Rail Track and Associated Equipment for use Underground in Mines
O14 group member Bob T has pointed out a very useful publication available from the HSE which provides Guidance on selection, installation and maintenance of rail track and associated equipment for use underground in mines. It provides a valuable insight into many aspects of prototype narrow gauge track construction some of which is equally applicable to above ground track.
