2. The Beech Wood Tunnel (situated about five miles north of Coventry, and about 300 yards in length) was entirely relined with bricks. Two hundred workmen were employed in this troublesome operation for about six weeks without a single accident, and without stopping the public, who, indeed, probably, during the whole period of the repair, passed through without being even aware of the execution of the job. 3. Between June, 1845, and October, 1848, the Company’s engineer of the Southern District relaid 57 miles of single line of railway without stopping a train and without accident. At the Agricultural Meeting at Northampton in July, 1847, upwards of 11,000 persons were sent to Northampton, and 13,000 returned in the evening, the carriages they occupied forming one mass as far as the eye could reach. From the Company’s returns it appears that, of the above number, not a single person received any injury; and although, from some unaccountable reason, a good many of them on their return walked, it is whispered, zigzaggedly, only two out of the whole number were despatched to wrong destinations. As the above facts require no comment, it is merely necessary to explain by what description of arrangements the works of a great railway can be repaired and renewed without stopping the public. The two following specimens of the directions issued on such occasions by the Company’s superintendent will best give the information required:-- LONDON AND NORTH-WESTERN RAILWAY. _Superintendent’s Office, Euston Station, 22nd January, 1848._ RELAYING THE RAILS IN THE KILSBY TUNNEL. The Engineer Department have given notice that the workmen are ready to commence removing the stone blocks and relaying the rails in the Kilsby Tunnel. The Electric Telegraph having been laid through the Tunnel, the work is to commence on the night of Wednesday the 2nd of February, and during its continuance the traffic is to be conveyed over one Line from the passing of the Up Lancashire Express Train (say 9 P.M.) until 8 o’clock the following morning, when the Up Line is to be clear for the passage of the 7 A.M. Train from Birmingham. The passage of the Trains through the Tunnel during the night is to be under the following regulations:-- The _Red_ Signal is to be kept on at each entrance to the Tunnel during the hours the traffic has to pass over the same Line; and every Train, whether Up or Down, is to stop short of the Cross Road laid down at the Tunnel mouth. As a guide to the Drivers where to stop, a Post has been erected, upon which a Red Light will be shown, and beyond which the Engine is not to advance.
