text: > @Mateusz Konieczny, why do you not add rendering of service=crossover as gray rails? :)
  
  It is on my TODO list, unfortunately recently I was too busy work on openstreetmap-carto. One note - in changes like this changing rendering to make service=crossover gray is easy. The tricky part is ensuring that nothing will be broken (to avoid problems like https://github.com/gravitystorm/openstreetmap-carto/issues/1442 ).
