For anyone who wants to know what's actually going on here, under normal conditions, the gate mechanisms are always receiving power, there is a mechanism (called the whole-clear mechanism) that latches the gate up, and it needs the power to do so. when a train is coming, the controller cuts power to the gates, causing that whole clear mechanism to release, dropping the gates. when the train is passed, power is then applied, and because the gate is down (because it holds a switch when it's up), power is applied to the motor and the gate rises again. when the gate reaches its full up-ness, it holds that switch which sends power to the whole clear mechanism that holds the gate up and cuts power to the motor. whats going on here? the whole clear mechanism has failed, causing the gate to drop, but as soon as it starts going down it releases the previously mentioned switch, which applies power to the motor, which brings the gate up again, which presses that switch which cuts power to the motor, but the whole clear mechanism isn't working, so it drops again, releasing the switch, causing power to be sent to the motor, which brings it back up and holds that switch, which cuts power to it and the gate begins to drop, which releases the switch which powers the motor which brings it back up, and so on, and so on, and so on. hope someone found this interesting or helpful.
What happened here is a hold-clear mechanism failure. The hold-clear mechanism under normal conditions keeps the gate up. When the signal bungalow says to lower the gates when a train is coming or a power cut long enough to drain the backup batteries occurs, it moves to allow the gate to lower. When this mechanism is not properly working, the gate can drop but hits the hold-clear mechanism, causing it to go back up, and down, and repeating until a railroad worker arrives to fix it.
Thank you! Glad you like it! My friends and I were going to see about another train and I said “crossing activation!” And we pulled up to it not realizing this as going on for 10 minutes.
So I've seen this before, when the gate is up there's a mechanism inside that locks the gear in place to hold the gate up. When the mechanism isn't locked, the gate tries to fall but it's supposed to be up, so then the lift function is activated. So this shaking is caused by the gate being released and being pulled up into the up position and it is repeating.
And the lights/bells are designed to be activated if any gate is not raised properly. So they keep cycling because the gate with the failed hold-clear mechanism keeps crossing that boundary. The pumping can quickly destroy the gate mechanism. Fancy gate mech models have electronics that detect this situation and cut the power temporarily.
Crossing: *sees the trains's ditch lights* Also crossing: *having a severe seizure* edit: 2 years later and i'm now realising this crossing sounds like one of those crossings from the czech republic.
Bad “park pawl” adjustment on the gate motor, it keeps fighting itself to lock the gate in the up position. If the person recording would have pushed the counterweight on the bottom to hold it they would have shut off
You're so right!😄 Somewhere near the beginning of the movie when Richard Dreyfuss is driving in his car and everything starts malfunctioning all around him. That was freaky and so was this.
Looks like a mechanism failure. It can not keep the gate up, but yet tries to pull it up when it goes down. Causing it to shake, and the other signals to activate with it since they all activate together.
the signals locks were put in wrong so the signals think theres a train coming but the relay case is saying theres no train so the relay case and the lock are fighting over the crossing
There's no lock. But there is an electromagnet designed to hold the gate up when the signal is off. If power were to be lost, the magnet will turn off and gravity will drop the gate to horizontal to protect the crossing. (This is an example of safe failure.) There is something wrong with that electromagnet, which is causing the gate to drop far enough to activate the lights and the motor to drive it back up.
Wow!!! That really is a different kind of malfunction!!! I ain’t ever seen a level crossing behave like that. I suspect the power wire is loose, crossing paths into a pulsating standby circuit.
Nah, not a loose power wire. Ironically, the signal should work just fine if a train actually comes. It's only when the signal is supposed to be OFF that it has a problem. I wrote a more-detailed explanation in a response to *@james toyn* if you're interested.
I hope Florida East Coast check the securement bolts down in the concrete base because that's severe pumping there's no telling if that thing got loose suddenly out of nowhere the whole crossing signal just topples into the street.
Out of curiosity how did they even activate in the first place? And who shut them off? Did they take forever to shut them off? Sorry for all the questions I’ve just never seen this happen lol. I showed my mom and she worked for the FCC (I hope I’m correct) and she said “I have seen railroad crossings do many things but this is a first for this. I’ve seen the gates go down and the lights not light up and the lights light up and gates stay up and trains derail and collide and the lights fall off. But not this.”
Only the top bolt holding the light unit in the housing vibrated its way out. The light is hinged at the bottom and designed to flip out for maintenance or inspection. The whole light won't fall off the hinge.
Boom gates like this require power to remain in the Up position. Not a lot of power, but just enough. This is a failsafe design, which allows the gate to drop by gravity, should all utility and backup power to the crossing be lost. A lowered gate will be a warning not to use the crossing (it's illegal to do so) even if no train is coming, which I'm sure you'll agree is much safer than a train coming and the signals looking normal and off and failing to work entirely. There is an electromagnet in the gate mechanism case which is responsible for holding the gate up. It's called the "Hold Clear" mechanism. Here, that device is not calibrated correctly, or is damaged or failing. So, it can't do its job and the gate starts to drop. But there is still power, so after the gate drops enough, the contacts engage to activate the motor to drive the gate back up, just as if a train had just passed and it's time to raise the gate. Once the gate gets back up, the motor shuts off... and then the cycle begins again. This is happening over and and over. Note that this malfunction does not interfere with the normal operation of the signal or gate. When a train comes, the gate and signal should operate as expected. Once the train passes and the gates go back up, the malfunction will become evident again. The mechanical shock and wear on the motor is not good, though, and if not corrected the gate mechanism will eventually destroy itself. So, if you ever see this type of malfunction, call it in.
They are gonna have to tighten the base bolts on the signal after a malfunction like that because the pumping gate shaking the signal does damage to the base
We had that happen at a crossing here one time. It was very similar to this set up but was a quad gate crossing over a four lane road. Never did understand why it kept doing that very same thing. Maybe someone here can explain that to me.
Grade crossing signals are designed to fail safely. A small amount of current is constantly required to keep the gates in the up position. So, should the power fail completely, the gates will drop by gravity to the danger position. For the one signal, the mechanism that uses that small amount of current to keep the gate up is not working properly, so the gate starts to drop. But there's no power failure, so once the gate drops so far, the contacts in the gate mechanism turn the motor on to drive the gate back up (as if a train had just passed). The gate goes back up, the motor turns off, but then the cycle repeats. The bells/lights come on because they're wired to activate if any of the gates are not properly vertical.
ive seen videos of something similar where a gate was spasming i would assume due do a short circuit and i can only imagine thats whats causing this gate to spasm.
Nah, not a short. A tiny bit of power to a magnet holds the gate up, and that system is not working for one of the gates. I wrote a more-detailed explanation in a response to *@james toyn* if you're interested.
All railroad signaling equipment is designed to _fail safely_. Crossing signals fail and activate with no train because that's the safer course. Imagine how horrible it would be if they usually failled and then never activated when a train came! (Which does rarely happen, usually through human error.)
And to answer your question: If it's new as you say, it's likely the gate mechanism was not installed correctly. Some of the mechanicals in them have pretty rigid tolerances and if they're out of spec, this is the type of thing that can happen. The crossing gates should still work correctly when a train comes, however.
Not common, but not un-heard of. Unfortunately, this type of malfunction slowly destroys the gate mechanism. Some gate mechanism have electronics inside to detect this problem, and to cut the power to prevent damage.

