The C IV was a steam locomotive

Steam locomotive

A steam locomotive is a railway locomotive that produces its power through a steam engine. These locomotives are fueled by burning some combustible material, usually coal, wood or oil, to produce steam in a boiler, which drives the steam engine...

Royal Bavarian State Railways

As a nation-state, Germany did not come into being until the creation of the German Empire in 1871 from the various German-speaking states such as Prussia, Bavaria, Saxony, Baden and Württemberg. By then each of the major states had formed its own state railway and these continued to remain...

Compound locomotive

A compound engine unit is a type of steam engine where steam is expanded in two or more stages.A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger...

, designated as Class 53.80-81 and allocated the operating numbers 53 8011 to 8064 and 53 8081 to 8168. The two-cylinder engines were retired by 1926, the compound variants in this class by 1931.

The original locomotives were equipped with Bavarian 3 T 10.2 tenders; the compound engines had Bavarian 3 T 10.5 tenders.
