The SIGNAL building was formerly known as Signal Box “A”, the last remaining building in the Flinders Street Railway Station Complex that pre-dates the major redevelopment of the station between 1900 and 1910. Signal Box “A” is the only existing evidence of the operation of the manual switching of track points to the introduction of the current electronic system. The heritage building has now emerged into a modern youthful presence, an artistic hive attracting young people from all over Melbourne to partake in SIGNAL’s multi-artform program offerings.
