This is a multifunction site:-

  DEErivatives gives details of live steam locos based around the G1MRA DEE mechanism. These are available mainly for Gauge 1.

  Orion Models gives details of GWR locos for Gauges 1 & 3
        and drawings for them available in any scale

  CAD/CAM consultancy offers advice and small-scale production facilities - to be added later.

  HobbyCNC, NG Railway drawings, and GWR are forums for useful information - please feel free to contribute to these by pressing the Contact Us button - all contributions will be attributed to the author.

  HobbyCNC provides advice on using small lathes and mills - some techniques may be applicable to manual as well as CNC machines

  NG Railway drawings provides an index (almost certainly incomplete) to Narrow Gauge Railway drawings that have been published over the last 50 years

  GWR is a forum for information on Great Western Railway locos - initially focussing on the Dean and early Churchward period as a result of research for producing the Orion Models locos

 To speed display (not everyone has high speed broadband) photos and drawings will be accessible through links - e.g. GWR Cities Image
