Background and overview
683-2000 series used on "Shirasagi" intercity services linking
Nagano and Kanazawa were displaced with 681 series trainsets after the
start of the operations on the Hokuriku Shinkansen. Because of this, JR
West converted surplus 683-2000 series into intercity DC electric multiple
unit classified into 289 series in order to displace superannuated 381-0
series EMU used on "Kuroshio" and 381-1000 series used on "Kounotori",
"Kinosaki2, and "Hashidate" intercity services in 2015.
7 trailer intermediate vehicles, class saha683-2500, were plucked out from
7 five-car set to form 7 four-car sets for "Kounotori", "Kinosaki",
and "Hashidate" intercity services. Then 5 surplus trailer intermediate
vehicles, class saha683-2500, plucked out from five-car sets were inserted
into other five-car sets to form 5 six-car sets for "Kuroshio"
intercity services.

On the other hand, vehicles for "Kounotori", "Kinosaki", and "Hashidate" is painted in white with gray wide band around side windows, and dark red narrow band under side windows.
