The two German Class 04 steam locomotive
s were experimental engines with the Deutsche Reichsbahn
, that were derived from the Class 03
standard locomotives (Einheitslok

overpressure
s from 156.9 N/cm² to 245.1 N/cm² by using high-tensile steel
. These vehicles, built by the firm of Krupp
, soon showed signs of damage on the firebox however. Because the engines did not meet expectations even after modification and repairs, in 1935 the pressure was reduced to 156.9 N/cm² again and they were given operating numbers 02 101 and 02 102. Due to a lack of water the boiler on 02 101 exploded on 3 April 1939; after that both engines were retired and eventually scrapped in 1940.
The engines were equipped with a 2'2' T 32 standard tender

Steel
Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten...

Tender locomotive
A tender or coal-car is a special rail vehicle hauled by a steam locomotive containing the locomotive's fuel and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so tenders are necessary to keep the locomotive running over long distances. A locomotive...
