context_page_description: Under the Whyte notation for the classification of steam locomotives, 0-10-0 represents the wheel arrangement of no leading wheels, ten powered and coupled driving wheels on five axles and no trailing wheels. In the United Kingdom, this type is known as a Decapod, a name which is applied to 2-10-0 types in the United States.
context_section_description: The 0-10-0 type was the principal standard freight locomotive in Russia and was manufactured in very large numbers. The E class (Cyrillic Э, not to be confused with Е-class), freight locomotive was made up of several sub-classes, all developed from the same original basic machine. The sub-classes included E, Em, Eg, Esh, Eu, and Er.
  A number of both the Em and Eg class received condensing tenders for working in areas where water supplies were scarce. These were designated Emk and Egk class respectively. However, these locomotives were experimental and the condensing tender was mainly used on the 2-10-0 SO19-series locomotive.
  The E class was the most numerous single class of locomotive in the world, with around 11,000 manufactured in Russia and other countries such as Czechoslovakia, Germany, Sweden, Hungary and Poland. This class even far outnumbered the German DRB Class 52 2-10-0 Kriegslok. The class was eventually superseded by the SO class 2-10-0 which can be considered a further development of the E class, the L class 2-10-0 and the FD class 2-10-2. Despite being superseded, it was not replaced, and the class was widely used until the end of steam in Russia.
