What is ATO?

• Automatic driving of the train to meet the (real time)
• perational 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

• 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

More Trains Better Connections Greater Reliability

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)

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

• n-board)

▪

Packet Switching communication only

▪

Separate ATO communication session

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.

14

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
