Budapest Cog-wheel Railway
The Budapest Cog-wheel Railway, is a rack railway in the Buda part of the Hungarian capital city of Budapest. It connects a lower terminus at , two tram stops away from the Széll Kálmán tér transport interchange, with an upper terminus at . The line is integrated into the city's public transport system as tram line number 60, is in length, and was opened in 1874. The railway is operated by BKV, who also operate the city's tram and metro lines. It runs throughout the year between the hours of 0500 and 2300. As a  fully integrated part of Budapest's public transport system, standard tickets and passes can be used. The Városmajor terminus is adjacent to the Budapest tram stop of the same name, whilst the Széchenyihegy terminus is a walk from the similarly named terminus of the Budapest Children's Railway. History. Since 1868 a horse tramway ran on schedule from the Lánchíd to set in operation by the "Budai Közúti Vaspálya Társaság" (~ Public Railway Society of Buda). Nikolaus Riggenbach (the designer of the Vitznau-Rigi railway, Europe's first rack railway that opened in 1871) and a colleague, as the representatives  of the "Internationale Gesellschaft für Bergbahnen", applied for the construction of a rack railway uphill from to . The building permit was issued on 3 July 1873, and construction of the line began immediately, thus enabling the service to start up in the following year. The first introductory vehicle ran from 4 p.m. on 24 June 1874, and regular traffic began on the following day. The whole line was of standard gauge, built according to Riggenbach's cog-wheel system, and was operated by steam locomotives pushing coaches uphill and hauling them downhill. The single track railway was long with a  difference in elevation of . Successful operation of the cog-wheel railway raised the issue of extending the line. The plan was brought to fruition in 1890, when traffic started to , increasing the length of the line to . The municipal transportation company took over the railway in 1926. The new owners soon started to upgrade the line, by electrifying it using the same 550/600V DC system used by the city's trams, by adding new passing loops, replacing old trackage, and providing better schedules. New were built by SLM and Ganz, and the modernised operation started in 1929. From July 2 , 1929, the new electrically powered vehicles ran every 15 minutes. During and after World War II the line became very run down, and closure became a possibility. However this was averted, and in 1973 the line was completely rebuilt to celebrate the 100th anniversary of the merger of Buda, Pest and Óbuda into Budapest. The track was renewed using the Strub cog-wheel system, the line voltage was increased to 1,500V and new vehicles, built by SGP and BBC, introduced. The older trains last ran on 15 March 1973 and traffic using the new, and current, vehicles began on 20  August of the same year. Future developments. The Urban and Suburban Transit Association (VEKE) is advocating that the line be extended in both directions ("Normafa" and "Széll Kálmán tér").
