The rail laid was light, 30-pound per yard (15 kg/m) rail being installed at first, increased to 50 lb/yd (25 kg/m) in 1885 and 60 lb/yd (30 kg/m) in 1904. It was, however, laid from the beginning on standard gauge-sized ties. Given the lightweight rail, the locomotives were small and of narrow gauge dimensions. The vast majority of them were Mason Bogies, 11 from the Mason Machine Works and a further 21 from other builders after Mason closed. Cars were of narrow gauge dimensions, seating four across.
