The "Yuzuru" was the second sleeper limited express which started its operation from Ueno station in October, 1965. Then the AC electrified track was still under extension on the Joban line. So the C62 steam locomotive pulled the "Yuzuru" between the un-electrified area between Taira and Sendai. 

Meanwhile, the "Hakutsuru" was the first sleeper limited express departing from Ueno which made the debut in October, 1984, one year prior to the "Yuzuru". The train traveled between Ueno and Tokyo via the Tohoku line, combining a rare coach with seats NAHA 20. "Hakutsuru" started operation with series 583 in 1968 by replacing and transferring series 20 used for "Hakutsuru".

Be sure to order the EF80 engine that pulls these cars, 3811-3064-2.
