ATO over ETCS

Background

ETCS provides safety & worldwide interoperability BUT major challenges for Main Line Operators are:

to improve the performance and capacity of lines

to reduce operating cost

Automatic Train Operation (ATO) is proven in Urban application

There is a great variety of train and infrastructure fitment

Main Line application is more complex

An interoperable ATO over ETCS has only recently been requested (MoU 37b).

What is ATO over ETCS?

Automatic driving of the train to meet the timetable in the

most energy efficient way.

ATO is an add-on which complements ETCS

There is no safety in ATO (Protection is done by ETCS)

ATO is only available in ETCS Full Supervision mode

ATO-OB with ETCS on-board application (e.g. safe braking curves);

ATO-OB with Train interface;

ATO Impact on ETCS Specs

Additional messages required for the track/train (ETCS as

postman)

ATO traction cut-off when ETCS is not in FS

Additional icons and text indications on the DMI

Suppression of warning indication when ATO is engaged

This will require a compatible update to ERTMS Baseline 3

(M_Version 2.y)

Non fitted ATO trains can ignore ATO messages
