 Many railway administrations converted their steam engines to Giesl ejectors, including the ÖBB, ČSD and Deutsche Reichsbahn (DR) in East Germany, as well as railway companies in Africa, China and Japan.The licence fees were not paid in every case, it being said that often they almost cancelled out the saving in coal.In the DR it was assessed that the Giesl ejectors would pay for themselves within a year, as a result of which they converted over 500 locomotives; primarily the Classes 38.10, 50, 52 and 65.10.
