Wengen to Jungfraujoch using Swiss Travel Pass

[gprabhutx]

I will be staying in Wengen.  I will be using Swiss Travel Pass for travel.  Looking at the train schedule, Wengen to Kleine Scheidegg, change train to go to Eigergletscher and then take another train to go to Jungfraujoch.  Looks like I just need to reserve seats between Eigergletscher to Jungfraujoch.  Is that correct?

Thank you for your question. 

Seat reservations are recommendend, although not mandatory.
