Hi, I'm really glad you haven't scrolled past this cache listing, so lets go for a quick walk across the viaduct and learn a bit of it's history, careful while up the top as the winds up here can get a bit breezy, there is nothing to find at the posted co-ordinates, you'll only end up breaking your finger nails if you search here, instead work out this simple puzzle and you'll soon have the magic numbers you need, anyhow, on with the history lesson....
The Leeds and York Railway was promoted in the 1840s, during the Railway Mania; the line formed an alternative route from Leeds to York, starting in Wellington Street (Leeds), passing Seacroft, Thorner, Clifford Moor, and crossing the River Wharfe near Thorparch continued via Walton, Syningthwaite, Bilton, Hutton Wandesley, Rufforth and Acomb to York.
The line was 6.5 miles (10.5 km) shorter than the existing route between the two cities (York and North Midland and Leeds and Selby lines). An associated scheme the York, Hull and East and West Yorkshire Junction Railway was also proposed, connection towns in the East Riding of Yorkshire; together they represented a potential strong competitor to George Hudson's railway network in Yorkshire.
The Tadcaster Viaduct (also known as the Virgin Viaduct, or Virgin Bridge) was constructed as part of the northern section of the Leeds-York Line.
The viaduct was constructed of 11 arches, 7 west of the river, 2 east of the river, and 2 wider arches across the River Wharfe; made of magnesian limestone with millstone grit arch voussoirs. Earthworks were constructed for a triangle junction connection to the Harrogate-Church Fenton line immediately northwest of Tadcaster railway station; the viaduct crossed the river upstream and north of the town.
From 1882 or '83 to 1955 there was a siding across the viaduct which was used to supply corn and later coal to Ingleby's Mill on the east bank of the river. After 1901 the Mill was converted to a power station for the Tadcaster Electricity Company. The siding, known as the Ingleby's Mill branch closed in 1959. In 1980 the viaduct was acquired by the town council from British Rail. The structure was listed in 1985.
Ok, worked it out? off you go and find the cache then....
