Thoroughly times out on my computer... unviewable. This is in browser with the standard Carto map. Tried in JOSM asking for all member as it initially shows as loaded 'incomplete'. Same, times out. Yes you can add members piece by piece and now it's a major pain to anyone who ever is going to try to change an element anywhere along the line.

Corridor: A railway corridor is the area reserved by the railway companies upon which the rail, stations, emplacements etc are positioned. I've mapped a view miles but only as filler in urban areas.
