    • 1960 April, “Talking of Trains: Safety with 25kV a.c.”, in Trains Illustrated, page 203:
      The overhead line was energised at 25,000 volts and the height of the contact wire was reduced to 11 in. above the chimney, then to 5 and finally to 2 in.; at this last, short distance the flashover occurred, but all the men were perfectly safe because the current went direct to earth through the locomotive.
