Treffry opened the track from Newquay Harbour to St Dennis, with a branch to the important East Wheal Rose lead mine. In 1873 these were to form part of the Cornwall Minerals Railway. Later, the line was extended to Par, following some of the course of Treffry’s original tramway but passing underneath the Treffry viaduct, through the Luxulyan valley. This became the current Newquay branchline, part of the Great Western network, in 1896.
