The famous viaduct at Knaresborough in North Yorkshire, built in 1851 to carry the line from York to Harrogate. At first glance you might think the train is a pair of class 153s, but it’s not. It’s one of the seven class 155s originally sponsored by West Yorkshire PTE, which were never split and converted into single-car units.
Although it now carries only local traffic, Knaresborough sees a surprising variety of trains; in the space of a few hours I saw class 142 and 143 Pacers, and class 150, 153 and 155 Sprinters.
