+1, but something that is 100% gone can be deleted.

I have seen railway=abandoned mapped across open-pit mine that was there for 20 
years.

There was zero chance of mappers recreating it (as oldest aerials will show 
open pit mine),
it was 100% gone (like embankments, railway station and dirt 20 m below).

I deleted it.

Something that is fully, completely and totally gone can be deleted. If there 
are buildings
across former track of the railway and embankment is leveled then it can and 
should
be deleted.

If there are no traces whatsoever and you need old maps to map it then it is 
out of
scope of OSM and deleting it improves OpenStreetMap.

There was railway here:

There are no traces whatsoever. It is not mapped, should not be mapped and
should be deleted if mapped.

I have more doubts about cases where only earthworks remain (and are used for
cycleway/road/path). You can plausibly guess that railway was there but it is 
just a
guess and typically you need old maps to confirm that it was there.

And in some cases such features look like former railway but that is not really 
true.

But something that is totally gone should be gone from OpenStreetMap (with 
exceptions
for objects marked as gone and temporarily not deleted to prevent incorrect 
remapping).
