The actual field bakery wagon, based on which this model was made, served Czechoslovak legionnaires on the Trans-Siberian Railway in Russia between 1918 and 1920. According to one of the authors of the model, Colonel Josef Vavroch, a former army intendant of Czechoslovak units in Russia, the beginning of the use of train bakeries dates back to the spring of 1918 (the first one appeared in Pemza in April 1918). Soldiers used large freight cars to build the bakeries. The internal construction of the bakery was initially iron, covered with bricks. However, the iron ovens, manufactured in the company’s own workshops in Krasnoyarsk, did not prove successful, so brick ovens, lined with clay, were built. The furnace took about 2/5 of the car space and the remaining space was used for workshops and bread store. Well-built kilns lasted for a year and a half and small defects caused by shaking while driving or shifting would be repaired. Some train bakeries have travelled nearly eight thousand miles without serious repairs.
