The average speed in these experiments was 47 miles, and with the train-brake, according to the foregoing tabulation, the stop should have been made in about 250 yards; in reality it was made in a little less than five times that distance, or 1120 yards; in other words the experiments showed that the improved appliances had more than quadrupled the control over trains. It has already been noticed that in the cases of the Angola and the Port Jervis disasters, as well as in that at Shipton, the trains ran some 2,700 feet before they could be stopped. Under the English tabulations above given, in the results of which certain recent improvements do not enter, a train running into the 42d Street Station in New York, at a speed of forty-five miles an hour when under the entrance arches, would be stopped before it reached the buffers at the end of the covered tracks.
