Hi Brickblock1, it looks like the ids you removed are indeed not UIC codes, but eva ids. I believe we should still keep those ids (if not under the uic_ref using the ref:eva key) if no other is provided (e.g. Bredsjö station) , as they are essential to establish any reference in the systems to add uic codes again etc. I currently prepare a tool to review and correct station ids based on a db api and the Trafiklab dataset you referenced.
