Dynamometer Tests, New York Central THIS discussion touches tlie subject of the economictrain load or train speed purely from the standpointof fuel. Admitting that many times other operat-ing conditions, or costs, or returns, finally settle the ques-tion of train load, it is altogether fitting that this associa-tion approach the discussion with entire attention directedtoward the fuel consumption. The tonnages referred toherein are gross tons of 2,000 lb., not adjusted tons. A train hauled by a locomotive is a unit made up of twocomponents.
