Some background on the place: == Transport ==
Ferntree Gully has a railway station located on Station Street, near the shopping district, which was previously known as Lower Ferntree Gully, followed by Fern Tree Gully, having been changed to the latter on 29 February 1972. Build era is the best single predictor of cable type and board vintage. Day to day we are across Ferntree Gully and the streets either side of it: Boronia, Knoxfield, Lysterfield and Rowville. Same crew, same rates, same certificate at the end.
The run from Boronia to Ferntree Gully is about 2.7 kilometres south. That is a normal day for us, not a special trip. A second note on how the suburb came to be: The area became more accessible to visitors with the arrival of a railway line extension from Ringwood, completed in 1889.
It is also worth knowing that Officially opened on 17 October 1959 as the Mountain Gate Estate, it was marketed as the "town of a thousand homes" incorporating a modern car-oriented shopping centre and public parkland.
