Services were formed of 485-1500 series EMUs, and were the first limited express trains formed of electric multiple units to operate in Hokkaido. The 485 series EMUs proved to be unsuited to the harsh weather conditions of Hokkaido, with frequent cancellations, and were later replaced by new 781 series 6-car EMUs.
The typical 6-car formation was as shown below as of 25 June 1980, with car 1 at the Sapporo end.
