Okay can someone explain this clearly to me:
I want to do FRA-QKL (Cologne rail station).
So I catch the train at FRA, where I "check in" - no problems so far. DO I automatically get checked in for the QKL-FRA segment as well?
Also, I am actually planning on nesting a few of these, meaning that some of the runs will have to start in QKL. Are there "check in" facilities there that are operated by LH? Or will I run into trouble?
I appreciate any clarification you can give me.
