Some Figures on trie Cost of Train Service. 
55 
of each railroad for periods varying from four to seven years, ending 
June 30, 1907. The cost of “locomotive service” and “other train 
service” is given separately and then summarized, and the total cost 
per train-mile, per car-mile, per passenger-mile and per ton-mile for 
each railroad, and the average for all of them, shown. These tables also 
show the average number of cars per train, the train-miles and car-miles 
per ton of coal consumed, and the ratio between the loaded and empty 
freight cars hauled, for each railroad and for all of them. 
Tables Nos. 3 and 4 show the variation in the average total cost of 
passenger and freight train service, per train-mile, of each railroad and 
for all of them, for each year of the periods given. Tables Nos. 5 and 6 
give the same information per car-mile, and Tables Nos. 7 and 8 indi- 
cate the actual expenses per revenue passenger-mile and per revenue 
ton-mile. 
Table No. 9 shows the “average number of cars -per passenger train” 
of each railroad and all of them, for each year of the periods ending 
June 30, 1907, and Table No. 10 gives the same information relative 
to freight trains. In the latter case all empty freight cars have been 
reduced to a loaded car basis,, i. e., five empties rated as two loads. 
Table No. 11 shows the average number of revenue passenger carried 
“per train” and “per car,” and the average number of revenue tons of 
freight “per train” and “per car,” by all of the ten railroads during 
each year, 1901 to 1907, inclusive. 
It will be observed from these tables that, comparing the year 1907 
with 1902 (the year 1902 is selected for this comparison as so few 
railroads are shown for 1901), the cost per passenger train-mile has 
increased from 36.78 to 42.70 cents, an increase of 16.1 per cent. The 
cost per passenger car-mile has increased from 7.12 to 7.78 cents, or 
9.3 per cent. The cost per 100 revenue passenger-miles has decreased 
from 87.41 to 78.72 cents, a. decrease of 9.9 per cent. The average 
number of passenger cars hauled per train has increased from 5.17 to 
5.49, or 6.4 per cent. The average number of revenue passengers 
carried per train has increased from 42.1 to 54.2, or 28.8 per cent, 
and the number carried per car has increased from 8.1 to 8.9, or 
22.2 per cent. 
In the case of freight trains, comparing 1907 with 1902, the average 
cost per train-mile, for the ten railroads, has increased from 58.01 to 
77.58 cents, an increase of 33.7 per cent. The average cost per car- 
mile, “equal to loads,” has increased 3.65 to 4.38 cents, or 20.0 per cent. 
The. average cost per 100 revenue ton-miles has increased from 28.24 
to 32.21 cents, or 14.1 per cent. The average number of cars handled 
per train, “equal to Toads,” has increased from 15.83 to 17.70, or 11.8 
per cent. The number of tons of revenue freight has increased from
