Rail & Transit
Configurable auxiliary power control and circuit data for rolling stock and transit vehicles.
The challenge
Every delay starts to add up.
Rail vehicles and transit systems rely on complex electrical systems that have to work every time.
Service disruptions
Electrical faults can take trains out of service and disrupt timetables.
Complex and ageing wiring
Long service lives mean years of modifications that make faults hard to trace.
Poor visibility
Intermittent auxiliary faults can be hard to reconstruct without circuit-level records.
How Hardwire helps
Configurable auxiliary power control for rolling stock.
Solid-state switching
Solid-state outputs replace mechanical relay switching on suitable auxiliary circuits.
Configurable protection
Per-circuit protection set to suit each cable and load, within an approved design.
Circuit data
Current and fault records for monitored circuits; remote access not included.
Diagnostic logs
Logged output data to help narrow depot investigations.
Typical applications
Where it’s used on the train.
Candidate non-critical 12/24 V circuits only, each classified for the target train and approved by the operator before a pilot. Door interlocks and emergency lighting are excluded.
Selected saloon lighting
Non-emergency saloon lighting circuits.
Passenger information
Display and announcement system supplies.
CCTV supplies
Camera and recorder power.
Telematics
Fleet tracking and condition monitoring units.
Wi-Fi & comms
Passenger Wi-Fi and modem supplies.
Other non-critical 12/24 V
Classified circuit by circuit, with operator approval.
