is more favorable in the return trip than in the tripgiven in the schedule. The average speed for the stops is 55.4miles, so that the average time or the average distance—1475 ft.—which have been made the basis of this schedule, exceeds the aver-age distance on the basis of stops that have been made undersimilar conditions with the quick-action brake and exceeds theaverage of those stops about 20 per cent. This I should think wasan abundant allowance for difTerence in atmospheric rail con-ditions and that sort of thing, and these stops, made on thePennsylvania road and other places where I have obtained data,which has enabled me to make these computations; the condi-tion of the rail was good, that is to say, it was a good clear day.There was no moisture or frost on the rail, and of course thosestops were under conditions where there is moisture on the railor frost, in which case the stops would be longer than those madeunder favorable conditions. The 20 per cent allowance made in

FIG. 12.—RUN SHEET FROM RYE TO PORT CHESTER the emergency brake? A. I believe that it would be a very de-sirable thing to do, especially if it is desired to make a very fastschedule. I think it is not only desirable but very much so. Q. Have you seen a schedule of the express train stops contem-plated in the operation of the New York & Portchester Railroad,and if so, what do you find to be the average time and averagedistance in which a train could be stopped in the operation of thisroad, using a Westinghouse brake? A. The schedule which Ihave been given provides for eleven stops, one at 149th Streeton a descending grade of 14.9 ft. to the mile, from a speed of 59.7miles per hour. The second, at Bronx Park, an ascending gradeof 9.1 ft. to a mile, at a speed of 62.7 miles; the third at B. P. andP. P. on an ascending grade of 27 ft. to the mile, at a speed of60.4 miles. At Mt. Vernon on a descending grade of 38.5 permile at a speed of 57.7 per mile. At Pelham at a speed of 50miles
