Recorded message on 450.050

Post by freqwaves » Tue Aug 27, 2013 9:17 pm

I am hearing in Campbelltown on Railcorps 450.050 a recorded message every 10mins or so.I heard this on the weekend as well.
It says something like this "tango sector 67.2kms with no defects,I repeat no defects"

No subtone captured.Still getting the general broadcasts from Campbelltown box on this frequency with subtone 173.8.
Anyone else captured this?

Thanks, John.

Hi all,
Ive heard a similar recorded message up in the Southern Highlands. I got told it lets drivers know if theres been a landslip at a certain spot. Given Menangle rail station is 1.9km north of the spot mentioned(65.330km) there could have been trackwork there or a problem of some sort?
Cheers

Guys,

These are Hot Box (axle bearings) Detectors or Dragging Equipment (tarps) Detectors or Axle Counters. The one you are hearing John is at Menagle and is a HBD. As a train passes, it uses laser driven thermometers to check each axle as it passes a certain point in the track. It then broadcasts to the crew that the train has no defects or that axle ### is a problem. Most of these detectors are landlined back to Enfield SIgnal Box who then rings the appropriate control certain who then notify the train in question. There are some that TX on WB.
