TheRABe 514 is aclass of four-cardouble-deckerelectric multiple unit used by theSwiss Federal Railways (SBB) for theZurich S-Bahn. It is part of theSiemens Desiro Double Deck product family. The trains are also referred to asDTZ, which stands for the German wordDoppelstocktriebzug (lit. 'double deckermultiple unit').
On 23 February 2003 the Swiss Federal Railways' board of directors decided to give the 447 millionCHF contract for building 35 double decker trains toSiemens Transportation Systems. This decision came as a surprise since Siemens had never built double-deckerEMUs before, except for an experimental train built in a consortium with DWA Görlitz (nowBombardier Transportation) that never entered into service. To fulfill the domestic content requirement in the contract, Siemens reached an agreement withStadler Rail to perform some of the assembling and the commissioning in their factory inAltenrhein, Switzerland.[2]
The trains were originally intended to enter service in December 2005, but the date could not be kept.[3] Nevertheless, the first trainset was presented to the public on 2 December 2005 atZürich Hauptbahnhof. Until May of the next year, the RABe 514 were thoroughly tested and then entered into regular passenger service on theS14 line.[2]
In March 2006, the Swiss Federal Railways exercised their purchase option for another 25 units.[4] Because of the delayed delivery of the first trainsets, Siemens agreed to build an additional train instead of paying a penalty.[3] Delivery of all 61 trains was completed in July 2009.[5]
The DTZ trains are the second generation double decker trains used on the Zurich S-Bahn. Compared to theRe 450-hauled bilevel coaches, the first generation trainsets known as DPZ, the RABe 514 feature a low-level entrance for level boarding, air conditioning andvacuum toilets (in a washroom suitable for the disabled). The third generation trains of the Zurich S-Bahn areRABe 511 EMUs of Stadler Rail.
The four-car DTZ multiple unit consists of two powered end cars with two unpowered cars between them. Bothbogies in an end car are driven byinduction motors with a power output of 400 kW (536 hp) peraxle providing a total of 3,200 kW (4,291 hp) for the trainset. Since there was not enough space for a 15 kV power line through the train, both end cars draw their power from a separatepantograph.[1]
An automaticcoupling system allows for up to four trainset to be connected together for additional capacity during peak-hours; however, in practice the maximum is three connected trains due to the limited platform lengths of 300 m (984 ft 3 in) at the train stations.
The double decker trains provide 74 seats infirst class, 304 seats in second class as well room for about 600 people standing. The first class seats are equipped with normal 230 V power outlets for charging notebooks and other devices.[1]
The RABe 514 are used on lines previously served byDPZ trainsets. The thereby freed up DPZ were then used to replace the old single deck trainsRABDe 510 andRBe 540 from the 1960s.
The first line served by the new Siemens trains was theS14 (Hinwil–Zürich Hauptbahnhof). Starting in December 2006 theS7 (Rapperswil–Zürich–Winterthur) line was also equipped with the DTZ. However, all newly delivered trains were first put on the S14 line because that line is better suited for testing due to its short length and lower importance than other lines. After the S7 line got all of its required 15 trainsets, the next trains were intended to go to theS5 line, but that plan was abandoned in favor of theS15 (Affoltern am Albis-Zürich-Rapperswil). With delivery of the second batch, theS8 (Pfäffikon-Zürich-Winterthur) line was equipped as well. The formerS16 (Meilen-Zürich-Thayngen) also used DTZ trains.
The use of DTZ was changed after a major overhaul of the Zurich S-Bahn network between 2014 and 2018.[6] As of the December 2022 timetable change,[update] the RABe 514 is primarily used on fiveZürich S-Bahn routes:S2,S6,S8,S16 andS24.[7]
The original plan to couple first and second generation trains together to provide level-boarding on more lines could not be implemented due to software problems when connecting the two train generations.

It is common practice in Switzerland to name electric multiple units (e.g.RABe 501,RABDe 500) and locomotives (e.g.Ae 6/6,Re 6/6,Re 450,Re 460). Similarly, some RABe 514 trainsets were named, mostly aftercommunes (or former communes), in which case the commune'scoat of arms is also indicated at both ends of the trainset. The table below lists all named units:[8]
| EMU № | Name |
|---|---|
| 514 006 | Hans Künzi[9] |
| 514 007 |  Bülach |
| 514 012 |  Russikon |
| 514 016 |  Schaffhausen |
| 514 017 |  Wetzikon |
| 514 022 |  Frauenfeld Weinfelden |

| 514 052 |  Wipkingen |

| 514 060 |  Oerlikon |
In addition, RABe 514 015 currently has theZVV special livery.
On 20 February 2015, unit № 514 046-2 was involved ina collision with anInterRegio express train hauled byClass 460electric locomotive (№ 460 087) atRafz.[10][11]
