If you've got your back to traffic, you've got about 6 seconds from the rail starting to rattle until the train is on you. Maybe less if it's an electric. They're sneaky quiet bastards when they're moving.

A train at 70mph or more isn't loud for very long before it hits you. If you have other background noise (road traffic, wind, headphones) you won't hear the first sounds of the rails and wires hissing. Also: thanks for the effortpost, Bozza!

I am glad I got to see this before I die. I... I had lost hope. Thanks for the great post. Are there plans to install LIDAR etc at the automated half barriers? I'd have thought these would be a priority given there is no checking at the moment.

The crossing at my local station has had a few incidents in recent years. Every couple of months, there's van parked up nearby (usually Network Rail, sometimes BTP) watching what's going on. I've mentioned it before, but there's a fairly large Eastern European workforce at the nearby 'business park' and having travelled around Eastern Europe, the way to cross a railway seems to be to amble across whenever you need to. I've seen people come into the station, jump down off the platform, cross the tracks and climb onto the other platform because the barriers are closed. The station has a subway. There's also a pub right next door to the station, but I'm sure that has nothing to do with it.

Sundayturks posted:If it's a windy day and a fast train, I can see how it might be possible to miss 'em. I recall a railway safety dude came to my school once and gave a presentation that was essentially "People are really, really stupid and trains are subtler than you might think coming around a bend at a hundred miles an hour." Mostly I remember that guy for grumping that if any of us were killed on the line, those short haircuts would mean he'd have to use two hands to pick up our dumb heads from the line we shouldn't have been on. People might walk across the same crossing a hundred times and never see a train. It's why it is (or at least used to be, not sure now) so much more common to be knocked over in residential suburbs than the middle of London.

People are literal idiots when it comes to level crossings, like many other road situations I suppose. I still remember one day when I was walking to get lunch and the gates were down. (For context, I'm in the middle of Vancouver.) I stood there waiting for the train to pass, and after about 90 seconds some people had gotten out of their cars to lift up the gates, a few cars drove through while the people held up the gate. The train came to a stop before the crossing, and I can only imagine they were in there yelling "What the gently caress are you people doing!" Then there's the few times I've almost been run over because there's a traffic signal right before the train tracks. People see the train gates go up and without thinking run the red light they're stopped at, while pedestrians and cyclists are crossing the road. less than three fucked around with this message at 08:20 on Aug 23, 2015 |

This reminds me of someone (can't remember where in the world this was) telling me the local traffic lights have to be phased really short, because if the locals are waiting at red for more than a few seconds they assume it's broken and just go for it. People are strangely impatient. Come to think of it (and not train related, sorry), what's the law on that, if you've been sitting at a broken traffic light for 15 minutes on red? Give up and turn around? I can't imagine a driver being let off a red light camera fine just because it's broken.

That's more likely to be an issue with temporary lights than permanent ones. I think those are more likely to turn off completely. BBC article posted:Common sense There are permanent red lights near me on busy roads that can take two loving minutes to change so obviously there has to be a fairly large margin of error there as well. Reporting it seems like a good way of covering your back, although I think red light cameras themselves are also fairly rare and are likely to be on busy roads anyway.

Interesting post. Didn't really know much about how the UK did their level crossings. I'm a train control systems engineer (that does some pure signalling stuff occasionally too) down here in Victoria and we don't use those LIDAR or RADAR crossings. A lot of predictors generally (in areas that aren't surrounded by other signalling infrastructure), but they're starting to get ripped out now too because of track contamination issues. A lot of axle counter crossings going in in regional areas (which lead to all kinds of axle counter reset issues). The big focus in the Metro areas is on grade separations though. The state government has thrown a few billion at removing "the 50 worst level crossings" in Melbourne and that's where most of the work will be over the next three years (until major construction on a new cross city tunnel begins).

As train crew one of the most annoying things is when people don't replace phones correctly at level crossings which results in trains being cautioned through. Never risk jumping one though, someone did it in our area to save himself 30 seconds in his Land Rover and was killed instantly by the 156 coming round the corner. Fun fact: one of my colleagues used to try and flush his early morning turd so it landed on the level crossing on a branch line that all the school kids and commuters would then have to walk past to board the train

spamman posted:Interesting post. Didn't really know much about how the UK did their level crossings. This is the bit that interests me here. I live and work in Aus in the signalling trade. What kind of contamination are you seeing with your predictors causing them to fail? Generally there are systems you can use to ensure good readings even on the moat disused lines (in WA there is a GCP4000 that operates well on a line that sees one train per year). Also what issues do you face with regards to resetting on remote crossings? Locals traversing the axle counters would be about the only situation that would be of any issue where you'd leave a track unable to non co-op reset.

In regards to track contamination, particular grasses grow over the tracks to the point where they won't drop, and there are also areas where there are millipede breeding seasons (I kid you not) where millions of them go over the tracks, get smooshed into a paste which then stops tracks from dropping. In terms of axle counters, bored kids in the country have figured out how to make heads think there has been a count and drop level crossings.

Have you done any testing with DC shunt enhancement panels? By feeding a 5v constant DC feed you can generally break through small portions of rail covering to provide a better shunt. The other option to consider on those lines might be using Jeumont Schneiders (or TI.21 depending on your upbringing). It's hard to not significantly shunt a 500V pulse but you'd end up having to sacrifice distance and put in multiple tracks on each approach. With axle counters and kids you're pretty much hosed unless you can build a plastic housing to stop it. Should be possible with most Frauschers and Thales but not so with Siemens given their size. Getting approval for it on the other hand...

The option they've used so far is HVI track circuits in small doses. Not sure actually on the axle counters (like I said, I'm normally train control so I wasn't too involved with it), from memory though the Siemens axle counters are the only ones type approved currently by this ARO.

Can any UK train goons shed any light on these mysterious card readers? This one is at Andover station, but I'm sure I've seen them at other stations up and down the Waterloo-Exeter line. They are all 'out of service' and have been ever since I moved to the area about 4 years ago so I've never seen anyone use them, and I pass through the station at peak and off-peak times several days per week. What's their story?

Bozza posted:The Fraucher ones? I like those they're pretty neat but from a maintenance technician perspective I'd prefer the Azlm types. The Thales Azlms are good don't get me wrong but the Frauschers are a maintainers dream. They are effectively now just plug and play once setup. If you drop them off the rail for track works you can throw them on, ensure the height is right (which 99 times in 100 it will be because of how the claw is fitted) and then have it automatically recalibrate. Add into that the Frauscher development into high rail detection being at the best level it ever has been and I prefer them over all other types. The big downfall and the reason we won't see full use of axle counters will always be the lack of broken rail detection, we as an industry haven't yet tried the workarounds to see how well they work. For instance a DC track (or high gain coded tracks) can work under an axle counter as a non-vital broken rail checking system. spamman posted:The option they've used so far is HVI track circuits in small doses.
