Hot Box Detectors - ROBOTIC Voices on the Railroad

[@tomy6917]

At the 1:32 time mark, the "axle counters" are known as the "Gating Transducers" which are magnets encased in fiberglass. When the wheel flange passes over them it generates an AC voltage of about 1/2 volt. In addition to counting the axles, they also tell the system to start taking infra-red samples of the wheel bearing & then the next one stops the sample collection & this gets repeated for each flange. The HBD scanners use infra-red sensitive photo-resistors to "look" at the bearings & uses the underside of the car's body as an outdoor ambient temperature reference. The infra-red sensors don't actually send out a beam, but, instead changes its resistance value based on how much infra-red heat was seen from the bearing. Two alarm criterias are set, Absolute where if any bearing reads a certain temperature that will equal an alarm (we used 205 degrees F on Amtrak's NEC) and there's the "Differential" alarm that alarms based on how many degrees one bearing reads compared to the bearing on the opposite side (we used 104 degrees difference). Alarm criteria varies by each railroad for what temperature levels are to be "alarms".

That is really interesting. I appreciate the detailed explanation. Thanks for sharing!

[@QRPadventures]

Interesting... thanks!

[@aerialtrains6625]

It's so interesting to hear defect detectors in the wild. However, I have learned they are not all the same. On some CSX they will even tell you the axel count, speed, and total length of the train! On NS, they only say if there is a defect or not, and doesn't give you any more information, but the same defect detector will chip the same message twice just seconds apart from each other.

Yes they are programmable to whatever the railroad wants, defect detectors can report Speed Ambient temp Total cars Total axles Total length Direction (east west north south) Track number

[@WestCoastRailroadProductions]

anybody here know how to make defect detectors in roblox?

Thanks for Sharing the info about how the Railroad keeps an eye on their moving train cars. 👍

Thanks for watching!

This was very informative and well-produced. Thank you.

Thanks!

[@KDubielak]

I have the same exact radio just as you I sometimes use it for railfanning and chasing trains

[@BrickSaturn]

I don't think I can double like a video, so here's my second thumbs up. 👍 Thank you for all your work here on KZbin.

Thank you for watching!

Thanks for this cool and descriptive video! I'm still attempting a set up a recording system from my location to try and receive the SG 552.4 DD once more. It worked a while back in December up till January 12th with the TrainTenna from DPD Productions but lately it hasn't been coming in anymore.

[@v12productions]

Thanks for watching! Best of luck with your recording.

[@josephjones6539]

Thanks much! Always enjoy your videos and catches 😊

[@stargazer7644]

Temperature detectors don't shoot an infrared beam, they look at the bearing that is radiating in thermal infrared. Hot objects emit infrared. If they get hot enough, they'll emit visible red or yellow light.

Nice video as always man! This train was Q583 but man I wish you could've heard that lead units horn...it has a very nice sounding RS3K. Had a hobo on one of the reffer cars.

[@v12productions]

Thanks! Wish I could have heard it too. Quiet zones... ) :

If you ever want to do a vid on track greasers and their equipment, come out to the Stone Mountain Railroad. There's a number of them in public access and you can get right up on them to examine the hardware.

[@v12productions]

That's definitely on my list. I was going to look at the one near downtown Decatur, but I didn't know Stone Mountain had them.

[@the101stdalmatian8]

@@v12productions there's three on the SMRR. One is right at the walk up trail to the right side of the main platform between the platform and the access road. Very easy to get to and the trails are right up alongside it.

[@NERRP2017]

Ironically the defect detectors in my area along the CSX Berkshire/Boston subdivision used to say Conrail Defect Detector back In the early 2000’s, sadly as of now they no longer say Conrail and the software was replaced to say CSX

This voice doesn’t sound robotic at all. This voice in particular is my favorite.

Awesome, thanks!

I played the defect detector sound at lowest speed and it got me dying laughing

I don't understand why the hot box detectors near East Palestine, Ohio didn't alert the crew of the hot box until it was too late

We have those on BNSF Too But I love the part saids repeat

You should’ve gotten the first train at a spot further up the line. That lead engine has an RS3K horn.

I think the axle count malfunction may be that the number is an odd number, is it possible for a train to have an odd number of axles

[@curailproductions7636]

Nice 👍

269ner? What’s a NINER! This voice ain’t a man. It’s an old timer. More like some defects. Some defects: who the hell hired me

[@SignalAspect]

Basically they say niner because on the radio, it has crackling because of the frequency. 5 and 9 would sound the same, so they make the detector say niner to hear the numbers better.

[@chris52209]

niner is a way to differentiate between 'nine' the number and 'nein' the word for no in german and other words or sounds that sound like the number 9
