ARS According to Train Path

Interlocking states are mirrored in Base simulation „What is possible in GTN should be possible in

interlocking“

=> Low probability of request rejection by interlocking

Other Automatic Functions

Route cancelation Time synchronization Anticipated / real

departure insertion Train number

insertion, editing Individual point control Line consent request Locking the closed

level crossing

Tasks to Solve

Collision access to some platforms Input information

Temporary speed restrictions• different infrastructure models

– IS IM X GTN Výhled

Exceeded loading rate Waiting times, rolling stock circulations

Interface to Operating Personal

ARS control through JOP X GTN

Possible commands: Editing station / line track Editing dwell / departure time Turning ARS on / off

• train• station• controlled area

Absolute / disposition stop

ARS Behavior

High traffic intelligence => most of routes set without dispatcher intervention

Warning if route cannot be set Dynamic adaptation to dispatchers

commands on JOP ARS with advance

enough time for route cancelation by dispatcher
