Prototype: Class RCe 2/4 ”Roter Pfeil” / ”Red Arrow” electric fast powered rail car, 3rd class, as a museum unit maintained for extra runs by the Oensingen-Balsthal Railroad, Inc. (OeBB). Overhauled to reproduce the powered rail car’s external appearance in the mid-Fifties in an SBB crimson basic paint scheme. Powered rail car road number 607. The unit looks as it did in 2023.
