Separate Historic and classic train coverage map (key Touristic Heritage)

Sometimes proposed on discord, but doesn't have a FR, separate actual train coverage map in 2. Classic everyday trains in one side, and all heritage in the other (heritage tram, heritage metro, heritage train), even if the line haven't a fixed schedule (current criteria to be displayed on coverage map) Could allow people to easily see that there is a touristic train here and they should go visit & give them money. (Was also thinking of putting pins for rail museum on the map, but how do you validate them ? Or a link to an OSM uMap ?) As discussed on discord, - "I would prefer the coverage map stay the way it is now, or if they're going to be separated, retain another "total" coverage map" - "could have a Grand total, or heritage could be a 'subdivision' of country like any region (loosing the idea of 100% without having to go to all Heritage Train)"
