Limited Express Trains in Kisei Main Line consist of "Ocean Arrow","Kuroshio" ,and "Super Kuroshio".
Because the 381series train used as "Kuroshio" or "Super Kuroshio" has run the long life since electrification of Kisei Main Line(west side of Shingu), it needs to be replced in the near future.
These days, JR west released information about the train alternates 381series train
The design of 287series train is said to be like that of 681series train.
I don't understand why pendulum function*1 won't be attached to 287series train.
*1:The device to maintain center of gravity of train, when train runs at curve.
