    Overweight

    Been doing some experimenting on train weights.

    I created a consist of one loco (SD70M) and 91 high cube boxcar loads. Turns out the average weight of each loaded car was 120.75 US Tons. (10,988 tons / 91 cars). I could barely move the train. Run 8, needle in the 5 min red zone, highest speed I attained was 0.5 mph.

    On line, I found some real world train stats and did some calculations. I completely ignored the empty car count, and divided weight by loaded cars

    Railcars can either weight out or cube out. Weigh out means filled to weight capacity even if car is not completely full. Cube out is fill car completely full even though the weight is no where close to the car's max weight limits.

    It seems as though way too much of our rolling stock in sim world is default set to weight out, rather than cube out. Which possibly makes the average car (and train) heavier than in real life.

    Does anyone have additional real world train stats that allow us to calculate the average weight per load for various commodities? Coal is a commodity that probably gets closer to weighting out, but other types of loads probably cube out more often in real life.

    Found a few pieces of paperwork from before I left the railroad - by no means a comprehensive list and may be regionally dependent (upper midwest) but some data for your research project 😁
