[Q]: I'm landing at Vienna airport on a Friday (work day) at 17h35 and I'm supposed to attend a meeting at 19h00 close to Stephansplatz in the 1st district. I have only carry-on luggage and an EU passport, flying in from a Schengen country, so I should be out shortly after 18h00.

What is the fastest public transport into the city center taking into account it is rush hour? 

I'd like to be on-time to surprise my colleges at the meeting, who already started picking, like "don't worry we'll wait for you"

[A]: Fastest public transport from Vienna airport into city center?


[Q]: Following this question, I had a refused entry in the UK before (about two years ago) and granted a temporary admission.

I am just curious, what does this stamp below mean? (there two stamps, what I am asking is the top stamp). What is this 45 XXX on the stamp for? I can hardly see any readable word on the stamp!



When I left EU via Amsterdam, the officer asked me what that is and I could not answer him. So I just told him that it was the date I left the UK.

Any ideas?

EDIT: Sorry I think the code/ number should not be shown in this public space. 

[A]: Entry Refusal - what does this stamp mean?


[Q]: I am buying a train ticket from Paris to Düsseldorf (Thalys). Can I hop off in Köln to spend sometime and then hop on an RE (regional train) on the same day (within half of a day)? Or do I have to buy a separate tickets? I know I cannot board the Thalys again, because it requires a seat reservation.
