This is a B Train Shorty model.
This "Girls und Panzer" themed model train set is part of Bandai's "B-Train Shorty" train model kit lineup, with realistically depicted train cars at about half their usual length. This set spotlights markings used on the Kashima Rinkai Railway 6000, and comes with one No. 2 car (with a different design than the one released in 2014), one No. 3 car, a tank and tank wagon, and two figures (a full-body figure and a half-body to ride inside the tank). It can be converted to be compatible with N-gauge train sets by installing an optional power unit 3 and traveling carriage T (not included). Don't miss it!
