A ghost station is a disused train station through which revenue-service passenger trains pass but at which they do not stop. The term is also sometimes used for any unused underground station or any unused station, whether or not trains pass through them. In Germany, a station that has been built in the course of constructing something else as a so-called "Bauvorleistung" is referred to as a "ghost station", despite the different purpose and origin of the terms. Some English-language publications also refer to "pre-built" stations or parts thereof that have yet to see service as "ghost stations".

The Berlin U-Bahn originated in 1880 with Werner Siemens' idea to build an urban railway in Berlin. During the nine years after the German Empire was founded, the city's population grew by over one-third and traffic problems increased. In 1896, Siemens & Halske began to construct the first stretch of overhead railway. On 1 April 1897, the company began construction of an electric underground railway. The Berliner Verkehrs Aktiengesellschaft (BVG) was formed in 1928, and took over further construction and operation of the network. In 1938, the company was renamed Berlin Transport Company; the original acronym, however, remained. Since 1994, the BVG has been a public company.
