When a catastrophic transducer failure occurs in conjunction with an auxiliary alarm, alarm
announcements omit the alarm sequence numbers (that is, “first,” “second,” … “ninth”), the
axle numbers, and the phrase “From Head Of Train.” If announcing a “Multiple … Detected
From Axle… To End of Train” message, “From Axle… To End of Train” does not announce.
For example, at a single
‑
track site with a malfunctioning TO1 transducer, an active Dragging
Equipment output within the first three recorded axles, and a Hotbox alarm, the announcement
is like this.
