Mark train line/networks assigned to a station with refuel icon
In a recent issue reported on discord, a user had inadvertently assigned a station intended for cargo distribution, as a fuel station for the same network. Only through carefully checking the large train network list was it possible to identify the misatrribution.
It could helpful if the train line / networks assigned to and viewed from a station could include a refuel icon beside them where they have been marked as a refuel stop.
If assigned as both cargo and refuel, opt to exclude the refuel icon or perhaps include a + refuel icon to indicate it does both.
