How does #ÖBB manage to offer "express" trains that are slower than the regular ones, despite making fewer stops????

RJ with 2h 29min and RJX with 2h 34min.

This doesn't make any sense.
Even the tickets are more expensive for the RJX, despite taking longer.

Oh, and the same connection with #westbahn only takes 2h 22min

Why?
I mean, I know the locomotives have worse acceleration than the SMILEs of Westbahn, but why are the RJs slower than the RJXs?
And why charge more?

Does anyone know?
