A question about what detectors say

[redrooster]

Hi,
I am in the process of writing a computer program for a class, that based on the users inputs, would produce a text printout that simulates what a typical Union Pacific Hotbox/Dragging Equipment would say as the train goes over it. I do realize from listening online, that not all detectors even on the same railroad, always say the same thing. I am modeling my program on the Geneva Subdivision area detectors. My question relates to what the detector would say for a Train Too Slow case and an Integrity Failure.

Currently I have the program set to produce these printouts and I was wondering if they were correct?

Integrity Failure:

UP DETECTOR
MILEPOST 98.2
TRACK 1
INTEGRITY FAILURE
UP DETECTOR
MILEPOST 98.2
TRACK 1
INTEGRITY FAILURE
DETECTOR OUT

Train Too Slow:

UP DETECTOR
MILEPOST 98.2
TRACK 1
TRAIN TOO SLOW
TOTAL AXLES 368
TEMPERATURE 57 DEGREES
DETECTOR OUT

My question for both cases is; are the total axles, temperature, and train speed displayed in the correct manner?

Thank you for your help.

I don't think it can detect the axle count if the train is too slow. I think that's what happens on the detectors around here.

Thank you for the information Bill. I updated it so it does not display the axle count or the temperature. I think at this point my main question is if it is a train too slow case, does it repeat the broadcast like the BNSF detectors do?

I currently have it set to do this:

UP DETECTOR
MILEPOST 98.2
TRACK 1
TRAIN TOO SLOW
DETECTOR OUT

but I'm wondering if this is more accurate:


UP DETECTOR
MILEPOST 98.2
TRACK 1
TRAIN TOO SLOW
UP DETECTOR
MILEPOST 98.2
TRACK 1
TRAIN TOO SLOW
DETECTOR OUT

It seems like in the case of integrity failure and train too slow the norm is for the broadcast to be repeated, but I'm not sure if this is true for the UP train too slow broadcasts.

My main experience is with BNSF detectors and from what I recall, they do not repeat,even in a Too Slow condition. Trouble is, you just don't hear that message very often.
