We don't generally map features that no longer exist and have been replaced/built over by new features.

Specifically, I can say with 100% certainty that this feature does not exist, if it ever did.  There is no remnants of rail, ties, signals, etc.  There also are no railways visible on aerial imagery where one could be confused about it being seen on old imagery and where we don't want it readded.

Abandoned features should also have some trace remaining.  So segments that go across a motorway where nothing exists shouldn't be mapped either.
