    • 1961 Novenber, “Talking of Trains: The subsidence problem”, in Trains Illustrated, page 651:
      Everyone knows that a main line running through a coalfield is prone to speed restrictions because of land subsidence. [...] The rate of subsidence may vary from less than an inch a month in the case of a deep seam of coal, to as rapid a decline as 16in a month above a shallow seam. The effect of subsidence on permanent way and civil engineering structures needs no emphasis.