the whole clear mechanism has failed, causing the gate to drop, but as soon as it starts going down it releases the previously mentioned switch, which applies power to the motor, which brings the gate up again, which presses that switch which cuts power to the motor, but the whole clear mechanism isn't working, so it drops again, releasing the switch, causing power to be sent to the motor, which brings it back up and holds that switch, which cuts power to it and the gate begins to drop, which releases the switch which powers the motor which brings it back up, and so on, and so on, and so on.

It isn’t the controller’s fault because it is that one signal doing it.
The gate mechanism is failing to keep the gate up.
@@DanTDMJace that’s what I said but in much more detail.
does that mean that during a power outage, the gates will automatically go down due to lack of power?
@@asasnat342 yes, but there is batteries in the relay cases so the signals will still function for a while before the gates drop.
Did they even fix the crossing light that fell out?

One of those signals wasn't tightened properly, causing one of the lights to fall off.
Can I use a bit of your clip for a Top 5 video?
that one gate motor is getting a workout lol
Music to my ears.
The hold clear mechanism is malfunctioning so the switch attempts to open the gate all the way. That is why the motor keeps going and stopping.
Crossing had a stroke and a seizure and then it injured itself with it’s lights.
LOLLLLLLLLLL
😌
Now that I rewatch the malfunction it looks like the crossing is trying to dance, but with a light injury.

I think is that the gate is bouncing and if it goes down a certain amount the lights and bells go
the signals locks were put in wrong so the signals think theres a train coming but the relay case is saying theres no train so the relay case and the lock are fighting over the crossing
No. Hold Clear Mechanism failure.
This won't be the only crossing to do this.. I've got one by me that the crossing gate sticks way out from the gate holder.
Nah! They're not malfunctioning. They're just doin' the Tuesday night railroad crossing groove! 🕺🥳💃
Which crossing light fell off at 1:46? I don’t see one.
I guess the lock on the gate is not working, so it keeps falling and the motor has to move it back up.
