The Re 450 is a push-pull electric locomotive of Swiss Federal Railways (SBB CFF FFS), which combined with passenger coaches is only used for commuter rail services of Zurich S-Bahn in the metropolitan area of Zurich. Under the old Swiss class system, they would have been known as Re 4/4^V.

Each Re 450 is used in formations of three double-deck passenger carriages, the last of which has a driving cab to allow push-pull working. At peak-hour times, trainsets may be coupled together to form a train consisting of three locomotives and nine passenger vehicles. Most Zurich S-Bahn lines use this stock and it is the most common on the network.^[2] The trainsets are also known as DPZ, short for Doppelstock-Pendelzug (lit. 'double-decker commuter train'),^[3] which was 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.

In 2008, two Re 450 trainsets, with locomotives Re 450 067 and Re 450 070, were sold to Sihltal Zürich Uetliberg Bahn (SZU), where they are now designated as Re 456 551-1 and Re 456 552-9, respectively.^[4]

All Re 450-hauled trainsets received a mid-life refurbishment at the SBB CFF FFS workshops in Yverdon-les-Bains between 2011 and 2018 (now named DPZplus). The livery was changed: the formerly yellow doors are now painted red on the coaches and dark blue on the locomotives, and the front now shows the SBB logo instead of only the vehicle number. Each trainset now includes one low-loader wagon for easier access.

Numbering and naming

All 115 Re 450 locomotives are numbered (000–114) and each is named after a commune, mostly of the canton of Zurich. The numbers are indicated at the front and sides of the locomotive, the names (with the commune's coat of arms) are displayed on the side of the engine.^[5]^[6]

The following is a list of Re 450 locomotives with their respective number and name.
