Flying Lawyer is correct, you definitely need a ticket on there.
Just out of curiosity: has anybody ever been checked for tickets on there??
I used this one for two years straight every work day, once in the morning, once at night and a couple of times since then (when I travelled ex DUS and didn't take S11 into the terminal) and never got bothered once.
