Lightweight Expresses Evolved by French Engineers
THE BUGATTI PETROL-
IT has fallen to France to play an important part in the development of the express rail-
It is in this connexion that the rail-
In France Les Autorails, as they are known, are specially built for certain services. There are high-
Some types of rail-

Easy running is further assured by heavy longitudinal springs, with which the two bogie supports are attached to the main bogie frames.
Each support of the power bogie is joined by flat steel springs to the bearings of the carrying and driving axles respectively. The arrangement thus consists of two carrying wheels linked by springs to a pair of driving wheels, followed by another two driving wheels and their adjacent carrying wheels.
The wheels are remarkable and consist of a “dished” centre with an internal brake drum similar to that in use on a motor-

The power plant is situated in the centre of the motor-
The engines work independently, and one, two, three or all four of them at once can be run as required. Each motor is provided with an electric starter and a radiator.
The operating gear of the Bugatti trains is very simple, since the engines are controlled by the throttle.
The chassis of each vehicle comprises two longitudinal girders of pressed steel joined together by cross-
The control position is unusual, since it is arranged with lookout windows that give a clear view over the roof of the train when running in either direction. In this control room the driver has the electric press-

THE CONTROLS OF THE BUGATTI EXPRESS. In the foreground of this picture is the handle for operating the hand brakes. Immediately above this are the four levers that control the throttles of the engines. To the left of these levers are the push buttons of the warning bell and syren, and on the right is the control for the air brake. The four dials shown give the revolutions of the engines, and below these are the various electric controls for starting and stopping, together with others that regulate the oil supply and the lighting of the train.
The Northern railways of France have some large and fast motor trains on the Lille and Paris route, each consisting of three coaches. The first coach has, at the front end, a motor compartment containing a 12-
The braking arrangements on these trains comprise an oil-
These trains, like the Bugattis, are built on steel chassis with metal body-

Many fine speed records stand to the credit of the French rail-
Speed was not, however, the only consideration of the French engineers when they were designing their rail-
THIS IMPOSING STREAMLINED EXPRESS has a speed of over 80 miles an hour, and runs on the Northern Railways of France between Lille and Paris. The train is electrically driven, current being supplied by the generators of two 12-
The expedient of warming the air supply to the coaches by means of the engine radiators has also proved successful. Another feature that has greatly contributed to comfortable travel in these trains is the employment, where-
