Excerpt from The Electric Journal, 1914, Vol. 11 The results of the Lake Shore emergency brake tests of 1909 which appeared in the Master Car Builders' Association Proceedings for 1910, directed special attention to the important influence of the foundation brake rigging and brake shoe perform ance as affecting the stopping of modern heavy roll ing stock. These tests showed clearly the necessity for realizing, as nearly instantaneously as possible, a retarding force as high as the limitations of track and equipment would permit if emergency stops, especially at high speeds, were to be made in as short a distance as desirable.
