Used most days when the railway is operational, Horace can usually be seen organising the coaching stock at the beginning of the day whilst also completing a track check.
The chassis was purchased from Roanoke, Bratton Fleming, North Devon. A footwell and pony truck have been added to the chassis to make it follow the Tinkerbell wheel and cab arrangements.
It was originally fitted with a Lombardini six and a half HP single cylinder diesel engine with hydrostatic drive, but was rebuilt in 2015 with a Honda 5 HP single cylinder petrol engine.
Horace was named after the dog of the head warden here at the park at the time of construction.
