It is well known to railway operating men that a run at a hil1, especially a short one, is a great help toward getting the train over it. The tonnage rating for heavy freights, over probably every road in America, is greater than the load that can be started at certain points. The engineering departments of our railways know, in a general way, that mome ntum is of some help, but few have attempte d to take ad vantage of it when fixing grades, or have investigated to what limits it could be used.
During the past year more than 3 000 miles were run by the writer, with a dynamometer, on heavy freight trains loaded much beyond the rating for the ruling grade, to see what minor grades could be run with momentum, and where the stalling poipt was on those which could not be run.
