01

What urban rail operators need

01
More trains on the
same track

Moving block safely narrows the gap between trains, and the system is designed for a 90-second headway at up to 60 km/h.

02
Safe unattended operation

Onboard ATP/ATO handles speed supervision, automatic driving and precise stopping. GoA 4 unattended operation is also supported.

03
Modernize without closing the line

A staged migration lets legacy and CBTC trains share the track, so passenger service continues during the upgrade.

04
Less trackside equipment

Onboard sensors detect train position from wayside position tags (transponders) and exchange it over radio.

02 · SYSTEM CONFIGURATION

Each train reports where it is. The wayside tells it how far it may go.

Movement authority is recalculated continuously, so the safe distance moves forward as the train ahead advances.

CONTROL CENTER
ATS · Automatic Train Supervision

Timetable, routing, regulation and operator displays

Commands down, train status up
WAYSIDE
Wayside ATP SIL 4

Tracks every train and grants movement authority, 10 to 40 trains per unit

Electronic interlocking SIL 4

Interlocks and controls points and signals according to the route

Position report up, movement authority down, over LTE-R or Wi-Fi
ONBOARD
Onboard ATP/ATO SIL 4

Speed supervision, automatic driving and precise stopping
