Considerations on the Evolution of Systems of Braking of Railway Vehicles.

In the conventional systems of compressed air braking of railway vehicles, the conditions and technical definitions are widely regulated by organisms on an international level. The article, after having illustrated the logic which gives rise, in the problem of braking, to certain technical-practical definitions of more general interest, dwells upon the principal types of brakes in use today, with considerations on their performance and on the limits of employment.
