I will be doing a 'blitz' tour of the rhine in mid-august. I would like to leave the bulk of my luggage at the Cologne train station and just take a day pack with me. Is it possible to leave luggage at the Cologne train station for two consecutive days including overnight, and if so what is the cost? Thanks
There is an automated luggage storage system in the West, D Passage of the Köln Hbf. You can leave your luggage with it for 24 hours for 5€/day, but I'm not sure if it is for more that 24 hours. However, there is a "left luggage" room in the SW corner of the Bahnhof, near the door nearest the Cathedral. https://cms-bahnhof.noncd-web.db.de/sites/default/files/pdf/koelnplandb_vst_1013.pdf
