All Aboard

In 1911 a porter, who was moving a mail bag across a railway line with other luggage on a truck, did not notice that an express goods train was due to pass through the station until the last moment! He then hurried forward to escape it, and in doing so the mail-bag was jolted from the truck on to the line. The train went over it and mutilated several of the letters. We need your help! Scan visual markers, placed around Rushden, with your camera to recover the letters and reveal pieces of Rushden's history.
