- 1959 September, P. Ransome-Wallis, “The British Railways Class "9" 2-10-0s”, in Trains Illustrated, page 419:
  The balancing of the engine is unusual, with the rotating masses fully balanced and 40 per cent of the reciprocating masses statically balanced by lead weights in the coupled wheels; the reciprocrating balance weights are in the same phase on both sides of the engine. This system saves balance weight and reduces the wheel hammer-blow.
