SBB-CFF-FFS RBDe 560

In 2003 six RBDe 560 (105, 127-128, 133-135) were converted to RBDe 561 (000-005) so that they could operate on the Wiesental section of the Basel S-Bahn (Basel - Zell im Wiesental, Germany). With the subsequent delivery of 10 RABe 521 (Stadler FLIRT) specifically for this network, these six RBDe 561 were returned in May 2006 to the Swiss side of the Basel S-Bahn and now operate again as RBDe 560. However, these trainsets remain recognizable because they still have certain German radio equipment installed.

At the beginning of 1997, only one year after delivery, six more RBDe 560 (136-141) were converted to operate on the French section of the Basel S-Bahn (between Basel and Mulhouse). These bi-current trainsets received the designation RBDe 562 (000-005), and are capable of operating on the 15 kV/16.7 Hz SBB standard as well as the 25 kV/50 Hz SNCF standard.

SOB variant in new livery

The Südostbahn (SOB) also ordered four two car NPZ sets (RBDe 566 + ABt), which were delivered out of the first production run in 1995 receiving fleet numbers RBDe 566 400-403. The SOB opted not to convert any intermediate cars for use with these trainsets. To provide first class accommodation the SOB control trailers have a first class compartment, thus the designation ABt, as opposed to SBB's second class only Bt. The motor cars are, except for the livery, identical to those of the SBB. The SOB has since converted several intermediate cars and operates the trainsets with them.

After the merger of the original SOB with the Bodensee-Toggenburg-Bahn (BT) to the new SOB, these four trainsets were repainted in the new livery of the SOB in 2003. They now operate throughout the SOB network as RBDe 566 077-080.

For services on the Seehas line (the area near Konstanz, Germany), the Mittelthurgaubahn (MThB) in 1993 took four NPZ trainsets off the SBB's production line. These 4 trainsets came from the first production series, and were delivered to the MThB in 1994 numbered as RBDe 566 631-634. These 4 trainsets would have been the ninth to twelfth for the SBB, which subsequently increased its total order by four.

These four MThB trainsets were also delivered with one new intermediate car each. Two additional driving trailers were used with older ABDe 536. Because they operate into Germany as well as within Switzerland, the vehicles were equipped with the Indusi train safety system and a wider pantograph shoe.

Upon the dissolution of the MThB, the trainsets went to the successor company Thurbo and were operated on the Seehas German section by Thurbo's German subsidiary EuroTHURBO and later SBB GmbH. In 2006, nine Stadler FLIRT (RABe 526 651-659) took over the Seehas service. Thurbo subsequently sold the four trainsets plus the two extra driving trailers to SBB. They worked as RBDe 561 171-174/AB 30-35 671–674/Bt 29-35 971–976 in the S-Bahn Luzern system, partly over BLS tracks, for some time and have now been withdrawn. One motor car and two driving trailers were sold, the rest was scrapped.

NPZ of the Montafonerbahn in Schruns

The Montafonerbahn, which is headquartered in Schruns, Austria, operates two two-piece NPZ sets. The first was built in 1990, following the SBB series 2100-2183, and the second in 1993, before the SBB second series.

The Chemin de fer Pont Brassus (PBr) has never possessed its own locomotives, but has always subcontracted operation to the SBB, which guarantees through service between Vallorbe–Le Pont (SBB) and the PBr route Le Pont-Le Brassus in the Vallée de Joux.

The "+2" in the first series production count are the two trainsets which were sourced in 1989 the line and went to the PBr. The locomotives originally received the designation RBDe 4/4 2184-2185. Only small labels referring to the PBr as the owner of these vehicles distinguished them, while the SBB remains responsible for their maintenance and operation. After the January 2001 merger of the PBr with the Chemin de fer Yverdon - Ste Croix (YSteC), which formed TRAVYS, the trainsets were repainted into that company's new livery and the motor coaches renumbered RBDe 568 384-385.
