I photographed the locomotive Taurus OBB: E-190-018 (1216 018) long operating between Austria, Germany and Italy and now has received the new livery "Railjet"
This suggests that the services "Railjet" should reach Italy in a not too distant future, you will be prepared as soon as the carriages.
The OBB-Railjet train travels regularly if I'm not mistaken by some years in Austria, Germany, Switzerland and Hungary.
