Applications

Every conversation
a railway has.

The complete UIC FRMCS v2.1 application catalogue — every box in FIS Figure 2 — implemented symmetrically trackside and on-board, and carried across all three skies.

Voice Application Subsystem

Mission-critical voice, reinvented on MCX.

GSM-R's voice heritage, rebuilt on 3GPP mission-critical push-to-talk — group calls, priority, pre-emption and location-driven call routing.

Railway Emergency Communication

One press floods every cab, dispatcher and handheld in the emergency area — location-scoped, pre-emptive, sub-second call setup.

FRS §10.11 · FIS §4.3

Driver & controller voice

Point-to-point and group voice between drivers, signallers and control — functional addressing by train number, not phone number.

FRS §10.2 · TS 24.379

Shunting communication

Link-assured group voice for shunting teams — handhelds and shunting-loco cabs, with continuous link supervision.

FRS §10.8 · FIS §4.4

Safety-device voice

Driver Safety Device events auto-raise an SOS voice path to dispatch — the pedal is pressed, the network is already talking.

FRS §5.1, §11.34
Critical tier

Train control and the keys that protect it.

The applications where FRMCS earns its "future railway" name: ETCS/ATP and ATO signalling over IP, guarded by railway-grade key management and PKI.

ATP / ETCS

Automatic Train Protection traffic between EVC and RBC over FRMCS — the migration path off GSM-R circuit data, per ERA Subset-037/-098.

FRS §11.4 · Subset-037

ATO

Automatic Train Operation up to GoA4: journey profiles down, status up — energy-optimal driving computed corridor-wide.

FRS §11.5 · Subset-037-3

KMS

Key management for mission-critical services — identity-based crypto (ECCSI/SAKKE), key requests and rotation per TS 33.180.

SRS §15 · TS 33.180

PKI

A railway certificate authority with HSM backing — enrolment and lifecycle for every train, RBC, drone cell and trackside gateway.

SRS §15.4–15.6
Performance tier

The data that runs the operation.

TCMS

Train Control & Management System telemetry off the train bus (TRDP/MVB) to depot diagnostics — predictive maintenance fuel for the AI layer.

FIS §4.5 · Subset-147

Passenger Information

Announcements and displays synchronised across train and station from one workstation — delays explained before passengers ask.

FRS §11.33

Trackside maintenance warning

Geofenced approach warnings to trackworker handhelds and lookout devices — the train announces itself to the people on the line.

FRS §11.7

Critical advisory messaging

Safety-critical advisories to DMI and dispatcher — acknowledged, prioritised, audited.

FRS §11.15

Driver Advisory (C-DAS)

Connected driver advisory: energy-optimal speed profiles streamed to the cab, fed by the corridor digital twin.

FRS §11.25

CCTV — live & archive

H.264/H.265 over RTP from cab, saloon and trackside cameras — live to control on demand, archives offloaded via drone cell or satellite.

FRS §12 · RFC 6184/7798
Perception tier

Anti-collision: the railway that sees ahead.

A train at speed needs 1–3 km to stop — further than any sensor sees, and around curves no sensor can. So FRMCS.ai layers perception across the whole corridor and lets the network share what every eye sees, in seconds.

On-board: the cab radio's eyes

The Jetson Orin cab radio carries a multi-modal forward head — high-speed, day/night and thermal cameras with lidar and radar, fused on the GPU. Obstacles, crossing intrusions and rockfall detected at source; the enabler for driverless GoA3/4.

Drone lookahead

When Elastic Sky is airborne — over an incident or a corridor without towers yet — its perception pod scans kilometres ahead of approaching trains, around curves and over crests. One tether, two missions: coverage + eyes.

Aerial perception · Elastic Sky

Wayside guardians

Fixed camera/lidar at level crossings, platform edges, tunnel portals and landslide zones — inference at the edge, detections reported through the IoT plane.

oneM2M · edge inference

Cooperative sharing

Detections travel train-to-train and train-to-trackside over FRMCS, V2X-style, and land in the corridor twin — a hazard seen by one train warns every train behind it.

FRS §11.15 · §11.7 advisories

Perception informs; certified logic decides. Detections flow as critical advisories to drivers, dispatchers and ATO at network speed — while any brake-triggering path remains a separately certified SIL safety function (EN 5012x). Models improve continuously without reopening the vital safety case.

Beyond the catalogue

The IoT plane underneath.

A oneM2M IoT layer federates wayside sensing into the same platform: axle counters, hot-box detectors, point machines, level-crossing monitors and lone-worker devices report through station-level CSEs to the control centre — and every reading sharpens the AI's picture of the railway.

Symmetric by spec. Ready by design.
