The first one of the pair, "Robert Wynn", built in 1980 was based on an original Bagnall 0-4-2T prototype. "Lady Phyllis" was built in 1997 on similar lines and in detail closely follows the tank engine design, although finished as an 0-6-2 narrow gauge tender locomotive.
Neither engine has run in some years, both have suffered in storage. Paintwork is poor, brightwork has a good covering of surface rust.
Underneath is a very well-built locomotive, obviously designed for sustained passenger hauling with generous bearing surfaces and piped lubrication to just about every moving part. The locomotive is fitted with a steam brake.
We've done an ultrasonic survey of exposed parts of the boiler, it shows no sign of leak or deflection under twice working pressure hydraulic test.
