Some versions did away with the rear passenger carrying area and used this section for tools and even a diesel generator or air compressor. It was capable of pulling a trailer wagon with tools, but was then restricted to a two-man crew. In New Zealand, two 4 man trolleys were built primarily as track inspection trolleys, one dedicated to each island.
Powertrain
Early models of the permanent way maintenance ganger's trolley used a vee-twin JAP engine. This drove through a large flat flywheel and a friction drive. On later models a standard four-cylinder motor car engine, e.g. the Ford Angliacar 100E engine, provided power through a standard three-speed gearbox to a final chain drive transfer gearbox which included the forward and reverse selection.
Other products and services
General engineering
Early products and services provided by D Wickham & Co included castings, brewery equipment and car repairs. Wickham built their first railcar, for the gauge Taltal Railway in Chile, in April 1922. Their last was outsourced in 1991. Including a few railcars built by their successors in the 1990s, nearly 12,000 vehicles of many varieties were produced to their designs. Railcars built for British Rail included:-
There are two extant railcars based on the Isle of Man Railway, one of which is in operational condition and based at Douglas Station, used for annual transport galas; the other vehicle is stored out of use at Castletown Station. These two examples are both gauge. Further examples were used on the Snaefell Mountain Railway by the Civil Aviation Authority to access masts at the summit, and one version with toastrack seating from the Queen's Pier Tramway in Ramsey which was to gauge. This particular vehicle had open sides and was used in addition to a Planetpetrol locomotive which remains extant at the Manx Transport Museum in Jurby whilst the railcar was relocated to the Isle of Man Railway in 1975 to provide transport when the lines to Peel and Ramsey were lifted. It was later scrapped by the railway in 1978.
