1st to 3rd class corridor train coach, "Danzig 0674", 1:5 scale model 1st to 3rd class corridor train coach, Comparative size of the model

Starting in 1903, the Prussian State Railways purchased 23 corridor train coaches to serve as through coaches, each of which accommodated three classes: a four-seat first class compartment, three six-seat 2nd class compartments and three eight-seat 3rd-class compartments. There was also a service compartment as well as one lavatory each for women and men. The Breslauer Actien-Gesellschaft (Corporation) for Railway Supplies delivered the "Danzig 0674" coach in 1904 for the price of 44,103 Marks. The manufacturer donated a model of the coach to the Berlin Transport and Building Museum in 1906.

A size comparison with a pen makes the dimensions of the model clear.
