PMGI – SIL4 Distributed Interlocking System

Decentralized interlocking system linked to switch operation

PMGI is an innovative signaling system guaranteeing the highest Safety Integrity Level (SIL4), designed for urban transport solutions.
PMGI is an integrated solution for train interlocking and control.

RAIL-MAP key functionality is to allow a distributed signaling provided by a safe cluster of two types of dedicated equipment :

Switch movement control and supervision
Signal lighting control and supervision
Each equipment consists of a generic hardware with a dedicated firmware: Signal Control & Supervision, Switch Control & Supervision
RAIL-MAP can either be expanded alongside the track, or rack mounted in a technical room
The system is designed for use on either existing or new metro or tram lines
