Apart from factories, there are many coalmines, some closed now, and some with fires burning deep in the mineshafts. The mining area extends for a large area, mostly to the south of the tracks. Quite a portion of the track passes through cuttings, where the surrounding area is higher than the track level, resulting in the profusion of characteristic small masonry bridges crossing the tracks."
