What route is the direct Paris - Berlin ICE 9591 taking on 25 June? 🤔

There are 5 hours timetabled for Frankfurt (Main) Hbf - Südkreuz, and no interim stops

You can go via Göttingen, with interim stops, faster

ICE 838 (Sprinter) on the same day does it in 3h 44 mins, direct to Südkreuz (i.e. via Erfurt)
