I really appreciate you specifically saying "safely get into a position" and using a zoom to detail the system at 1:46 such that you do not foul the right-of-way. That's class and a great example for the public.
4:12 That big cooled equipment box or building may look big, but you have to remember that the section foreman and a railroad agent live in there. My dad grew up in one of those when he was a kid back in the 'thirties.
Watching in the year 2020, inspite of the age of this video, I find the information on these to be relevant and informative for people who want to know or who are curious about the stuff on a railroad or rail line.
I believe some defect detectors also register on the PTC board with the dispatcher. I also noted locally, that the defect detector radio transmitter is very low power, only audible for about a mile. I live 2.5 airline miles from the detector but can't hear it at home, yet I can hear the locomotive radio transmitters from almost 15 miles away. Thanks for the details.
At first, it looked almost like the detector, one on the P&W's Gardner, MA branches, being installed afer a string of Auto Racks derailed. (The wheels were already off of the track as P&W pulled them out of the B&M Gardner interchange, as evident by the pavement groove marks in the nearby grade crossing.) I am unsure if they might use it just so to count the number of axles of the train they are picking up from Guilford's B&M. There is also a Dragging Equipment Detector in the mix.
i learned alot from this ty. i do rail work on virtual railroads such as ones in secondlife so this helped me out alot on bringing defect detectors to virtual railroads :)
I don't have to rely on making videos to survive or for extra cash, so I don't. Views should be counted by watching a video from beginning to end. That way, click bait, which most of them are, wouldn't clog up UA-cam with the trash and mislabeled titles like JT. If it can't be explained with 5 minutes it is filled with worthless content for any more than that. hnf1930 did it in 4:28. See what I mean ?
My residence is Abram mp 20 (20 miles east of Greensboro's Pomona yard. There's a sensor at mp 15.5, so I use it to determine when an eastbound Norfolk Southern or Amtrak will be passing my location pretty soon
Is there a way to trip a dectector by hand. Like if you wave your hand a couple of times past a sensor will it think its a train and give a callout on the scanner or something?
Good vid, thanks. I wish to second the request for a vid about signaling crossings for gates, lights, bells & whatever else they have. How do they work?
t. hof the approach/ departure blocks are insulated from tbe rest of the rails. A low voltage is transmitted( 12-20v.). When train,enters block, it shorts out the voltage, cutti ng power to armature, allowing gates to drop & activate lights/bells. when last trucks clear the block, voltage resumes, armature loses power, allowing gate
np man, great job, i like looking at trains and what knot, but didn't know about all of the other stuff "behind the scenes" that goes on to make it happen
Thanks for the primer. I would like to see systems that registers defect in the railway track and bed itself. What are the levels of inspections(Preliminary to Advanced)and how often are the different inspections performed? Continuity tests, Ultrasonic tests, Radio cars, Dr Yellow (Japanese track inspection train), Track inspection trucks and their equipment. Just throwing some ideas onto your tool box. I will have to subscribe to your channel because I suspect you already have answers to a lot of this already.
Thank you so much for watching, and your support. I encourage you to continue watching Jaw Tooth. His videos are very entertaining....Roll that video son!! LOL
the framing that looks like a signal bridge is for holding light emitters and receivers to determine if loads have shifted out of the clearance limits or/and are too high for an overhead clearance. Places where these are common are a safe distance before through truss bridges and tunnels. I have seen and photographed what a shifted load does to a through truss bridge. The signal equipment box looks like a standard box like at a grade crossing.
WHEN U BUILD A TRACK, HOW DO YOU KNOW HOW MUCH BEND TO PUT IN IT? HOW MUCH BEND CAN THE TRUCKS DO BEFORE THEY COME OFF THE RAIL. DO THIS DEPEND ON HOW LONG THE TRUCK IS? I OFTEN HAVE DERAIL PROBLEMS WITH MY 3 AND 4 AXLE TRUCKS [ ON ENGINES ], YES I NOW THE DIFFERENCE TWEEN REAL AND HO GAUGE.. THEY COMPINSATE WITH AXLE SLOP BUT HOW DO REAL TRAINS COPE WITH TIGHT TURNS. IS THERE A RATIO OR MATHMATICAL FORMULA FOR TURNS?
Jackson Slater ElevatorRailAlarmFan Detector will not transmit just by pushing over deflectors. It first needs to be switched from standby to ready by an approach signal set by first 4 axles of train.
Great video. Thanks! I put together a slideshow video on defect detection. If you can check it out and comment for content/errors that would help as I am learning all this and applying some of it on my O-Gauge model trains.
Lol what if it announced Integrity Failure I would be laughing at it again, I have only seen these do it once, I might go next to one today and see how it will work for TRE if it does
Yes this is a Southern Technologies "Sentry" Detector, you can tell this by the type of pyros and transducers being used. These are being phased out and replaced with newer Southern Technologies detectors.
Thank you, Todd. My territory uses the Progress Rail Mini-Talkers that are rated for our high speeds (125mph to 135mph) & set to talk on alarms only, since, they are connected via modems to our command center. I've worked with the Servo 7707 (ballast mounted scanners & vacuum tubes), 7708 (a hybrid of the older 7707 outfitted with the Servo 8808 rail mounted scanners), Servo 8808, and the CyberScan 2000 (Harmon product after they had bought the Servo Corp) which have now been replaced with the Progress Rail systems. The Servo 7707's originally had only 2 transducers. Later, advance start transducers were added about 75 feet north & south of the scanners, because, as the train speeds were increasing the 1st wheels would be missed. Adding the advance start transducers had eliminated this problem.

