History

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

. 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. 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.


Specifications

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

Interior

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.


Service

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. the RABe 514 is primarily used on five Zürich S-Bahn routes: S2, S6, S8, S16 and S24. 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.


Naming and special livery

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
