If the tracks are gone, I tag it railway=abandoned. If the tracks are still there, I tag it railway=disused, even if it's disconnected from the main line. Railroads in New York will *often* disconnect tracks they aren't currently using because tracks connected to the national rail network are taxed at a higher rate. Of course, land with no tracks at all is taxed even lower, so rails quickly get ripped up here. Have I ever said how much I hate the greedy hand of government? I much prefer the invisible hand of markets. Invisible hands don't levy taxes and cause tracks to be unnecessarily ripped up!!! -- --my blog is athttp://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] level_crossing, leveled
True, but it might well derail a locomotive in the winter. I once saw a locomotive derailed by mud that had flowed across the track, then frozen.. Fortunately, the locomotive was moving slowly enough that it didn't cause a catastrophic accident.

IMX it only takes a year or so for a disused railway, often called OOU in the UK ("out of use"), to become unsuitable for trains to "turn up and go". On occasion the problem is just a bit of overgrowth, but more frequently, there'll be something serious that needs addressing before trains can pass again: signalling, skewed or stolen rails, washed-out trackbed. A bit of tarmac across the rails is probably the least of these problems. So, given that "disused" means "permanent way still largely in place but some work required to get it back in place", I'd be tempted to stick with railway=disused even despite the odd bit of tarmac. (The example that springs to mind most readily in the UK is the Amlwch branch, for those who know it.) cheers Richard -- View this message in context: http://gis.638310.n2.nabble.com/level-crossing-leveled-tp6404088p6406306.html Sent from the General Discussion mailing list archive at Nabble.com. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I hit this when I first started mapping, there is a lot of track about the place, and the crossings are still there, but tarred over, rather than ripped up. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Unless you operate to peculiar safety standards, there'll probably be a stop sign on the track some way either side of the former crossing(probably set for the stopping distance of the heaviest train operating at linespeed, and taking the gradient into account - which could easily be a mile away). So there'll be quite a length of track that's "disused". I'd probably tag the railway as abandoned, and remove the level crossing, if it looks like a permanent situation. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I usually have the disused raily intersect the road but don't tag a level_crossing on the intersection. In some cases (where the tracks have been torn up rather than just paved over), I'll split the railway into three pieces and tag the part that crosses the road as abandoned rather than disused. -- ...computer contrarian of the first order... / http://aperiodic.net/phil/ PGP: 026A27F2 print: D200 5BDB FC4B B24A 9248 9F7A 4322 2D22 026A 27F2 --- -- When you say "I wrote a program that crashed Windows", people just stare at you blankly and say "Hey, I got those with the system, *for free*". -- Linus Torvalds --- -- ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

[OSM-talk] level_crossing, leveled
HI all, What should be done with a level_crossing, when trains may cross no longer? The junction was a level_crossing, but has been repaved and re-sculpted. The rails are now covered by 0.3 - 0.4 m of asphalt which appears to have been laid directly over the tracks. So the railway hardware appears to still be there, but unusable. The rails continue both directions from the level_crossing. To this point, I have left the level_crossing tag in place; it can still serve as a waypoint, I suppose. Any thoughts or widely accepted customs regarding this? ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
