at least three builders' engines were used for building the line. unusually, some of the temporary track was wider than the final gauge - the section around parracombe bank for example, crossing the heddon valley, was built to gauge, with an engine known as "winnie". a fifth engine - perhaps named "spondon" - may also have been used, although little is known of either of these. in 1900, "kilmarnock" was sold by the l&amp;b. it is thought that it was left behind by james nuttall, because of the financial problems and legalcase between the railway and the builder.
