This is a strawman, since there will rarely be more than one former line
across a small area. Correct me if I'm wrong, but I don't think anyone
wants to map all the former second tracks, sidings, and such, especially
where they've changed over the years.
I am of course one mapper who's been mapping former railways. (Russ
Nelson is another.) There is certainly value in seeing how the current
disconnected bits of railway infrastructure used to connect. I've also
mapped the occasional highway=abandoned, e.g. where the old road was cut
off by the Interstate.
I have no major objection to using the dismantled tag, and will only
change it to abandoned if there clearly are traces remaining. But I
personally won't use it, since the line is too subjective. For example,
is this abandoned or dismantled:
Note the switch stand being used as a mailbox. But the actual grade
isn't much more than a typical property line.
