Description

This is a disused double track viaduct west of the former Cargill station and east of the former Ballathie station. It crosses the River Tay. It is a substantial five span truss viaduct.

It was a originally a laminated timber viaduct with stone piers designed by engineers Joseph Locke and John Errington working for the Scottish Midland Junction Railway, one of a chain of mainlines between Carlisle and Aberdeen.

The stone piers were re-used when the bridges of the Strathmore Main Line were replaced between the 1880s and 1890s (following the Caledonian Railway's review of its own structures after the Tay Bridge [1st] Disaster). Replacing the aging timber structures allowed speed restrictions to be lifted.

The timber was first replaced with five cast iron segmental arches in the 1880s (pre 1887).

A temporary 'Cargill Viaduct' signal box was setup during works on the bridge in April 1898.

The cast iron structure was replaced between 1918 and 1920 and a temporary 'Ballathie Viaduct' signal box was set up at the west end, north side, during further the works.

Replacement of the viaducts allowed the Strathmore Main Line to become a high speed line. When the three hour Glasgow - Aberdeen expresses ran in the 1960s line speeds of around 80mph (and over) were achieved at Cargill and Ballathie.

The line closed to passengers in 1967 and was singled, the former westbound line from Stanley Junction to Forfar [2nd] remaining in use for goods with a 30mph speed restriction. It closed in 1982 with track lifting the following year.

This structure was, at 540 ft long (50 ft over the river), the largest on the Strathmore route. Access is not possible with heavy fencing blocking access at both ends, house building at the west end and an enclosure at the east end.

The viaduct was also known as Ballathie Viaduct.
