Railway Technology Museum, Railway museum in Paranapiacaba, Brazil.

The Railway Technology Museum occupies the 1867 workshop buildings of the São Paulo Railway in Paranapiacaba, at the top of the Serra do Mar. Its halls hold the cable-hauled funicular system's machinery, including the endless rope of the 1900 Serra Nova line, plus locomotives and tools. A restored section of the fifth-to-fourth-patamar track, operated from 1987 to 1991, shows how cars were hauled up the slope.

The museum occupies workshops begun in 1867 by the São Paulo Railway, the company that built the Santos–Jundiaí line. These sheds served the funicular systems: the first, Serra Velha, opened in 1867 and closed in 1974; the second, Serra Nova, used endless rope from 1900 and ended commercial operation in 1983. The railway was taken over by the Brazilian government in 1946. Since 2005 the museum has been run by ABPF.

The museum is run by the ABPF, the Brazilian Railway Preservation Association, which took over the site in 2005 when the railway preservation body PRESERFE was wound up. Volunteers keep the collection and, from 2008, brought a steam train ride back to Paranapiacaba. The name visitors see on the buildings, Museu Tecnológico Ferroviário do Funicular, ties the collection to the cable-hauled funicular system it documents.

The museum is easy to navigate with several connected exhibition halls within the station district. The site is compact and manageable, allowing visitors to see all areas in a single visit while remaining well-oriented between buildings.

The museum preserves original maintenance equipment from the Serra do Mar mountain railway system, which transported trains up steep slopes using an innovative cable mechanism. This clever method allowed heavy cargo to move uphill without straining steam locomotives.
