rullende

Rullende is a Norwegian adjective and present participle derived from the verb rulle, meaning to roll. It describes something that moves by rolling or is designed to roll, rather than slide or remain stationary. In Norwegian, rullende functions as a descriptive modifier in compounds and technical terms, and it can indicate ongoing action or state when used with a noun.

In railway and transport terminology, rullende materiell is the standard term for rolling stock—vehicles that operate on wheels on a fixed track, such as locomotives, passenger cars, and freight wagons. The concept is central to planning, maintenance, and regulation, distinguishing moving vehicles from fixed infrastructure like tracks, stations, and yards.

Beyond railways, the word appears in general technical language to describe rolling motion, wheel-based components, or mobile platforms. As with many present participles, its meaning shifts with context, but the core sense remains a state of movement achieved by rolling.

Cognate forms exist in other Scandinavian languages, notably Swedish rullande and Danish rullende, reflecting shared roots in the Germanic language family. The English equivalent is rolling. Related concepts include rolling motion, wheels, and rolling stock in transport contexts.
