Speed against the effective limit
Section limit, or the caution limit where a restriction applies — with your own tolerance band. Anything over is marked, timed and located to the metre.

Speed Compliance Analytics Engine
Every locomotive run, read end to end — against its caution order, its section limits, the signals it passed and the curve it should have braked on.
This is a real run. Every mark on it is evidence you can point at. Tap a number to see what it means.
Five questions, answered the same way for every train, every time.
Section limit, or the caution limit where a restriction applies — with your own tolerance band. Anything over is marked, timed and located to the metre.
A single yellow means the starter ahead is at danger. Each passage is listed with the aspect, the time it was given, and the speed it was passed at.
The approach is plotted against the standard braking curve, read as distance still to run — and against where the train actually came to stand.
Brake feel and brake power tests are detected from the speed trace at each take-charge and graded against the rule.
Not every restriction binds every train. Line, direction and active window are resolved so a run is judged only by the orders in force for it.
Crew is split by hand-to-hand leg, so a finding attaches to the loco pilot who was actually driving that stretch.
Four lamps at the top of every run: speed, cautions, brake tests, signals. Green or amber, with the count that earned it. The detail is always one scroll away — but you never have to dig for the finding.
Read from station track events and matched to the run by direction — the aspect the signal showed, when it was given, when it was passed, and how fast.
The actual approach against the standard curve, plotted as distance still to run — and a line per station showing where it came to stand.
Pin a point and read it: speed, the limit it was held to, the caution in force, and the signal aspect at that moment — shown as the lamps themselves.
Findings are only useful if they survive the walk to a counselling room. Every run prints as a proper A4 document — run report, exceptions, a 1 mm : 100 m strip appendix, and a counselling slip for the loco pilot.
The dashboard is one of four surfaces. They share the same data and the same language.
