that a guide rail is necessary under the car 

 to prevent undue swaying. 



Particular attention has been given to the 

 design of the car which is expected to 

 attain such a remarkable speed. Naturally 

 enough, the car propelled as aircraft is 

 propelled would show a tendency to rise, 

 this, however, is checked by the design of 

 the bogie. These bogies have a very small 

 wheel-base, and there are two to each 

 car, they are placed as close together 

 as possible, so that the undulations of 

 the ground can be followed without any 

 difficulty. 



There are eight shock absorbers which are

In order to ensure safe travel automatic 

 electric signalling is proposed, and this
