In Mount Helena the Railway Reserves Heritage Trail continues as a line 22.5 km (14.0 mi) in length, called Eastern Extension, onto Wooroloo.
The Avon Valley route taken by the new Standard Gauge line, was the third and final attempt to take the railway system out of the metropolitan area across the Darling Scarp.
Interesting exceptions to the removal of railway operations assets are the stationmaster's houses in Mundaring and Glen Forrest - these have been preserved and maintained.
Considerable funds have been given to the Mundaring shire to maintain the reserve for use by walkers, cyclists and horse riders (hence the Bridle Trail name recurring).
Sections of the reserve have important ecological features that contain examples of a range of conditions found in the region.
