SBB CFF FFS EW II coach A 50 85 18-33 621-1 in a RegioExpress to Schaffhausen, stopping at track 21 (which is usually reserved for S-Bahn trains). The interior of this classic inland coach was only subtly modified, and it is still popular among first class passengers - certainly better than the EW II converted to 2+2 seating for local services such as NPZ units.
