The merits of rail traction underground are discussed together with the limitations of existing prime-movers. Two new prime-movers are examined, and the promising liquid-nitrogen engine is described. Various means of dealing with gradients to a steep for ordinary locomotive haulage are considered, and certain aspects of rope haulage which merit special developments are examined. The use of prefabricated fixed-length panels of conventional track is recommended for gate roads. Reasoned arguments are developed for the adoption of 760 mm track gage as a national standard for new collieries, and similarly recommendations are given for a standard coupling. An important improvement to supplies cars is described. Operational recommendations include a well-disciplined use of loops and pass-byes, and a much wider use of stop lines at fouling points on converging roads.
