Transportation of iron ore: a practical exercise in environmental control.

At a very early stage in the planning of high speed iron-ore trains, British Rail and the British Steel Corporation concerned themselves with the possible environmental effects from iron ore "blow-off". The trials were run, the first, using a wind jet at the Royal Aircraft Establishment, Farnborough, indicated that problems could arise from certain ores. The second trial was run on the main line between Llanwern, near Newport, and Swindon, a distance of 50 miles, at full operating speed and this confirmed the earlier findings. Control measures were tried and successfully contained the "blow-off". Facilities for dust control designed with the experience gained from the trials have been incorporated at the appropriate loading sites.
