Introduced in 1953 with a two-stage link structure, rather than the single-stage link structure of the WAM23000, this is a representative two-axle covered freight car alongside the WAM80000 and WARA1.

Some pre-war WAM23000 cars had no ribs on the side doors, and even after being converted to the WAM90000, the ribless doors remained.

Features

• The WAM90000 series, which has no ribs on the side doors, is reproduced using a separate mold
• The underfloor is filled with detail thanks to the brake lever and step reproduction
• Various white markings are printed on the black exterior
• Car number is printed
• Silver wheels are used
• Can pass through mini curves (when connected to a locomotive capable of passing through mini curves)
