Unlike the Listowel mono-rail line, the Manchester and Liverpool express is fenced from end to end with an unclimbable barrier, and as there are no level-crossings and no means of access, there is no possibility of trespassing. Also, for the security of the workmen employed in maintaining the track as on an ordinary railway--the system of “packing” the sleepers and inspecting the various parts being common to all railways--a clear space of three feet is left between the passing trains, and strong posts, ten feet apart, are fixed along the centre of the space for the labourers to hold on by when an express rushes by. Collisions, our broker quickly perceives, are impossible, there being no switches, and notwithstanding the multitude of passengers (some twenty thousand per day) there are never more than two cars on the line at a time, and there are no stoppages between the two termini. For signalling purposes, the line is divided into four sections of about five miles each, and as the train passes by, its electric motor automatically operates the signal and immediately “blocks” the section behind it, so that the train following cannot advance until its leader has cleared the five-mile division. The driver and conductor are both together in the front part of the train, so that the conductor has ample time to look out for the signals, to apply the brakes, and assist his mate. The brakes are of the Westinghouse pattern, and the two combined can stop the cars in about 800 yards, even at the speed of 110 miles an hour. These can be aided by Mr. Behr’s ingenious device, which Sir William H. Preece considers quite practicable, viz. louvres or shutters, which, when opened, materially increase the air resistance. Past Toxteth Park, Garston, Halewood, Widnes (whose only rival in sheer ugliness is perhaps London’s Stratford-by-Bow), and exactly half-way, Warrington, conspicuous for the inkiness of its river Mersey, and noted for its glass, wire, and chemical industries; famed for its network of waterways, especially for the great but evil-smelling ship-canal; noted in history--when but a hamlet, with a clear trout-yielding stream--as the camping-ground of the young Pretender when on his march to Derby in 1745; and associated with Mrs. Gaskell (whose “Cranford” is identified with Knutsford, a neighbouring village), the two Bishops Claughton, Viscount Cross, Luke Fildes, R.A., and “Warrington” Wood, the sculptor.
