SBB-CFF-FFS RBDe 560
The RBDe 560 (in the old naming style, the RBDe 4/4) and its derivatives provide motive power for S-Bahn, suburban, and regional traffic on the Swiss Federal Railways (SBB) network. The derivative versions belong to the SBB as well as various private railroads. The locomotive and its matching Bt model Steuerwagen (translation: control car/cab car/driving trailer) form compositions generally known as the Neuer Pendelzug (New Commuter Train), which is the source of the acronym NPZ. An NPZ trainset usually includes one or more intermediate cars.
