According to the wiki demolished:railway=rail seems to be preferred https://wiki.openstreetmap.org/wiki/Key:razed:railway

I've updated them, but this should just be temporary, and the lines completely deleted when new photos are available. Quote:

"OSM is for features existing on the ground. This tag, however, is useful for preventing other mappers from inadvertently remapping demolished features that are still visible in aerial/satellite imagery currently available in OSM editors. "
