- A large 31ft wing container U55A is newly produced. The U54A, which has almost the same shape, reproduces the differences in markings and stripe colors. As with the actual vehicle, the KoKi 105 reproduces the formation in which U54A and U55A containers are mixed.
- The "Ecoliner" logo painted large on the side of the container and Nippon Express's current logo "NX" are accurately reproduced.
- The difference in color (gray) in the center of the top of the container, and the stripe color and pattern on the top of the side and end are reproduced.
- Different positions of the non-standard mark (Hello mark) are created for the 10-car set and single items.
- A new 2-car KoKi 105 container freight car is produced as a unit (even-numbered cars are reused from odd-numbered cars, so some specifications differ from the actual vehicle).
- The KoKi 105 reproduces the frame shape in detail, with details such as piping visible on the frame with a missing floor.
- A reflector is included to be attached to the end of the formation.
