    Wait til you hear about railroad crossings that don't even have "gate" technology agony-deep

    The backup method is "train lays on its horn the entire time it crosses through the city and hops for the best" which makes it super miserable to live within a mile of those tracks bc they need to do that no matter what time of day or night it is

      They do it regardless of whether or not it has a crossing. I used to live right next to a proper crossing and they still blared their horn. While it wasn't fun, it was easy to tune it out after a month or so.

        Growing up next to a set of tracks, I purposely go out if my way to find places to live near them. I find it very comforting. The fact that places like that tend to be cheaper is just a bonus.

          Yeah I love hearing the train go by at night. At my mom's current place it's like 30 feet from the tracks which was a little much but where I lived in high school it was perfect

        Federal Railroad Administration rules on this are rather excessive in my opinion. To see how these safety rules can backfire look no further than Caltrain's morning rush hour. These are brand-new, quiet and smooth electric trains but because of the rules the bells and whistles are so loud it sounds like some sort of 5-alarm emergency! But no, that's just a normal morning. My heart goes out to any easily overstimulated people near railroad crossings.

      I remember as a kid crossing Australia, we got stuck at a really long train crossing in front of us. It was visibly moving, but not very fast. We wound up having a picnic on the side of the road. It was an event when the end of the train came trailing along like an hour or so later.

      Aren't quad gates the FRA requirement to not have to use your horn at a level crossing?

      I live far enough away from a crossing that I get to just hear the Bwaaaaa in the distance. if the window's closed its hardly noticeable but if i want to hear train noises I just open it up and ill hear the wheels and squeaks and shit.

      It's the simple pleasures

    carbains cannot comprehend that there's a vehicle with even more momentum and even less stopping power than their wankpanzers. Even with an insane amount of warning a freight train wouldn't be able to stop in time, and when they do there's no guarantee they'd get going if they're near an incline or something.

      One of the most hilarious ineptitudes I saw on reddit-logo was when I commented on some story about someone getting hit by a subway train, saying how fast a typical passenger car would have to be going to match the force of an NYC subway train going one mile per hour. I don’t remember the exact number but it was pretty high.

      However, one guy responded that he just didn’t believe it, that there was no way something going only one mile per hour could have that much force. A bunch of people chimed in, tried to explain the F = MA to him, but no, it would not compute in his brain.

        It's not accurate to say something going that slow does or not have that much force. It has momentum. Force is change in momentum, which happens over time. Something moving very slow but is very massive will apply a very small impulse (change in momentum) to a human because the collision with the human is elastic. If the human was strapped to a board and the board was anchored, the train would crush the human, but otherwise the human is going to be pushed out of the way, whereas something going much faster but with significant less mass is going to shatter the human because the elasticity of the human is not sufficient to disperse the force fast enough.

          now if we can find a way to harness a tiny subway car that can travel super fast, we could launch them into the bourgeois class and finally destroy capitalism

    There is, it's called "an engineer" using the technology of "their own fuckin eyes" and "pulling the brake handle." But it still takes a long time for the train to stop, which is why you don't drive around the crossing gates.

    at grade crossings are pretty dangerous. the tech that actually solves this is called "grade separation" but it's unfortunately a lot more expensive so people complain about the cost.

      Part of why Brightline isn't and will never be real HSR is because it still has level crossings.

        they're building brightline west which afaik will be grade separated and true HSR.

    Guilty pleasure when stories like this are on Facebook. Bunch of carbrains acting like it's super difficult to stay behind a barrier or avoid racing a fucking train.

      Most preschool children understand that when the gates close it means that a train is coming and that you shouldn't go in there since the train is going to win a 1v1 against you every single time. How can you be so carbrained that you don't get that you should stay out of the way of a moving train?

    Perhaps this is unkind but a better solution would be to make the train more robust so the foolishness of the motorist does not harm the people on the train

      The FRA tried this for ages and it just made American trains incredibly heavy, expensive, and unique. And of course they still had to come out of service after a collision.

      Now we can mostly use European trains off the shelf, which is much better.

    As Hexbear's resident train nerd, this tech actually does exist to my knowledge. Japan uses it extensively, which makes sense considering their very busy railways with frequent railroad crossings. Japanese railways use obstruction detectors like these (the little tubes):

    Show

    If the crossing is clear this sign

    Show
    lights up, letting the train driver know it is safe to continue. I believe if you intentionally disrupt the crossing you can be fined. This information may not be entirely accurate but it appears to be the case.

    Here's a video on how crossings work in Japan.

    Other things to point out:

    -There are extensive grade crossings along the Brightline route and FDOT is absolutely car brained to the point of sheer lunacy, making grade separation something that should absolutely happen on this corridor

    -None of this excuses the foolish actions of the fire truck driver

    This tech apparently exists, and is in place in a few experimental crossings in Europe. It doesn't substitute the barriers, but makes sure that no one got stuck between the barriers.

    Although we have less of them, and they're more overworked, we have humans operating the trains who do that.

    I recently saw a clip of a person on a mobility scooter driving around the gates at a train crossing. I was seriously impressed with how much the train was able to slow down. Totally saved that persons's life.

    It takes miles for a train to stop. It's only be conceivably useful if someone say, broke down in the crossing at the exact time for that to work.

      Not to blame the victim in that situation, but try and go into a train crossing with enough momentum that you don't need your engine to work to get out.
