As regards electric railway accidents and blockings of tubes, the _Advocatus Diaboli_ is able to quote rather too many examples. Commencing with the United States, where in July, 1902, a car, descending the mountain on the Mountain and Lake Electric Railway, near Gloversville, where the grade is a thousand feet in four miles, became uncontrollable, and, acquiring frightful velocity, collided with another car which was ascending the slope. Both cars rushed down several feet, and then ran off the rails. Each car contained seventy passengers, and of these fifteen were killed and injured. Ten bodies, mangled beyond recognition, were taken from the wreckage. Most of the victims were women. At home there is the disastrous Liverpool Electric Overhead Railway fire of December 23rd, 1901. The trains are run on the multiple control principle, a motor at each end, and the accident was due to a defect in the rear one. But as it is a typical case, I will quote in full the cause of the accident, as assigned by Lieutenant-Colonel H. A. Yorke, the Board of Trade Inspector. He says: “A gale of wind was blowing from the west, that is, from the mouth of the tunnel towards the station, which caused the fire to spread from carriage to carriage until the whole train was enveloped in flames. It is estimated that the train was well alight about twelve minutes after the stoppage. There were twenty-nine passengers, who, when the train first came to a stand, were urged by the driver and guard to keep their seats, as there was no danger. The driver and guard seem to have made some futile attempts to put out the fire; but it soon became apparent that the fire had obtained the mastery, and the passengers found it necessary to alight. They had only eighty yards to walk in order to reach the station, and the majority of them appear to have gone to their homes without any delay, and to have suffered no ill-effects from the fire. It appears, however, from the evidence that a few remained behind, presumably to watch the progress of the conflagration and the result of the effort to control it.”
