Not illustrated. 1905 Excerpt: ...one in which density of traffic is measured in train-miles per mile of line, it will be seen that amount of traffic does not afford an explanation of this increased liability to collisions. An increase of 305 per cent, between 1898 and 1903 is observed in Group II, where traffic is densest, and 300 per cent, in Group X, where traffic is least dense. TABLE XVIII. DENSITY OF TRAFFIC IN THOUSANDS OF TRAIN-MILES PER MILE OF LINE. The above table has a certain significance on its own account. It shows how much denser railway traffic is in the United Kingdom than in the United States and Canada. 18,600 train-miles per mile of line means that on the average 51 trains pass over each mile of line in the United Kingdom every twenty-four hours, Sundays included. It also shows that the density of traffic in the United States, measured in this way, has not been increasing, but has rather fallen off since the early nineties. This signifies that the growth of traffic, measured in train-miles and passenger-miles, has been distributed over longer lines and bunched in heavier trains, which would seem to indicate that the train despatcher's duties are no greater than before. But whether the fault is with the brain that issues orders or in the one that receives and executes them does not matter, so long as the results are the same. The facts brought out in this array of statistics indicate that something is radically wrong with the methods of operating railroads practised in this country. The case against the roads is not so bad as it appears at first sight, yet there is apparently room for improvement in nearly every respect. The record of collisions, always bad, has been growing steadily worse in spite of improvements in available devices for their prevention, which the expe.
