9 On the Train Summary report, check the Axles column.
Axle count should be an even number. Odd-numbered axle counts are possible
indications of gating transducer problems.
If there is an odd axle count and if train
speed was always above 7 mph (11.3 kph), go to step 16 .
If at any time during train passage the train speed was less than or equal to 7 mph
(11.3 kph), gating transducer problems probably don't exist. If the train speed was
always above 7 mph (11.3 kph), gating transducer problems probably do exist.
The Very Slow Train alarm indicates that, at some point during train passage, four
consecutive axles crossed the gating transducers at a speed of 7 mph (11.3 kph) or
less. This alarm appears on a Train Detail report.
If there are many very slow trains (that is, many trains traveling less than 7 mph
(11.3 kph) at this site, it may be necessary to relocate the scanners and other track
hardware to a better location. Deciding to do this should be made in consultation with
STC. Relocating a site is beyond the scope of this document.
10 If there is an even axle count and the values under "Axles," "TO1," and "TO2" are the
same, go to step
24 .
If things are working correctly, all three values for a given train should be equal. Do the
next step only if things aren't working correctly.
11 At trackside, check all transducer-mounting bolts on all tracks to make sure that all
transducers are snug against the rail.
Four bolts are needed to hold the transducer in place. Two square-head bolts go
through the mounting plate and transducer body. Two hex-head bolts go through the
mounting plate and rail. If any of these bolts are sheared or missing, replace them.
Also, if any washers or nuts are missing, they must be replaced.
12 If all transducers aren't snug against the rail, fix this problem before proceeding.
Each installed transducer body should be 1-9/16 inches (3.97 centimeters) below the
top of the rail and parallel to it. You can meet this requirement by using the transducer
height bracket on the bottom of the alignment fixture.
13 Place the alignment fixture across both rails, centered over each transducer in turn.
