Remnants of closed railway lines diminish and disappear as a result of natural and human activity, but some relics from the Fairlie Branch's operating days still exist, most notably the 2.5 km of restored trackage still in use by the Pleasant Point Museum and Railway. At Washdyke, the first few hundred metres of the branch were retained as a backshunt and to provide access to an industrial siding, and the track currently remains in place. For much of the line's length from Timaru to Fairlie, the formation can be seen making its way through the rolling countryside, and abutments and piles still stand at the site of some bridges.
