Machine translation, like DeepL or Google Translate, is a useful starting point for translations, but translators must follow the LLM translation guideline, revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article.

Regionalbahn trains usually call at all stations on a given line, with the exception of RB trains within S-Bahn networks - these may only call at selected stations. Thus, they rank below the Regional-Express train, which regularly stops only at selected stations on its route.[1]
There is no obligation to use the term Regionalbahn for basic local services; some private rail operators therefore use their own names to denote their trains.
Stock
RB services make use of vastly different types of rolling stock; on electrified lines, double-deck cars or EMUs may be used, DMUs like the Bombardier Talent.
