Hi there! Quick question for my fellow rail-fans here...

I'm arriving in Köln HBf on the Thalys and scheduled to depart on DB CityNightLine 43 minutes later. Any tips for how to keep this going smoothly? I've been through large HBfs before but never to catch an international departure, so I'm wondering if there's anything different I should be preparing for.

Oh, one other quick question. I bought my DB ticket over the internet and printed it on my American 8.5x11 paper. It says to print it on A4 paper, which is nearly identical. Are their barcode readers sufficiently flexible that 8.5x11 will be alright?

Thanks in advance!
