three divisions. Your problem is to determine the end delivery
tonnage at the railhead, or end of the rail line.
a. First division.
Length of line.......................105 miles.
Track................................Good to fair.
Percent of ruling grade..............1.5.
Ruling curve.........................2.5.
Temperature (lowest expected)........0 to +15
Motive power.........................0660 dieselelectric,
127ton road locomotives.
(Use data in table I).
Number of effective passing
tracks..............................12.
b. Second division.
Length of line.......................10 miles
Track................................Good to fair.
Percent of ruling grade..............1.8.
Ruling curve.........................5.
Temperature (lowest expected)........1 to 10.
Motive power.........................0440, dieselelectric,
120ton locomotives,
drawbar pull 33,600
pounds each.
Number of effective passing
tracks..............................6.
c. Third division.
Length of line.......................96 miles.
Track................................Good to fair.
Percent of ruling grade..............1.2.
Ruling curve.........................3.
Temperature (lowest expected)........0 to +15.
Motive power.........................Same as first division.
Number of effective passing
tracks..............................11.
Because the end delivery tonnage is the same as the net
division tonnage of the most restrictive division, you must determine
the NDT for each division.
