The original section remains open as part of the London to Penzance main line, the Truro to Falmouth line being operated as a branch. It stands 37m high with 12 18m-wide arches and was built between 1904 and 1907 following the construction of the Brunel Bridge.Penponds Viaduct was built by the West Cornwall Railway in 1857 to replace an inclined plane that had been built 20 years before by the Hayle Railway. This design was chosen by Isambard Kingdom Brunel in order to reduce the cost of their construction, but at the expense of high maintenance costs. The Cornwall Railway viaducts were mostly built on stone piers but with spans of timber fans. The extension to Falmouth was completed in 1863. Alongside it, fourteen of the original Brunel piers are still standing. Of these forty two were crossed by timber viaducts of various types. The section from Plymouth to Truro opened in 1859 when the Saltash Bridge was opened. It became a popular route from the Caradon mines following the discovery of copper ore at South Caradon Mine in 1836.
Penponds is situated close to Camborne. OpenStreetMap with Locations from Wikipedia. Penponds is situated close to Camborne.As many of the area’s mines were relatively close to navigable water, canals were generally a less practical option for transportation. This design was chosen by Isambard Kingdom Brunel in order to reduce the cost of their construction, but at the expense of high maintenance costs.

This design was chosen by Isambard Kingdom Brunel in order to reduce the cost of their construction, but at the expense of high maintenance costs. As many of the area’s mines were relatively close to navigable water, canals were generally a less practical option for transportation. The solution was this 198m long, 30m high viaduct – the most advanced engineering project in the western peninsula at the time.Calstock Viaduct was built to carry the East Cornwall Mineral Railway at high level over the River Tamar. The remainder were the River Tamar at Saltash crossed on the Royal Albert Bridge, the River Fowey at Lostwithiel crossed by a low three-span viaduct (two spans being timber, the central one iron), and the river and canal at Par crossed on a five-arch low stone viaduct.Replacement of the viaducts started in 1875 but led to a dispute between the Cornwall Railway and the Great Western Railway which leased the line.

This connected by inclined plane to Lanescot Mine and Fowey Consols and was part of the development of the Luxulyan Valley initiated by Treffry. My Internet friend, Laurent Truillet, noticed the pillars in front of the viaduct and asked if the 'previous bridge was a wooden bridge'. It was the most advanced engineering project in the western peninsula at the time.For the tramroad which was later built across the valley, a high-level crossing of the river was required.
Yesterday my post was VIADUCT AND TRAINS, CORNWALL and I'd like to continue this theme today. It was leased by the South Devon, Bristol & Exeter and Great Western Railways and in 1889, the Cornwall amalgamated with its three associate companies.The Cornwall Railway viaducts were mostly built on stone piers but with spans of timber fans. The lease precluded the conversion of the broad gauge line to standard gauge, and the Cornwall Railway refused to pay for the widening of the viaducts during rebuilding to accommodate a double line of standard gauge tracks (it had been built as a single-track line).Following the amalgamation of the two companies on 1 July 1889, all the remaining viaducts were replaced, those between Saltash and St Germans being replaced by a deviation line, the remainder being either rebuilt in situ or having a replacement viaduct built immediately alongside. Penponds Viaduct was built by the West Cornwall Railway in 1857 to replace an inclined plane that had been built 20 years before by the Hayle Railway. Above is another photo of the Trenance Viaduct, but from a different angle to yesterday's picture.
