First Great Western HSTs were diverted away from the Reading area over the Christmas & New Year periods in 2010/11. This was to allow major engineering works to take place at Reading station. One of the routes to see the diverted trains was the former Southern route from Waterloo. On 1 January 2011 several trains from the west terminated at Basingstoke, but one that did complete its journey was the 1O40 06:50 Penzance to Waterloo, seen here deep in third rail territory at Potbridge, headed by 43174.
