PETERSFIELD].—RAILWAY ACCIDENT.—On Saturday last a serious accident occurred on the Direct Portsmouth line. It appears that as the up express train, due here at 11.32, was just emerging from the tunnel at Buriton, the whole of the carriages ran off the line, the engine becoming embedded some two feet in the earth. It was a most providential circumstance that the accident did not occur a few yards farther up, nor on the opposite side of the line ; in either case the consequences must have been fearful, as it was no one sustained any injury, and the passengers were speedily got off the train and brought on to Petersfield in omnibuses, &c. The up and down trains were delayed considerably throughout the day, and as of course none could pass the damaged pieces, it being only a single line, the passengers were taken to the Buriton side of the tunnel, where they were obliged to alight and walk to another train, which was waiting to take them on. The damage was repaired by eleven o’clock on Saturday evening, and the traffic proceeded with its accustomed regularity. It is conjectured that the mishap was caused by a defective sleeper, near the Buriton tunnel. Fortunately the Inspector of the loop line, Mr. Dyson, of Guildford, was riding on the tender with the engineer at the time, and this being a single line of rail, Mr. Dyson, with his usual promptness, hastened on to the Petersfield Station and put the telegraph communication into operation, to prevent any further accident. This being done, a special train, with the traffic manager at the head, A. Scott, Esq., was on the spot within three hours, with a suitable staff of about 40 men, and within a few hours, the line was cleared of the debris, and the following morning the trains ran as usual. It is gratifying to state that no one received the least hurt whatever, neither were engine or carriages the least damaged.