There are also Hot Wheel and Loose Wheel detectors as well as High/Wide detectors.
Don't forget high water detection at bridges crossing arroyos, creeks and rivers.
That detector building is bigger than my apartment.
The asymmetric weight detector is something I didn't know about.
Thanks for this very informative video
I enjoyed this little summary. Thank you Jawtooth.
Thank you but this wasn't my video. Lol
Yes, because if it was JT's video it would be 1:19 of relevant information and the rest worthless bullshit.

Thanks for the info. Makes railroad fanning more fun.
That's a great safety system. I'm sure it has helped avoid many accidents. Thanks.
Thank you for taking the time to make this video. It was super helpful in understanding how defect detectors work.
Oh hey that’s the older Norfolk Southern detectors. Southern Technologies Corp Sentry System.
Yes, the video is several years old
Thanks for a neat educational video!
i learned alot from this ty. i do rail work on virtual railroads such as ones in secondlife so this helped me out alot on bringing defect detectors to virtual railroads :)
Christopher Strachan Great!
Thanks for watching
How did you get Dale Earnhardt Jr to narrate your video?
Haha, I thought same thing as well!
😆
I came here to say that sounds like Dale Jr, but you all beat me to it :)
I’m dead
Sounds nothing like Dale Jr. imo.
Very nice video and very informative!
Yes, because if it was your video it would be 1:19 of relevant information and the rest worthless bullshit.
San Francisco he still makes better videos than you.

Interesting learning something new. Didn’t know that was how the dragging part worked.
Thank you sir. That was a very informative video on train safety.
That is a very great description and I love it. Great information. Thank you.
Is there a way to trip a dectector by hand. Like if you wave your hand a couple of times past a sensor will it think its a train and give a callout on the scanner or something?
Very informative...thanks for sharing...there is one of these detectors at one of my railfanning spots and I have been wondering what it is.
Thank you so much for watching
Good vid, thanks.
I wish to second the request for a vid about signaling crossings for gates, lights, bells & whatever else they have. How do they work?
Nice coverage.
Very good information. I would like to learn how R/R crossing signals operate.
t. hof the approach/ departure blocks are insulated from tbe rest of the rails. A low voltage is transmitted( 12-20v.). When train,enters block, it shorts out the voltage, cutti
ng power to armature, allowing
gates to drop & activate
lights/bells. when last trucks clear the block, voltage resumes, armature loses power, allowing gate
Allowing armature to raise gates, turning off lights.
Nice info. thanks!
Thank you for watching!
can you do a video on how the activation part that controls the crossing arms and what knot work?
great in depth videos man
I will finish the crossing gate video and post it in a day or so. Thanks for watching
np man, great job, i like looking at trains and what knot, but didn't know about all of the other stuff "behind the scenes" that goes on to make it happen

Great vid. I've seen those before and have wondered what they do. Now I know -- thanks to your video.
Thank you. That was very informative
*Norfolk Southern detectors must stay quite busy... They're always hitting and running over stuff*
Was said that the Seaboard Coastline( now CSX) pioneered the defect detector...
The rail road spicks are loose and missing right around the detector
where can i get one? i see people use them all the time
EXCELLENT VIDEO,VERY GOOD INFORMATION.
Awesome info ... Thanks for great video
Thank you so much for watching
Thanks for doing this video, now I know how those detectors work! It's neat technology.
And your video is better than the one Jaw Tooth did lol.
Thank you so much for watching, and your support. I encourage you to continue watching Jaw Tooth. His videos are very entertaining....Roll that video son!! LOL
Thanks for the information.😁
Cool! Thanks for posting the awesome video! Learn something new every day! :)
What's the spacing for the "A" & "B" transducers shown in this video? Looks wider than the 24 inch spacing we use.
Great video, very interesting
+RailTube Thank you so much
oh.. i thought this was the Railroad Crossing sensor , wrong video but interesting.
Sounds like Dale Earnhardt Jr lmao
Why is that funny?
@@hnf1930 I think it's cool!
thank you. i have been waiting for a video on that subject.
Great video. I learned a lot.
thanks for sharing
The one near our house is like a signal bridge!
Ultimate Railfan I would like to see that.....it sounds cool

The defect detectors doesn't have a mechanical voices. They are voiced by real actors, and actresses like Union Pacific for example.
How far apart are these detectors placed or does that vary.
It does vary, based on track speed for most. Thank you for watching.
Great coverage. Thanks!
Good explination.
Thank you and thank you for watching!
had u pushed the part on the track forward it would've tripped the detector
Jackson Slater ElevatorRailAlarmFan
Detector will not transmit just by pushing over deflectors. It first needs to be switched from standby to ready by an approach signal set by first 4 axles of train.
very good!
Curious. Didn't the EOTs used to transmit on 161.115? :) Tnx
Or Amtrak

I have heard this detector go off with "dragging equipment" before
Thanks for watching!
Is this a Southern Technology brand system? Thank you - nice video, too.

👍🏻👍🏻👍🏻👍🏻
norfolk and southern wrong its just norfolk southern
Used to be Norfolk & Western. Pretty soon it will be Norfolk 'n WayPal.....
I hate hobos
LOL
