A comment often made about the Station Road Steam Feldbahn or Stafford engines is that the globe valves controlling the steam to the injectors, blower, and vacuum brakes look quite large and out of scale.   The reason for using them is that they work well and are easily available, as well as being sensibly priced.  These are all good reasons for using them but there is an alternative. When I owned my Stafford I refitted it with the smaller globe valves made by R A Barker as shown in this photo, and in June 2016 I fitted identical valves to my Feldbahn.  You can read all about this modification in the Functional Modifications pages of the Stafford section of this website (or just click here.to jump to the relevant page).
