Economy tests have often shown a lower consumption thanindicated above—frequently less than one pound of coal perbrake horse power hour at approximately full load. The figuresgiven are of value as giving the comparative fuel consumption atdifferent loads, and for this purpose they may be considered asconservative and THE FREIGHT CAR SITUATION. Statistical bulletin No. 29, issued by thecommittee on car efficiency of The AmericanRailway Association, showed a total of 281,621surplus cars on August 5, a decrease of 27,059since the last fortnightly report. Of this de-crease 6,505 are box cars, 21,195 coal ar[d gon-dola, while surplus flat cars increased about1,000. Shop reports indicate an increase of about5,000 in the number of bad order cars, leavinga net improvement of 22,000 cars. The in-crease in bad order cars is not necessarily anindication of lack of activity in car repairs,but is probably due to the transfer of carsfrom the available to the shop column on ac-count of defects developing when cars aretaken from storage tracks for restoration toservice. The accompanying chart shows graphicallythe surpluses and shortages as taken from thefortnightly reports since January 2, 1907.
