Mundaring Weir Branch Railway

The Mundaring Weir Branch Railway was constructed from Mundaring, Western Australia to the site of the Mundaring Weir, and opened on 1 June 1898.

Overview
One of the rail lines constructed by the Public Works Department in the early 20th century, the line was specifically built for the construction of the weir, and incorporated a zig zag.

The line taken over by the Western Australian Government Railways some years after its construction.

The branch was popular for picnics and excursions to the weir between the 1920s and 1940s.

Difficulties
Due to the steep grades down to Mundaring Weir, a limited range of locomotives were permitted to be run on the line.

In the 1940s the declining availability of Msa Garratt steam locomotives affected the number excursion trains that could run to the weir. This was a particular problem during times when the weir overflowed, because the Msa Garratt seemed to be the only engine in service capable of negotiating the steep gradients.

Due to lack of activity on the line in the early 1950s it was closed on 14 November 1952. A bill to officially close the line passed state parliament in December 1952.

Services on the connecting line, Mundaring Branch Railway, ceased traffic on 23 January 1954. The line was closed by parliament in 1966.

Different proposals since 1966 to resurrect the railway line as a tourist attraction have not materialised.

Stopping places
The branch commenced to the east of the Mundaring Railway Station yard.
