The accompanying Table VII, Column a, gives the operatingcharges for all steam railroads of the United States, as taken fromthe Interstate Commerce Commission Reports, and divided in accord-ance with the above named items. Taking the items up in order wehave the following statement by before the British Instituteof Civil Engineers, Mercy railway records for threeyears of steam traction show that the effect of electric tractionon the maintenance of the permanent way has been to reduce the costof maintenance per ton-mile from cents to is equivalent to a saving of #. This figure for the railroads of the United States for 1910. H was cents per ton-mile which, if reduced to cents per tonmile is equivalent to a saving of 25/£, which figure has been used. As to the second item, Repairs and renewals of locomotives,-Stillwell states that the maintenance and up-keep of electric f locomotives may be placed at 2%fo per annum, while the rate for steamlocomotives is 20# per annum, which, when considering the cheapercost of steam locomotives , is equivalent to a saving of &0fc. Pomerey states the reduction in maintenance cost of electriclocomotives below steam locomotives is 60^. Burch makes the reduction ^. Taking the average of this data makes the saving in repairsand renewals of locomotives ^. Burch summarized the saving effected by electric tractiondue to reduction in engine and roundhouse wages at 36^, The same authority places the saving on all other items,except fuel and power for trains, at 2-§^& and makes an addition ofVfo of the to
