Porterbrook Class 170 Turbostar on the Derby to Matlock local. These units were built as demonstrator and speculative hire vehicles. The Derby - Matlock route has often been a running in turn for new units and locomotives, during the Modernisation Programme locomotives built at Derby works were put on the Derby - Manchester turn, after this route was truncated at Matlock so was the test route, being close to the engineering works and also their builder this route was ideal. Obviously old habits die hard! Copyright belongs to Andy Ducker. Email address ecml@yahoo.co.uk. All pictures take by me on a Kodak DC260 Digital Camera, and slightly processed using Paint Shop Pro 5
