A camera in my study watches line 011 from sunrise to sunset. It counts every train, finds it in the timetable and notices when it honks.
Since 27 September 2026 we watched for 443 hours and saw 14,151 trains: one every 1.9 min on average. 314 of them honked, 384 times in all.

Punctuality
The camera sees when a train actually passes and compares it with the timetable. Shown for the trains whose position PID reports; on time means less than 5 minutes late.

Biggest delay+111 minR 886 Slovácký expres · 3 Oct 18:50
Long-distance trains (EC, RJ, LE, railjet…) show no delay here: we find them with help from Správa železnic's data, which we don't publish yet. That's 3,157 runs.
534 runs were placed by the timetable alone, so they aren't counted for punctuality.
