Fodor's Travel Talk Forums - Storage lockers at Hamburg HBF Station?

Hello, can someone please tell me if there are *reliable* storage lockers at Hamburg HBF Station?

We are going to be arriving today and need to store our luggage (two large suitcases that are about 27"ish tall, and a couple backpacks) right at Hamburg station, if possible. We're having trouble determining if there are reliable and perpetually available lockers right at the station that could handle storing our luggage for a few hours.

Can someone please let me know if there's something like this at Hamburg HBF, please? Thank you!
