>>1902426>>1902624Currently platforms 1(eastmost) through 4 are used for local trains(both JR and Donan), 5 & 6 are used for Hakodate Liner, and 7 & 8(westmost) for Hokuto. The longest platforms are on the west. However this poses a problem, since the east track would be the one converted to standard gauge, since it only crosses the track to the snowplough shed at Goryokaku(which could be moved to space saved by not needing as many local trains), as opposed to literally every other crossing being on the west track. The station would likely be rebuilt to avoid crossing at the station itself. We then have two options(going from eastmost platform)
>local trains on narrow gauge(presumably operated by Donan)Two or maybe three long standard gauge platforms for Shinkansen, three or four shorter narrow gauge platforms for local trains and one long narrow gauge platform for the ocassional Shiki-shima and the likes(unless they make it stop at Goryokaku).
>local trains on standard gauge(operated by JR)Two or maybe three long standard gauge platforms for Shinkansen, two shorter standard gauge platforms for JR local trains, and two or three narrow gauge platforms for Dounan local trains with one accomodating for Shiki-shima.
