The electric lamps also serve the purpose of lighting up both the signal cabins and the signal posts along the line. There are three of the former mounted at the side of the track, and they contain no less than twenty-six levers, from which stretch flexible wires and runners to the signal posts. The last-named, which are twelve in number, are three feet in height, and are fully equipped with semaphores, lamps showing red, green, and white, platforms and ladders. Besides these, there are also worked from the signal cabins sixteen sets of points, by means of rod connections and levers. Every particular with regard to the signalling and the shunting has been thought out and executed with the most laudable and painstaking thoroughness and accuracy. And these arrangements decidedly add a somewhat picturesque element to the line, while they also strengthen the effect of reality which is the chief impression given by this marvellous railway. It is, of course, impossible to enumerate every matter of interest connected with the line itself, but it must be stated that there have been provided two turntables to take the locomotive and tender, and that the turntables have four levers for the points, and also that they have been furnished with spring buffers; and, further, that a tank, into which the boiler can be emptied, has been let into the track. In the course of the length of the line, the train passes through a long cutting, forty feet in extent, and two feet deep. To heighten the illusion, the sides of the cutting are covered with grass, and on the top of both sides there is a dwarf hedge. This portion of the road supplies it with its chief scenic attraction. Some distance from the cutting there is a road bridge across the railway, three feet long by two feet wide. Before reaching the second station, Beechvale, a long and fearsome tunnel has to be negotiated--its actual length is eighteen feet. The station-house, platform, and other accessories of Beechvale are very similar to those at Oakgreen. [Illustration: TURNTABLE FOR THE ENGINE AND TENDER.] The locomotive, with its tender, is five feet long and about eighteen inches in height. It is of six-inch gauge, and is an exact duplicate on a small scale of an express of the London and North-Western Railway. It is a real working locomotive, most exquisitely made. The only points in which it differs from its model are such as come from its comparatively diminutive size. Thus, its boiler has not the usual number of tubes, it has no injector, and steam is got up in it by a charcoal fire, the charcoal being kept at a great heat by a "blast."
