In 1931, the Railway Department agreed to supply electricity to the Blue Mountains Shire Council. Power lines were constructed between Blackheath and Lawson, accompanied by a maintenance track. The authorities then decided to promote the maintenance track as a walking trail; it became known as Bruce's Walk, after the surveyor who planned it. The track later became neglected and forgotten, until it was rediscovered and improved by bushwalkers in the 1980s. It can now be followed from Medlow Bath to the north side of Lawson, although it is not shown on the relevant topographic map.
