5.3. DIESELELECTRIC LOCOMOTIVES
The average fuel requirements for standard U.S. Army locomotives
are listed in table VIII. It shows the oil for dieselelectric
locomotives used in road service in gallons per train mile and that
for switch engines in gallons per hour of operation. Using the
information in the table, the amount of oil required for both road
and switch engines can be computed as explained in the following
subparagraphs.
a. Road engines. Roadengine fuel is based on the number of
trains run daily, the length of the division, and the fuel
consumption rate of the locomotive. To find the fuel required for
dieselelectric road engines, multiply the number of trains run daily
over the division (the train density) by 2 for twoway traffic.
Multiply the result by the length of the division to get the number
of train miles per day for the division. Remember that when more
than one type of road engine is used, the number of train miles for
each type must be computed separately. By continuing this procedure
for each division and totaling the results, you can find the number
of train miles per day for the entire railroad. In table VIII, find
the fuel consumption factor for the particular locomotive you intend
to use, and multiply the total train miles by that factor. The
result is the total gallons of fuel used per day. Then multiply the
gallons per day by 30 to find the amount used per month and, finally,
add 5 percent to the total to allow for contingencies.
As an example, suppose you are going to operate a twodivision
railroad using 0440, 60ton locomotives on both divisions. The
first division is 96 miles long and has a TD of 8, and the second
division is 102 miles long with a TD of 9. Compute the fuel
requirements for the locomotives to operate the railroad as follows:
