Permanent railways run from a hundred peat bogs, each covering hundreds of acres, to power stations, briquette factories, moss peat factories and roadside tipplers. On most of the bogs, temporary tracks are laid along the piles of peat the full length of most bogs. Before a pile has been cleared, another temporary line will have been laid a few hundred feet farther along. More than 300 kilometers (approx 180 miles) of temporary track are laid each year and the Bord have specialist track fabrication workshops, tracklaying machines, and a fleet of dedicated locomotives and rolling stock on hand.
