Rail trackside equipment
Trackside equipment far from depots, serviced in short windows.

“Capability is a depleting resource to be spent, not a fixed budget to be defended.”
Whitepaper, §5
Remote lines depend on trackside condition monitoring: hot-box detectors, weather stations, slope sensors. Many sit far from depots, and each failure is a trip.
Mru Field runs on the processors already in the equipment. When one fails and nobody can come, it continues on the ones left and delivers only results it can check. Status: decision core at TRL 3; first field pilot planned for 2027.
01
Computers fail one by one
Radiation, heat and age take out processors and memory. Nothing is replaced until the next visit.
02
No one to ask
When two computers disagree, there is no operator to say which one is right.
03
Power runs down
Batteries fade and panels foul. The system has to do less, on purpose, and keep the important part going.
Three computers. Then two. Then one, still working.
Most redundant systems stop when they lose their majority. Mru Field steps down instead, and says which mode it is in.
3 alive · vote
Three computers vote. One bad result is outvoted.
2 alive · compare
Two compare. A known-answer test finds the faulty one.
1 alive · self-check
The last one checks its own work and keeps watching the line, at half speed.

Questions
Does Mru Field need new hardware?
No. It is software for the processors you already deploy. It runs beside your control code and decides which computer to trust as parts fail.
Is this for signalling?
No. Signalling keeps its own certified safety systems. Mru Field is for condition monitoring.
How do we start?
Use the form below. We first model your hardware and show what each redundancy design returns over its whole life. Then we plan a pilot on your own equipment.
