On 23 February 2003 the Swiss Federal Railways' board of directors decided to give the 447 million CHF contract for building 35 double decker trains to Siemens Transportation Systems. This decision came as a surprise since Siemens had never built double-decker EMUs before, except for an experimental train built in a consortium with DWA Görlitz (now Bombardier Transportation) that never entered into service. To fulfill the domestic content requirement in the contract, Siemens reached an agreement with Stadler Rail to perform some of the assembling and the commissioning in their factory in Altenrhein, Switzerland.{{cite web |url=http://www.elektrolok.de/Kurzprofile/kp_RABe514.htm |title=Der Doppelstocktriebzug DTZ RABe 514 der S-Bahn Zürich |accessdate=28 November 2009 |author=Ludwig Reyer |publisher=Elektrolok.de |language=German |archive-date=3 March 2016 |archive-url=https://web.archive.org/web/20160303194254/http://www.elektrolok.de/Kurzprofile/kp_RABe514.htm |url-status=dead }}

The trains were originally intended to enter service in December 2005, but the date could not be kept.{{cite news |title=Erste S-Bahn Komposition verspätet abgeliefert: SBB erhalten von Siemens gratis einen Doppelstockzug |author=Roger Keller |newspaper=Tagesanzeiger |date=22 October 2008}} Nevertheless, the first trainset was presented to the public on 2 December 2005 at Zürich Hauptbahnhof. Until May of the next year, the RABe 514 were thoroughly tested and then entered into regular passenger service on the S14 line.

In March 2006, the Swiss Federal Railways exercised their purchase option for another 25 units.{{cite web |url=http://www.nzz.ch/2006/03/06/zh/newzzEKGMJOT6-12.html |title= Weitere neue Triebzüge für die Zürcher S-Bahn | accessdate=28 November 2009 |date=6 March 2006 |publisher=NZZ Online |language=German}} Because of the delayed delivery of the first trainsets, Siemens agreed to build an additional train instead of paying a penalty. Delivery of all 61 trains was completed in July 2009.{{cite press release |title=Die Doppelstöcker-Flotte der S-Bahn ist komplett |publisher=Zürcher Verkehrsverbund |date=7 July 2009 |url=http://www.zvv.ch/de/medien/medienmitteilungen/archiv-2009.html#07072009 |language=German |accessdate=29 November 2009 }}

The DTZ trains are the second generation double decker trains used on the Zurich S-Bahn. Compared to the Re 450-hauled bilevel coaches, the first generation trainsets known as DPZ, the RABe 514 feature a low-level entrance for level boarding, air conditioning and vacuum toilets (in a washroom suitable for the disabled). The third generation trains of the Zurich S-Bahn are RABe 511 EMUs of Stadler Rail.

The four-car DTZ multiple unit consists of two powered end cars with two unpowered cars between them. Both bogies in an end car are driven by induction motors with a power output of {{Cvt|400|kW|4=0}} per axle providing a total of {{Cvt|3200|kW|4=0}} 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 separate pantograph.

An automatic coupling 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 {{Cvt|300|m|ftin}} at the train stations.

The double decker trains provide 74 seats in first 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.

The RABe 514 are used on lines previously served by DPZ trainsets. The thereby freed up DPZ were then used to replace the old single deck trains RABDe 510 and RBe 540 from the 1960s.

The first line served by the new Siemens trains was the S14 (Hinwil–Zürich Hauptbahnhof). Starting in December 2006 the S7 (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 the S5 line, but that plan was abandoned in favor of the S15 (Affoltern am Albis-Zürich-Rapperswil). With delivery of the second batch, the S8 (Pfäffikon-Zürich-Winterthur) line was equipped as well. The former S16 (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.{{cite web |url=https://www.zvv.ch/en/about-us/projects/in-operation/4th-partial-expansions.html |title=4th partial expansion |publisher=ZVV |access-date=2025-01-19}} {{As of|alt=As of the December 2022 timetable change|2022|12|post=,}} the RABe 514 is primarily used on five Zürich S-Bahn routes: S2, S6, S8, S16 and S24.{{Cite web |title=Annual formation |url=https://data.sbb.ch/explore/dataset/jahresformation/table/?refine.beginnfahrplanperiode=Fpl-2023&refine.block_bezeichnung=RABe514&refine.zugart=S |access-date=2023-01-08 |website=data.sbb.ch |language=en}}

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 after communes (or former communes), in which case the commune's coat of arms is also indicated at both ends of the trainset. The table below lists all named units:{{cite web |url=http://www.juergs.ch/eisenbahn/triebzuege/rabe-514/ |title=SBB RABe 514 “DTZ” |publisher=juergs.ch |access-date=2025-01-19 |language=de}}

In addition, RABe 514 015 currently has the ZVV special livery.

On 20 February 2015, unit № 514 046-2 was involved in a collision with an InterRegio express train hauled by Class 460 electric locomotive (№ 460 087) at {{rws|Rafz}}.{{cite news |url=https://www.bbc.com/news/world-europe-31547979 |title=Switzerland Zurich: Injuries as trains collide in Rafz |work=BBC News |date=20 February 2015 |accessdate=20 February 2015}}{{cite news |first=Fabian |last=Baumgartner |url=http://www.nzz.ch/zuerich/unfall-zug-rafz-1.18487271 |title=Zugunglück in Rafz: Lokführer waren in Ausbildung |trans-title=Accident in Rafz: Drivers were in training |newspaper=Neue Zürcher Zeitung |date=20 February 2015 |accessdate=20 February 2015 |language=German}}
