Terminology at UIC

The UIC Terminology Group strives to provide the railway sector with accurate, equivalent terms in as many languages as possible. For experts should focus on the technicalities of the projects and not struggle with language barriers.

The UIC Members are warmly invited to mandate a representative in the working group to ensure that their language is regularly updated in the RailLexic term bank. Concepts are investigated and validated with native experts under the guidance of the UIC terminologist. The aim is to facilitate multilingual communication at an international level.

The terminology unit at UIC also helps other departments relying on glossaries, particularly the working groups in charge of drafting International Railway Solutions (IRS). These collaborations are essential to provide material to the UIC Terminology Group and to develop the term bank.
