Hallo Glassman, thank you for your message. The entire changeset is based on data from the official website of hellenictrain.gr The int_name=Epivatikos Stathmos was wrong and I corrected it to int_name=Thesssaloniki, the name:xx are not in wikipedia and therefore deleted. It was consensed by the greek community that if the control is too much work, we can first make a fast change and leave the control for later https://community.openstreetmap.org/t/mass-edits-name-el/126067/65
