① A passenger train formation set that allows you to enjoy the night express trains of the 1970s, consisting of a 20-series sleeping car, a 12-series express passenger car, a mail car, and a baggage car.

② In addition to this product, you can enjoy a full formation just like the real train by combining the "12-series express passenger car JNR specification" set and various single items.
③ The Nahanef 22 and Nahane 20 express trains "Kaimon" and "Nichinan" reproduce the appearance of two stripes with the cream No. 1 thin stripe omitted from the fascia board.
④ The Nahanef 22 and Nahane 20 reproduce the form in which the sleeping car sign above the passenger door is filled in. The car number is also reproduced in white letters.
⑤ The back sign of Nahanef 22 is already installed with "express". The "Kaimon" and "Nichinan" sets come with replacement "Kaimon" and "Nichinan" (illustration) back signs.
⑥ Mani 50 and Suyuni 50 reproduce the body shape and large double-opening side doors based on the 50 series passenger cars.
⑦ Oyu 14 is a 200 series car called the East Gate Special Car, which has few classification shelves. *The actual car is the 0 series, so it is a substitute.
⑧ The tail lights/back signs of Nahanef 22 light up. Suyuni 50, Mani 50, and Oyu 14 light up the tail lights (with a switch to turn them off).
⑨ For the couplers of each car, see the set configuration diagram.
⑩ Each product comes with a destination display sticker, a lettering sheet for changing the car number and affiliation notation for the 12 series, and a coupler for the end of the Suhafu 12.
