 At least four contractors' locomotives were used for construction. Unusually, some of the temporary track was wider than the final gauge - the section around Parracombe Bank for example, spanning the Heddon valley, was built to 3 ft (914 mm) gauge, with a locomotive known as Winnie. A fifth locomotive - perhaps named Spondon - may also have been used, although little is known of either of these. In 1900, Kilmarnock was sold by the L & B. It is believed to have been left behind by James Nuttall, as a result of the financial problems and litigation between railway and contractor.
