much of the operational and safeworking infrastructure remains in place in this section, including signalling equipment, level crossings, and easements. station platforms are also in place, but mostly without station buildings, for example at lang lang, koo-wee-rup, and tooradin. parts of the track have warped due to erosion, ground movement or the displacement of sleepers. this is especially evident near lang lang, tooradin, and north of koo-wee-rup. there are also questions about the integrity of some bridges and culverts along the route.
