Defined in IEC 62267 – Railway applications – Automated Urban Guided
Transport (AUGT) – Safety Requirements
What is Grade of Automation?


Increasing Levels of Automation with CBTC – Dave Keevill, P.Eng.
IRSE Seminar 2016 – CBTC and Beyond
Specified Grades of Automation (GOAs)

GOA 0: Manual operation with no automatic train protection

GOA 1: Manual operation with automatic train protection (like PTC)

GOA 2: Semi-automatic train operation (STO)

GOA 3: Driverless train operation (DTO)

GOA 4: Unattended train operation (UTO)
Other definitions:

ATC = Automatic Train Control, comprising:
▫ ATP = Automatic Train Protection (safety)
▫ ATO = Automatic Train Operation
▫ ATS = Automatic Train Supervision

Train Operator = Driver

Attendant (not necessarily located in the control cab)

GOA0 – Manual Driving, no ATP or ATO

GOA 0: Manual operation with no automatic train protection
▫ Safety and efficiency of train movements are fully under the control of the
Train Operator
▫ Movement authority, including route locking and maximum speeds, may be granted by a variety of means, including:
◦ Wayside signals and line-of-sight conditions
◦ Permanent operating rules
◦ Verbal instructions in person or by radio voice communications

GOA 1: Manual operation with automatic train protection

GOA 2: Semi-automatic train operation (STO)

GOA 3: Driverless train operation (DTO)

GOA 4: Unattended train operation (UTO)

GOA1 – Manual Driving with ATP

GOA 0: Manual operation with no automatic train protection

GOA 1: Manual operation with automatic train protection
▫ ATP protects train from specified hazards, typically by applying brakes to a stop
▫ ATP may provide protections associated with any combination of
(refer to IEEE 1474.1):
◦ Route interlocking, train spacing, end-of-line, travel against the authorized direction
◦ Train integrity, overspeed, door operation and travel in the vicinity of trackside work crews
▫ Train Operator is responsible to command train acceleration, deceleration and door opening/closing, and to monitor track conditions ahead of the train

GOA 2: Semi-automatic train operation (STO)

GOA 3: Driverless train operation (DTO)

GOA 4: Unattended train operation (UTO)
6

GOA2 – ATO with Driver in the Control Cab

GOA 0: Manual operation with no automatic train protection

GOA 1: Manual operation with automatic train protection

GOA 2: Semi-automatic train operation (STO)
▫ System provides full ATP and ATO, with a Train Operator stationed at the control cab
▫ Train Operator monitors trackside conditions ahead of the train and typically triggers door closure and train departure

GOA 3: Driverless train operation (DTO)

GOA 4: Unattended train operation (UTO)
7

GOA3 – ATO with Roving Attendant

GOA 0: Manual operation with no automatic train protection

GOA 1: Manual operation with automatic train protection

GOA 2: Semi-automatic train operation (STO)

GOA 3: Driverless train operation (DTO)
▫ System provides full ATO and ATP
▫ Attendant (aka Train Captain) is stationed on-board the train to support recovery operations and attend to passengers as required
▫ As the Attendant is free to move about the train, not necessarily available at the control cab to detect the presence of hazards ahead of the train
▫ These hazards must either be rendered sufficiently remote to preclude the need for Train Operator vigilance at the control cab or be detected by supplementary systems

GOA 4: Unattended train operation (UTO)
8

GOA4 – ATO Unattended

GOA 0: Manual operation with no automatic train protection

GOA 1: Manual operation with automatic train protection

GOA 2: Semi-automatic train operation (STO)

GOA 3: Driverless train operation (DTO)

GOA 4: Unattended train operation (UTO)
▫ No driver or attendant required on-board the train for normal operation
▫ Rolling stock does not require a control cab, per se: a hostling panel is deemed sufficient for rare manual movements
▫ System reliability needs to be sufficiently high to preclude the need for
Train Operator intervention, except for extremely low probability failures
▫ Manual movements typically limited to maintenance and storage facilities, or for failure recovery
▫ May be applied by territory
(e.g. full system, only mainline, only core areas, only reversal locations)
