If it's Vindobona, OeBB and CD give that moniker to RailJet trains that run between Vienna and Czechia (mainly Prague) with some of the CD trains going on to Berlin. Might nt be the same experience as far as dinign cars go. Reputedly the food on CD RJs are better than on OeBB ones (ridden in BC on both, and dined onboard the past 2+ years). With forewarning, only ordered what would reheat well on the OeBB train.

Trans-European Express, I only know from Kraftwerk and having seen models of the DB trainsets.
