Relevant standards for railway infrastructure installations
Standards in the railway sector perform several important functions:
Uniform standards make sure that all components and systems function safely and reliably. Standards also ensure that different parts and systems are compatible with each other. This makes it easier to maintain and replace components.
The following overview lists standards, directives and regulations that are particularly important for railway technology system operators.
