real time operational data, fewer restrictive signals (and less stopping of the train) • Train stops automatically in station, no missed stations • Support for improved conflict resolutions (TMS) • Improved passenger comfort 6

Key requirements for the ATO over ETCS System There are 4 key areas: • Legislation Interoperability (ATO in the CCS TSI) ▪ Optional function (Mandatory specifications) ▪ • Levels & Modes C-DAS system in GoA1 ▪ ATO/C-DAS shall be possible in ETCS Level 1, 2 & 3 ▪ New ETCS mode (AD mode) ▪ 7 7

Key requirements for the ATO over ETCS System • Integrated DMI Integrating ATO/C-DAS display with the ETCS ▪ DMI No additional train data entry for ATO ▪ • Architecture Integrated ATO/ETCS on-board ▪ Fully separate ATO on-board (FFFIS ATO/ETCS ▪ on-board) Packet Switching communication only ▪ Separate ATO communication session ▪ 8 8

Thameslink/Crossrail ATO Lessons Learnt Timetable Construction Current 30 second timing resolution introduces challenges. ▪ For ATO to work effectively requires more detailed timetable ▪ information & ideally real time updates Definition, location & alignment of timing points between ▪ timetable production systems and ETCS/ATO balise groups. Door Opening and Door Closing Need to be considered from an operational perspective ▪ Train dispatch arrangements Alignment of driver dispatch procedures with timetable ▪ departure times. 13

Thameslink/Crossrail ATO Lessons Learnt Station Stopping Positions Thameslink uses a ‘centre line’ stopping strategy for ▪ variable length trains Crossrail will operate with platform screen doors and ▪ fixed length trains Transition arrangements need to be considered Relationship between ETCS and ATO transitions ▪ Storage and update of the ATO Track Data Base. On-board data base as on Thameslink ▪ Dynamic update of train from trackside data base as in ▪ European – final choice for Interoperable specifications. Train propulsion and braking systems interface Optimised off site but required fine tuning ▪ 14
