Chambers's Journal of Popular Literature, Science, and Art, No. 695 April 21, 1877.
when on the incline. Its sides are of wire-work, and are made thus with the object of reducing the weight as much as possible; an object which is also carried out both in the engine and in the carriage, which are as light as they can be made, it not being necessary to prevent the wheels jumping from the rails by the pressure of great weight as on ordinary lines, where a high rate of speed is attained. This tender, in addition to its usual functions, performs the office of carrying surplus passengers on an emergency.
The carriage is an open car, rather resembling a block of low pews taken from a church, placed on wheels, and surmounted by an awning, with curtains to let down at the sides, as a protection against the weather. The seats, which are nine in number, and accommodate six persons each, all face one way—namely, downhill; and a fixed footstool serves to keep the passengers from sliding off their seats. Contrary to the usual order, the carriage on this line precedes the locomotive in the ascent, and is pushed instead of being pulled up the incline. In the descent the locomotive takes the first place, and exercises merely a retarding force. It will be seen, therefore, that the two portions of the train are necessarily in close connection when in motion, and for this reason, as well as for purposes of safety, couplings are dispensed with. Each portion is provided with its own brake-power, so that in the event of the engine getting beyond control, the carriage can be stopped and rendered entirely independent, since it is not coupled to the engine. The brake is of course of a totally different kind from that in ordinary use, which would be of no service whatever on such inclines, as the wheels, even if the brake were so powerful as to stop their revolution, would slide down the hill by the mere force of gravity. Here, however, the brake consists in an ingenious adaptation of the means which are employed in driving the engine.
The roadway is laid with three rails, the outer ones being of the usual kind, while the central one is a long-toothed rack, of which the teeth are perpendicular. Into this rack fit the teeth of the pinions or cogged-wheels with which both engine and carriage are provided. Now it is apparent that if these wheels are put in motion they will pull the train along the rack; and if stopped and held firmly in one position, they will prevent any onward motion by the mere clinching of the teeth, to use a common expression. One of the cogged-wheels, then, which are attached to the engine is the driving-wheel, and forms the special means of locomotion, while the other cogged-wheels of course merely revolve without exercising any traction. But immediately a halt is required, all these wheels become of equal importance, and supply a prompt and most efficient brake, since directly they are locked, the train is brought to a stand-still, and held as in a vice even on the steepest inclines. Other brake-power is also applied; but this would seem to be the efficient means of control in case of accident.
It will be seen, therefore, that the danger of the train running away is carefully provided against; and no less care has been bestowed on the means for preventing the train leaving the rails, a danger fully as alarming as the other on a line which, for the greater part of its course, runs on the brink of a fearful precipice. Along each side of the central or rack rail, which is raised some inches from the ground, runs a projecting edge; and the engine and carriage are provided with two strong rods, the ends of which are bent in such a manner as to pass under these projections. Any jerk or jump of the train, therefore, would be resisted by the pressure of these bent ends against the under surface of the projections.
It is not within the province of this paper to speak of the hotels which form such huge excrescences on the mountains' sides and top (by no means an improvement on nature), or to allude to the hundreds of tourists who daily swarm in these hotels, or to the hundreds of others who take the journey for the sake of a 'new sensation.' It may, however, be mentioned that from one of the stations (Rigi Staffel) runs a branch-line which communicates with the Rigi Scheideck, where is situated one of the largest of the hotels; and that the line from Art joins the Vitznau line near the summit. It will thus be seen that the Rigi is traversed in all directions by railways; and according to the opinion of an intelligent Swiss with whom the writer conversed, these railways owe their origin to the fact that the Germans, who have now become such a travelling nation, will not penetrate in any numbers where they cannot travel by horse, by carriage, or by steam; and he further indicated his opinion of Germans by adding, that no doubt ere long, a lift would be constructed to work up and down the perpendicular face of the Matterhorn for their benefit. Who shall say that such a thing is impossible?
