​The Agency cooperates with NB-RAIL – the coordination group of notified bodies for railway products and systems established in accordance to the art 28(5) of the Interoperability Directive 2008/57.

The notified bodies are independent organisations responsible for assessing the conformity of interoperability constituents and subsystems regarding the requirements of the TSIs.
The Interoperability Unit cooperates with NB-Rail to collect feedback on the exercise of their duties and propose and promote appropriate improvements.
The NB-Rail representatives are also active in the ERA "Conformity Survey Group" (CSG), a group specifically established to discuss about the conformance part of the TSIs.
ERA is also invited as observer at the NB-Rail meetings (plenary, strategic and subgroup).
