Re: Cumbres train register, February 14, 1933

"How did the extra westbound manage to lose 40 tons at Cumbres?"

This has been covered in a couple of threads. However, here goes. Most all freight trains were, are, operated with acutal tonnage and adjusted tonnage ratings. Adjusted tonnage is increased tonnage to allow for certain operating conditions such as slack grades, conditions of power, necessity for maintaining stock schedules or for other reasons that might affect efficient operation. Factor numbers start with "1" and could go as high as "10". The adjustment factor represents the number of tons which shall be added to the total weight of each car, loaded or empty. The actual tonnage for this train was 155 tons. Factor between Alamosa and Cumbres was 5. Take 5 x 10 cars = 50 tons to be added making a total of 205 tons. Factor between Cumbres and Chama was 1. 1 x 10 = 10 tons to be added making a total of 165 tons (adjusted)
