@cstross Have to wonder what's going to show up to tow it.
@graydon Just adding that "can't park there, mate" has become a catch-phrase on /r/Edinburgh, usually relating to photos of cars with drivers who blindly followed their Satnav and drove onto the top of a staircase …

@cstross Got that bit!

Parts of the western US there are are active freight lines down city streets plus there are semi-fossil rights-of-way still on streets that are not used very often but the clearances are maintained against the day. This looks like one of those; someone missed a switch, and it's very possible that they really don't want to run the whole freight wherever this bit of track is going. ("The factory that was there closed down in 2003" sorts of circumstances.)

@graydon @cstross There's a spot in Cambridge MA where a rail line (used to, before it got railtrailed) crossed the busiest/worst rotary in town (possibly in state) - before it closed, it had one user, a 2x/year corn syrup tanker delivery for a bread company. They just had police cars show up and block the intersection for the crossing rather than expect zoned-out commuters to handle the signals sanely :-)
