Between the rails runs a third broad and massive rail provided with teeth,
which gear with a cogwheel under the locomotive. The train is propelled
upward by steam power, while in its descent the speed is regulated by an
ingenious mode of introducing atmospheric air into the cylinder. The
carriage for the passengers is placed in both cases in front of the
engine. The larger carriages have 54 seats, and the smaller 34. Only one
is dispatched at a time. In case of accident, the train can be stopped
almost instantaneously.

We give herewith, from _La Lumiere Electrique_, several engravings
illustrating the system. Fig. 1 shows the starting station. As may be seen
on Figs. 2 and 3, the method selected for obtaining adhesion permits of
ascending the steepest gradients, and that too with entire security.

HIGH SPEED STEAM ENGINE.


The use of rapidly rotating machinery in electric lighting has created a
demand for engines running from 400 to 1,200 revolutions per minute, and
capable of being coupled directly to a dynamo machine. We have already
illustrated several forms of these engines, and now publish engravings of
another in which the most noticeable feature is the employment of separate
expansion valves and very short steam passages. Many high-speed engines
