2.19. SECOND DIVISION NDT
The discussion of the NDT for the remaining two divisions is
much briefer; however, the necessary computations are presented for
you to follow.
The drawbar pull of the 0440 dieselelectric locomotives used
on the 2d division is given as 33,600 pounds in paragraph 2.17b,
Therefore, the first computation is for gross trailing load (GTL).
The second computation is for net trainload (NTL)
NTL = 50% of GTL
NTL = .50 x 621
NTL = 310+, or 311 STON
The third computation is for train density (TD).
