I was able to use Chase Hyatt Visa chip & signature at Vienna metro (not train) and France regional train kiosks in September 2013. Using chipless cards at these kiosk locations resulted in failure. At a staffed train ticket office in Vienna it had to be swiped instead of pushed in to read its chip.
Zurich airport in April 2013 I was even able to use a chipless Chase Ink Bold MC at the train station kiosks there.
It doesn't hurt to set a PIN either because in certain countries (e.g. Romania) you need the PIN almost everywhere (including supermarkets). As posted above, transactions post as purchases and not cash advances when using PIN.
Sorry for the OT.
