Both acceleration and braking are produced at the expense of weight transfer from one axle to another. The examination of the degree is normally confined to acceleration and more particularly to locomotives. It is further simplified by ignoring the acceleration of the masses of the locomotive itself. The tractive effort is regarded as drawbar pull and calculations are made on this basis. The still widely held idea is dispelled that single outside brake blocks cause more weight transfer than double blocking or single inside blocks; the net primary weight transfer is in each case the same. There is more tilt on the bogie frame with single outside blocks, and the impression could be given that the weight transfer was greater. Energy is stored to a greater degree in the springs, and its release as the train comes to rest produces the unpleasant reaction. This should not be confused with true weight transfer.
