kolejowego

Kolejowego is the genitive singular form of the Polish adjective kolejowy, which means related to the railway or railway transport. The base form kolejowy is used to describe nouns connected with railways, such as infrastructure, equipment, and industry. Like other adjectives in Polish, kolejowy declines for gender, number, and case, so its genitive masculine/neuter singular form is kolejowego, while feminine genitive singular is kolejowej.

In practice, kolejowego appears in phrases where a masculine or neuter noun is in the genitive case. For example: pociągu kolejowego (of a railway locomotive) and kosztów kolejowego utrzymania (costs of railway maintenance). It also participates in compound expressions such as tabor kolejowy (rail rolling stock) in which the adjective agrees with the head noun, though the head noun is in the nominative or other cases.

Common usage and contexts: the term is widespread in technical, industrial, and legislative texts dealing with rail transport, including descriptions of railway infrastructure, rolling stock, and services. It forms part of standard vocabulary for discussing rail networks, safety standards, and planning documents, and appears alongside other railway-specific terms like kolejowy system, koleje, and infrastruktura kolejowa.

Etymology and relation: kolejowy derives from the noun kolej (railway) with the adjectival suffix -owy. It is closely related to related forms such as kolejowy (masculine nominative) and kolejowej (feminine genitive), all expressing association with rail transport.
