525 and most efficient type of equipment. Further data are given in vhe section on Machinery and Railway Equipment (page 379 of Com- merce Yearbook). Table 16 shows installations and retirements of locomotives and freight cars since 1913, and the number and capacity of those in service at the end of each year. While the number of new cars annually installed has decreased since 1923 the average capacity and number in service has increased. Fewer locomotives were in service in 1925 than in immediately preceding years, but the average size has grown steadily, and the aggregate tractive effort in use is con- siderably greater than a few years ago.

Exclusive of electric locomotives. ' Includes both Class I and Class II. Partially estimated from unofficial sources, Source: Interstate Commerce Commission. Condition of Equipment. The ratio of unserviceable to total number of freight cars for the year 1925 was 7.7 per cent and the corresponding ratio for freight and passenger locomotives 17.9 per cent. These ratios are lower oven than the low averages of 1924 and decidedly better than those in 1922. Because of high car surpluses it was natural that somewhat less effort was made than in 1923 and 1924 to cut down further the number of unserviceable cars. The figure for unserviceable locomo- tives closely approaches the 15 per cent set as a goal by the railway executives. During 1921 and 1922 the proportion of unserviceable equipment was extremely high, reaching 15.5 per cent for freight cars during one month in 1921 and 28.9 per cent for locomotives at one time in 1922, The great amount of motive power and equipment installed during the last few vears and the small percentage of locomotives and cars
