This wheeltapper is testing the wheels of a carriage in the British Railways' Scottish Region. Wheeltappers could detect cracks and flaws in the wheels and anxles by the distinctive ringing note they made when struck with a long handled hammer. Their job also included inspecting couplings, connections and brake blocks. Wheeltappers were replaced in the 1970s following the introduction of ultrasonic testing and lineside equipment which could detect overheated axle boxes. Photograph by Pat Ransome- Wallis.
