bill937ca Posted May 26, 2017 Share Posted May 26, 2017 (edited) Chikizuki video of grade crossing repairs on the Tokyu Ikegami line. I believe the crossing arms are made of bamboo and that is why they can be cut with a knife. Something you don't see every day. Edited May 26, 2017 by bill937ca 1 Link to comment
Jcarlton Posted May 26, 2017 Share Posted May 26, 2017 That was a saw, not a knife. I think that the crossing gate rods are PVC, but to tell you the truth I've never looked that close when I had the opportunity. 1 Link to comment
Jcarlton Posted May 26, 2017 Share Posted May 26, 2017 Bamboo poles would be kind of cool though, but I suspect that they would break more often than the PVC poles do. Link to comment
railsquid Posted May 26, 2017 Share Posted May 26, 2017 Definitely some kind of plastic tubing. Wouldn't surprise me if bamboo was used in the dim and distant past though. Link to comment
cteno4 Posted May 27, 2017 Share Posted May 27, 2017 Yes plastic with that telescopic fit, nicely engineered to easily just replace the section broken and not have to replace the whole thing. Might have a wrap of fiberglass as just a thin wrap of that can stiffen plastic tubing a huge amount but still be pretty thin and tough but saw easily once you get started. The poles sag very little for the 10 - 12' reach of them! I too would guess that not too long in the distant past bamboo was used! Cheap and easily replaceable and strong! Loved the onsite storage locker for repair bits, that's brilliant, just send out a guy with a wrench and a pocket saw, dome! Cheers Jeff 1 Link to comment
railsquid Posted May 27, 2017 Share Posted May 27, 2017 According to Wikipedia: "遮断桿は主に竹が使われてきたが、近年では繊維強化プラスチック (FRP) を使ったものが主流となっている。" -> used to be from bamboo, now fibre-reinforced plastic. 2 Link to comment
westfalen Posted May 27, 2017 Share Posted May 27, 2017 I remember seeing plenty of bamboo crossing gates on past trips to Japan, wouldn't surprise me if there are still the odd one or two out in the sticks on some impoverished private line. 1 Link to comment
railsquid Posted May 27, 2017 Share Posted May 27, 2017 (edited) Here's one on the Meitetsu Tsushima Line: https://blogs.yahoo.co.jp/kimentension/40307733.html I must admit it's something I've never looked out for previously, but no doubt from now one, I'll be checking every level crossing boom I see...

kvp Posted May 27, 2017 Share Posted May 27, 2017 It seems to me they have repaced the whole crossing arm (this is why someone tightens the base mouning screws) but the new arm was too long so they had to shorten it. The other weathered one across was also cut and taped. These arms are relatively soft so if someone crashes into it or if it comes down on someone running under it, it breaks without causing too much damage. They also seem to be modular with twist lock so you can stack them, like some tent rods and and photo tripods i've seen. Link to comment

Funny how much that one sags. I've seen plenty back in the day where there was a small bracket for it to sit on. Speaking of crossings, are three any more that are lowered horizontally like they used to have west of Mitaka before they elevated the line?

Kiha66 Posted May 30, 2017 Share Posted May 30, 2017 Re watched the video, love the heavy rain! Most of my time in Japan was durring typhoon season, so it brings up a lot of memories. Hope the workers didn't get too wet. I'm surprised they didnt just leave the barrier down to fix it, but I guess enough trains came through that they never had to wait too long. Downside is now I really want a 7000 series, and kato is coming out with one later this year.... Noooo, now I have more trains to buy! Link to comment

VentureForth Posted May 30, 2017 Share Posted May 30, 2017 (edited) One was used until 2012 at Jingumae on the Meitetysu Nagoya Main Line. Cool! Google Maps still shows it, with the image from 2012, but only from the West. The image from the East shows the new road. I can totally see why they closed it. 8 tracks?!?

kvp Posted May 30, 2017 Share Posted May 30, 2017 Interesting! It looks like in the past you could access the platforms from the crossing, so people could actually stand between the tracks at the end of large platform. (there is a history view in street view mode, so you can walk across the old crossing if you rewind to 2012) ps: The station building from this side totally looks like an old greenmax kit...

Socimi Posted May 31, 2017 Share Posted May 31, 2017 Another horizontal wire-crossing was the famous curved one just before (or after) Keikyu-Kamata on the Handeda Airport Line. It was in use up into the 1990s, but then it was replaced with conventional barries. Video by sintosya At 11.35, taken in 1995 (even if it looks very 1960ish) Link to comment
