900 x .50 = 450 short tons NTL
NDT = NTL x TD
NDT = 450 x 11
NDT = 4,950 STON (3d division)
EDT = 4,950 STON
The 3d division has the smallest NDT of the three
divisions; therefore it is the EDT for the railroad.

NOTE: Only 7 passing tracks should be counted because
those at mileposts 39 and 42 are less than 5 miles
apart. An average speed of 10 mph should be used
because the ruling grade is 1.2. Even though the track
is rated exceptionally good, the most restrictive factor
governs.
