The railroad could fix the rails if needed and choose to run service again without gettin permission. You can't tell by 'out of service' if it needs fixing. > Then I would say it is still "railway=rail" sure, but "in service" and "out of service" are different, and it's fair to express this in the db somehow. For the verifiability zealots, if you watch the tracks for 4 weeks straight and see no trains, you can call it out of service. If you see a train, it's in service. >> "abandoned": this is a legal distinction, where ICC has approved >> abandonment. shown as dashed rails. tracks may or may not be >> present, but typically some track remnants.

I don't think we should give mappers who don't worry about the distinction a hard time, but it seems better to be able to express different states of reality and strive to get it right.
