RFID in RAIL

Uncompromising safety.

Purpose of Wayside Train Monitoring Systems (WTMS).

Safety

Detect and eliminate potentially

dangerous train conditions before

an incident occurs

Availability

Maintain track availability with early

detection and appropriate intervention

measures

Train monitoring systems.

WTMS overview.

Dragging equipment detection

(Availability)

Preventing damage to the

infrastructure caused by low

hanging objects

Natural hazard alarm

systems (Safety)

Preventing collisions with obstructions

in the event of rockfall, landslide,

mudslide or avalanche

Uplift measurement

(Availability)

Preventing contact line faults

WTMS network

(Safety, availaility, case

processing)

•Centrally recording all alerts and

interventions

•Providing data to RUS for

maintenance optimisation and

protection of infrastructure;

e.g. early warning in the event of

misshapen wheels, defective bogies

or badly adjusted pantographs

before a limit is exceeded.

Profile clearance and aerial

detection (Safety)

•Preventing clearance

profile breaches

•Preventing contact line damage

by vehicle aerials on rolling roads

Hot box and blocked-brake

dectection (Safety)

Preventing derailment due to

bearing and break defects

Wheel load checkpoints

(Safety)

•detecting load displacement,

axel overloading

•severe wheel defects

•route loading (load spectrums)

Fire and chemical detection

(Safety)

•Preventing safety-critical

situations due to fire or loss of

hazardous goods


Radio Frequency

Identification (RFID)

• Unique vehicle identification

• Less repeated alarms

• Simple tracking

Uncompromising safety.

Network setup based on risk analysis.

Infrastructure

• 1 Intervention center

Benefits for rolling stock owners.

• Optimized LCC due to early detection of defects

and minimized corrective measures

• Higher availability, no unexpected train stops and

unscheduled repairs due

• Prozess optimization, permanent condition

monitoring by WTMS

• Higher customer comfort due to overall improved

condition
