(Continued from Part 1.)
Railroad tracks are another possible route that you could use to get home, but doing so can potentially be very dangerous – unless you’re in a grid-down scenario and you’re absolutely sure trains aren’t running then I strongly recommend you avoid them. If you can use them safely they could provide a possible route that’s typically isolated and free from obstacles. Railroad bridges are potentially less likely to be monitored or blocked, so if you need to cross a terrain feature like a river or steep gully while avoiding contact they may be a better option than road bridges. OSM and ORS do show railroad tracks as alternating white/black dashed lines is you zoom in enough, but they’re hard to identify on a wider-scale view.
A better alternative is to use the OpenRailwayMap (ORM) map, which uses color-coding to show pretty much every railroad track around the world on top of a gray-scale map. Keep in mind that the spacing on railroad ties can make it very difficult to match your stride for a comfortable walk, so you’re better off if you can find tracks with a wide right-of-way next to them. Since you’re never supposed to walk on them no available route planning software will include them in a possible route plan – when I’m route planning I’ll usually include a separate screen clip showing the major rail lines that I could use as alternate routes if the situation warrants it.Continue reading“Follow the Yellow Brick Road – Part 2, by J.M.”
