Steptoe was the first engine to be built in house at the SNBR and entered service in 1987. She is based on the Mardyke design of
locomotive, having an engine that powers a hydraulic pump, that then power 2 motors mounted on the bogie. Steptoe's name stems from the
fact that many of her pants were sourced from scrap, including part of her roof being from a very old AA sign.
Steptoe is based on the BR Class 25, and is painted in two tone green, after her initial livery of blue was considered not good enough by her builder.
Although not quite as powerful or as fast as her Mardyke stable mates, Steptoe can handle a full SNBR train, and has a certain wiggle about her when working up
the hills. Unfortunately subsequent Mardyke arrivals has ment that Steptoe has fallen out of service, and is presently gathering dust in the shed. It is expected that
she may be fitted with a diesel engine similar to that fitted on the underconstruction DMU, as it is felt her present failings are that of the engine and not of the complete power system.
