>>2018971I was going to say that it may be rescued by all the UBE corporation stuff in Mine, but apparently they made their own private road(see map), including roadway crossings:

So as long as they won't be hindered by bus driver shortages, It might not make sense to rebuild the line.
>>2018833That bit(Nagatoshi - Kogushi), as well as the bit directly before it (Matsuda - Nagatoshi) apparently have about 200 transportation density. That's 140 kilometers at a level where JR Hokkaido openly invites the municipalities to discuss closure. While the only lines JR West closed are Sanko line(48 transportation density) and Miki line(50 transportation density) and they are keeping around the Kisuki line(255-72 depending on section), I doubt they'll be in a hurry to fix it, especially since I remember reading that significant river control work would be required.
