The EF81 is a renowned AC/DC electric locomotive that debuted in 1968, representing Japan National Railways. Even after the transition to JR, it has been a versatile vehicle for both passenger and freight services. Notably, the EF81 locomotives belonging to the JR East Aomori and Nagaoka vehicle centers feature a distinctive body painted in red No. 2 and equipped with a visor above the front windows (Icicle Cutter). In recent years, the couplers have been replaced with dual-head couplers, enabling the locomotive to haul EMUs directly in addition to passenger cars, and it also transports new carriages and retired ones for delivery trains. It continues to play an active role today, pulling special trains like the "Cassiopeia Cruise" and "Cassiopeia Journey" limited express sleeper trains.
