Bemo 3298 117 RhB Bt 528 07 AGZ control car
Universal control car
Together with the AGZ control car Ait 578 01-06, the RhB procured eight control cars Bt 528 01-08 with a single-color, neuro-red paint finish with changed seating. These are now used, among other things, for the extension of the Landquart - Davos - Filisur trains with "Allegra" dual system trains, with reinforcement cars being carried at the end of the train in some cases.
