Locomotive Facts & Figures  
  Builder: Narogauge Ltd 1989   No.9 Jason 2-4-4T
      In 1986 a need for more powerful engines arose. Although the original project was to enlarge Talos, the chassis, larger cylinders and locomotive-type boiler were then used to construct a complete engine, which is Jason. The paint scheme approximates Bulleid's pre-war livery.
