On ÖBB,  the train number which runs Innsbruck Hbf > Salzburg Hbf on Fri, Apr 29 2022 10:17 - 12:03  is Railjet Xpress 161 + Railjet Xpress 184. And I would like to take this RailJet train. I cannot find the exact same train number in Rail Planner. The Planner shows the train EC 161. So I am wondering if it  is the same train? The EC 161 train is scheduled at exactly the same time but it is a different train number.  And what should I do to add a journey in this case ? 

Thank you in advance for your help.
