RJ seems to have at least two configurations, with possibly a third entering service. Older version is the compartments while the newer/2nd version is the 6-seat open version at the front (or rear) of the train.
Been on Ceske Drahy version (6 seats with 2 pairs facing each other) and am booked for a l-o-n-g trip on an OeBB train later this year which is currently scheduled to be the second version.
