The German term Donnerbüchse (plural: Donnerbüchsen formerly Donnerwagen) means 'thunderbox' and is the nickname for the four-wheeled, open, passenger coaches, built from 1921 onwards, that served with the Deutsche Reichsbahn

Deutsche Reichsbahn-Gesellschaft

The Deutsche Reichsbahn – was the name of the German national railway created from the railways of the individual states of the German Empire following the end of World War I....

. In contrast to their predecessors, they were made entirely of iron or steel. The name comes from the loud rumbling of these coaches as a result of their lack of damping. Even the immediate forerunners of these wagons were given the name despite their wooden construction. In the early days, they were also called Ackermann'sche Donnerbüchse ('Ackermann's thunderboxes') after the departmental head responsible for them in the Ministry of Transport.

History

Because the Deutsche Reichsbahn suffered from a great shortage of coaches following the ceasefire reparations

 at the beginning of the 1920s, in 1921 new passenger coaches were built based on standard designs, the so-called Einheitsbauart. Although a steel design was called for from the outset, most of the coach factories could not immediately change their production lines, so that the vast majority of the coaches in the first delivery batches were still built with wooden coach bodies. Between 1921 and 1923, 90 iron and 2,639 wooden coaches entered service. Whilst the wooden variants were exclusively built as 4th class coaches, the iron ones were delivered as 2nd, 3rd, 4th, 2nd/3rd and even 2nd/4th class coaches.

In a succession of procurement programmes, a further 517 4th class, all-steel coaches (440 in Austauschbauart

form) were acquired in 1927/28, followed by a total of 5,009 coaches of 2nd, 3rd, 4th, 2nd/3rd and 3rd/4th classes (of which 3,377 were Austauschbauart versions) from 1928 to 1930, so that by 1930 more than 8,250 coaches had entered service. In 1928, when the Reichsbahn dropped the 4th class grade of accommodation, the 4th class coaches, which had initially been the largest group, were redesignated as 3rd class coaches at first and then, later, converted.

In addition to the passenger coaches, 917 Pwi luggage vans

Conversions and operation

From 1930 several Di-21 coaches were converted to heavy hand luggage vans (Traglastenwagen).

In 1930 and 1934, 28 Cid-21/21a coaches had simple post compartments fitted, they were designated as class C Postid-21/34 and, later, as B Postid-21/34.

In 1951 several Ci coaches were converted into driving trailers (CPwif) for shuttle services headed by steam locomotive

s. They had a driver's cab fitted at one end, were given red livery and a luggage compartment.

At the beginning of the 1960s the retirement of the Donnerbüchsen began; however many were converted to works coaches (Bauzugwagen) and used as such. The Bundesbahn used the last coaches in passenger services at the end of the 1970s. These coaches are still working today on many museum railways.
