As it approached the point where the disaster occurred the special train was running at a moderate rate of speed, not probably exceeding twenty miles an hour. The engineer of its leading locomotive also perceived his danger in time to signal it and to reverse his engine while yet 700 feet from the point where derailment took place. The train-brake was necessarily under the control of the engineer of the second locomotive, but the danger signal was immediately obeyed by him, his locomotive reversed and the brake applied. The train was, however, equipped with the ordinary Westinghouse, and not the improved automatic or self-acting brake of that name. That is, it depended for its efficiency on the perfectness of its parts, and, in case the connecting tubes were broken or the valves deranged, the brake-blocks did not close upon the wheels, as they do under the later improvements made by Westinghouse in his patents, but at best remained only partially set, or in such positions as they were when the parts of the brake were broken. As is perfectly well understood, the original Westinghouse does not work quickly or effectively through more than a certain number of cars. Twelve is generally regarded as the limit of practical simultaneous action. The 700 feet of interval between the point where the brakes were applied and that where the accident occurred, – a distance which, at the rate at which the train was moving, it could hardly have passed over in less than twenty-two seconds, – should have afforded an ample space within which to stop the train. When the derailment took place, however, it was still moving at a considerable rate of speed. Both locomotives, the baggage car and six following passenger cars left the rails. The locomotives, after going a short distance, swung off to the left and toppled over, presenting an insuperable barrier to the direct movement of the cars following.
Those cars were of the most approved form of American construction, but here, as at Shipton, the violent application of the train-brakes and reversal of the locomotives had greatly checked the speed of the forward part of the train, while the whole rear of it, comparatively free from brake pressure, was crowding heavily forward. Including its living freight, the entire weight of the train could not have been less than 500 tons. There was no slack between its parts; no opportunity to give. It was a simple question of the resisting power of car construction. Had the train consisted of ten cars instead of twenty-two a recent experience of a not dissimilar accident on this very road affords sufficient evidence of how different the result would have been. On the occasion referred to, – October 13, 1876, – a train consisting of two locomotives and fourteen cars, while rounding a curve before the Randolph station at a speed of thirty miles an hour came in sudden collision with the locomotive of a freight train which was occupying the track, and while doing so, in that case also as at Wollaston, had wholly neglected to protect it. So short was the notice of danger that the speed of the passenger train could not at the moment of collision have been less than twenty miles an hour. The freight train was at the moment fortunately backing, but none the less it was an impassable obstacle. The three locomotives were entirely thrown from the track and more or less broken up, and three cars of the passenger train followed them, but the rest of it remained in line and on the rails, and was so entirely uninjured that it was not found necessary to withdraw one of the cars from service for even a single trip. Not a passenger was hurt. This train consisted of fourteen cars: but at Wollaston, the fourteen forward cars were, after the head of the train was derailed, driven onward not only by their own momentum but also by the almost unchecked momentum of eight other cars behind them. The rear of the train did not leave the rails and was freely moving along them. By itself it must have weighed over 200 tons. The result was inevitable. Something had to yield; and the six forward cars were accordingly either thrown wholly to the one side or the other, or crushed between the two locomotives and the rear of the train. Two of them in fact were reduced into a mere mass of fragments. The disaster resulted in the death of 19 persons, while a much greater number were injured, more than 50 seriously. In this as in most other railroad disasters the surprising thing was that the list of casualties was not larger. Looking at the position of the two cars crushed into fragments it seemed almost impossible that any person in them could have escaped alive. Indeed that they did so was largely due to the fact that the season for car-warming had not yet arrived, while, in some way impossible to explain, all four of the men in charge of the locomotives, though flung violently through the air into the trees and ditch at the side of the road were neither stunned nor seriously injured. They were consequently able, as soon as they could gather themselves up, to take the measures necessary to extinguish the fires in their locomotives which otherwise would speedly have spread to the débris of the train. Had they not done so nothing could have saved the large number of passengers confined in the shattered cars.
CHAPTER IV.
ACCIDENTS AND CONSERVATISM
The four accidents which have been referred to, including that of April 17, 1836, upon the Manchester & Liverpool road, belong to one class. Though they covered a period of forty-two years they were all due to the same cause, the sudden derailment of a portion of the train, and its subsequent destruction because of the insufficient control of those in charge of it over its momentum. In the three earlier cases the appliances in use were much the same, for between 1836 and 1874 hardly any improvement as respects brakes had either forced its own way, or been forced by the government, into general acceptance in Great Britain. The Wollaston disaster, on the other hand, revealed a weak point in an improved appliance; the old danger seemed, indeed, to take a sort of pleasure in baffling human ingenuity. The Shipton accident, however, while one of the most fatal which ever occurred was also one of the most fruitful in results. This, and the accident of April 17, 1836, upon the Manchester & Liverpool road were almost precisely similar, though
