text: Hmm, I should have saved the link of the article about the railway crossing. The only one I can still find is from Banedanmark, which indicates that the line is not open for passenger or freight traffic: https://uk.banedanmark.dk/-/media/UkBane/Railway-Undertaking/Network-Statement/2019/Appendix-2019/3_1A-Railway-lines-in-Denmark.pdf (index of documents: https://uk.banedanmark.dk/Railway-Undertaking/Network-Statements/Network-Statement-2019 ).
  
  In fact, it looks like the Gedserremise will be running a few museum trains this summer from Nykøbing to Gedser: https://www.gedserremise.dk/togkorsel.html
  
  Here is a forum post from 2015 on that the northern part may be used for IC4 test rides: https://danskejernbaner.dk/vis.bane.php?BANE_ID=107
  
  So, while there is no normal use of the railway, it is still occasionally used for museum rides. But they need special permission each time, so railway=preserved is not really appropriate.
  
  It looks like this railway is in such an indeterminate state that OSM doesn't have a good tag for it.
