The Bm 4/4 is a class of heavy diesel shunting locomotives built for Swiss Federal Railways. 46 examples were built between 1960 and 1970, numbered 18401 to 18446, Starting in 2006, the class was slowly being replaced by new Vossloh-built locomotives. The last SBB example was withdrawn in 2024 but a few are in use with private operators

Swiss Federal Railways is the national railway company of Switzerland.
An articulated locomotive is a steam locomotive with one or more engine units that can move independently of the main frame. Articulation allows the operation of locomotives that would otherwise be too large to negotiate a railroad's curves, whether mainlines or special lines with extreme curvature such as logging, industrial, or mountain railways.
A Bo-Bo-Bo or Bo′Bo′Bo′ is a locomotive with three independent two-axle bogies with all axles powered by separate traction motors. In the AAR system, this is simplified to B-B-B due to the system only taking powered axles into consideration, not traction axles.
Crocodile electric locomotives are so called because they have long "noses" at each end, reminiscent of the snout of a crocodile. These contain the motors and drive axles, and are connected by an articulated center section. The center section usually contains the crew compartments, pantographs and transformer.
Alstom Traxx is a modular product platform of mainline diesel-electric and electric locomotives. It was produced originally by Bombardier Transportation and later Alstom, and was built in both freight and passenger variants. The first version was a dual-voltage AC locomotive built for German railways from the year 2000. Later types included DC versions, as well as quadruple-voltage machines, able to operate on all four electrification schemes commonly used in Europe. The family was expanded in 2006 to include diesel-powered versions. Elements common to all variants include steel bodyshells, two bogies with two powered axles each, three-phase asynchronous induction motors, cooling exhausts on the roof edges, and wheel disc brakes.
The Buchli drive is a transmission system used in electric locomotives. It was named after its inventor, Swiss engineer Jakob Buchli. The drive is a fully spring-loaded drive, in which each floating axle has an individual motor, that is placed in the spring mounted locomotive frame. The weight of the driving motors is completely disconnected from the driving wheels, which are exposed to movement of the rails.
For more than a century, the Swiss locomotive, multiple unit, motor coach and railcar classification system, in either its original or updated forms, has been used to name and classify the rolling stock operated on the railways of Switzerland. It started out as a uniform system for the classification and naming of all rolling stock, powered and unpowered, but had been replaced and amended by the UIC classification of goods wagons.
The SBB Em 3/3 is a diesel shunting locomotive of the Swiss Federal Railways (SBB). They were built between 1959 and 1963, with a total of 41 units being manufactured by the Swiss Locomotive and Machine Works. They were designed to perform shunting duties for the SBB and were assigned running numbers 18801 to 18841.
The DBAG Class 145 and DBAG Class 146 are Bo′Bo′ mainline electric locomotives built by Adtranz primarily for the Deutsche Bahn at the end of the 1990s. The Class 145 is the freight version for DB Cargo; the Class 146 is the passenger version for DB Regio. Additional freight machines were built for the former Swiss railway Mittelthurgaubahn as well as for various private operators and leasing companies.
The Swiss Class A 3/5 locomotives were built between 1902 and 1922 for the Jura–Simplon Railway, and the Gotthard Railway. These railways were absorbed into Swiss Federal Railways in 1903. In total 111 4-6-0 locomotives of this type were built by Schweizerische Lokomotiv- und Maschinenfabrik in Winterthur, Switzerland.
The Swiss Class B 3/4 locomotives were built between 1905 and 1916 for the Swiss Federal Railways. In total 69 2-6-0 locomotives of this type were built, and numbered 1301–1369.
The Swiss Class De 6/6 electric locomotives were built in 1926 for the Swiss Federal Railways. Ordered for the Seetalbahn line, which runs between Lenzburg and Emmenbrücke, they were Known as Seetal Crocodiles. In total 3 locomotives of this type were built, and numbered 15301–15303. As built they were capable of operating under dual voltage - the 5.5 kV, 25 Hz AC system in use on the Seetal line, and the national 15 kV 16+2⁄3 Hz AC system. The former system was removed from these locomotives in 1930, when the line was modernised to SBB national standards.
The Ee 922 is a class of 21 electric shunting locomotives built since 2009 by Stadler Rail for Swiss Federal Railways.
The C 5/6 were a class of steam locomotives in use for the Swiss Federal Railways. 28 of them were built between 1913 and 1917; all had been withdrawn by 1968. Four have been preserved, one of them in working order. The class was designed for use on the steep inclines of the Gotthard route, and was considered extremely efficient, earning the nickname Elephant. Its design was based on the successful C 4/5 locomotive, and the result is the largest steam locomotive operated by the Swiss Federal Railways. Within a few years of introduction, however, they began to be replaced by new electric locomotives.
The Re 450 is a push-pull electric locomotive passenger coach type which is used by Swiss Federal Railways on S-Bahn services in Zürich. They are also known as DPZ, short for double-decker push-pull train, and is the first double decker train type operated by SBB-CFF-FFS, following successful trials of a French VO 2N bilevel train borrowed from SNCF in the early-1980s.
The Am 6/6, later known as Am 861, is a class of diesel shunting locomotive which were built for the Swiss Federal Railways (SBB) and were intended for use as heavy hump shunters at the Limmattal classification yard.
The MaK G 1204 BB is a four axle B'B' diesel-hydraulic locomotive with and off centre cab design built by MaK in Kiel, Germany. Eighteen of these light freight and shunting locomotives were built which were used mostly on German industrial railways, two units have worked for the Swiss Federal Railways and received the class designation Am 842.
The Vossloh G1700 BB is a four axle B′B′ medium power diesel-hydraulic locomotive manufactured by Vossloh Locomotives GmbH. in Kiel.
The SBB Ae 8/14 is a class of electric locomotives built for Swiss Federal Railways to be used on the Gotthard railway. Only three prototype engines were built between 1931 and 1938, each of them in a different design.
The FS Class E.360 were electric locomotives of the Italian State Railways (FS), using three-phase alternating current, built for the operation of the Valtellina line. They were ordered by Rete Adriatica and were originally numbered RA 361–363. Italian railways were nationalized in 1905 and they then became FS E.361-363 They were leased to Swiss Federal Railways (SBB) in 1906 and returned to Italy in 1907.
