By Wellington table p. 173 -
95'grade to an 80'grade as 326.5 to 375 or 870 to 1000.
95' grade to an 70' grade as 326.5 to 418 or 781 to 1000.
Hence 826 to 1000 as 95' grade east to a 75' grade west.
Again p. 81. - 95' grade to a 74' grade as 3803 to 4597 or as 825 to 1000. Hence 826 to 1000 as 95' grade east to a 74' grade west. By my table given in report of October 15, 1880 - 95' grade to a 78.67 as 436 to 528 or as 826 to 1000. From my examination I would as soon trust Trautwines table as Wellingtons.
In your letter of October 4th you suggested the use of 52.8 grades west; let us examine and see what the difference in east and west frieghts should be to call for this difference.
Trautwine has 95' grade to 52.8' grade as 204 to 352 or reduced west 1000 to 577 east. We have seenheretofore that it requires 54 per cent of this for cars and engine going west and 66 per cent going east; so we would have, net load 460 tons going west to 196 tons going east, or net load of 1000 tons west and only 426 tons east.
Wellington p.81 - 95' grade to 52.8' grade as 3001 to 4597, reduced gross west 1000 to 632 gross load east, or 460 net load west to 215 tons east or - 1000 net load west to 468 net tons east.
The Union Pacific reports established the fact that the through freights east and west have been approaching an equality since 1875. For that year they were 100 west to 43 east and in 1879 they were 100 west to 77 east. In my opinion, when California has a competing line, the equalization in the proportion will again be checked for a while and that we are entirely safe in assuming the present business of the Union Pacific as an indication of the future business of our road.
Could it be known exactly what the future proportion would be, it might save the company millions. For should we reduce the west going grades below their proper proportion, then if trains are fully loaded the same the same locomotive can not haul the empty cars back with the east bound freight. It would be well to reduce the grade a little below that shown perhaps as the grades coming east would always govern the gross weight of trains, both east and west even with a considrable change in the proportion.
I had thought that a 75' grade would be the one most desirable, all things considered and have made an estimate for such change hereinafter given you. But before entering into that comparison it may be as well to take up the question of operating expenses between the Colorado Chiquito and the Colorado River on your basis of 1% grades, going west with double maximu from Diablo to Volunteer, also up to Pineveta DIvide.
