Wheel-Tapper at work
A portrait of a wheel-tapper at work, checking the wheels of a bogie carriage at Leicester Central Station, circa 1910. The job of a wheel-tapper was to test wheels for cracks or fractures. Using a wheel-tappers hammer (seen in the photograph), the wheel-tapper would strike each wheel, and could tell by the sound it made whether the wheel was damaged. Note the Great Central Railway crest on the carriage side above the wheel-tapper's head.
