Locomotive Facts & Figures  
  Builder: A Oliver & G Oliver   Guinevere
      Guinevere was started in 2001 as a father and son project. The engine is based on Horton but fitted with Walschaerts valve gear, a larger boiler and larger cylinders, making it a more capable locomotive by combining attributes of Horton & Hartfield. The livery is blue with red lining. The engine took 13 years to construct - it was completed in July 2014 and named at the Railway Open Day in March 2015.
