Excerpt from Transactions of the American Society of Civil Engineers, Vol. 50: June, 1903 No locomotive has yet been built which can supply steam for an indefinite period as fast as it can be used in the cylinders, even at an economical Speed; but, by virtue of this stored energy, when the steam is at full boiler pressure, a locomotive can haul a much greater load than can be hauled continuously. In ascending a long grade, a point will be reached beyond which the possible load will depend entirely on the capacity of the boiler to produce steam for current use. The distance of this point from the foot of the grade will be a function of the momentum and this stored energy. For all grades having a length less than this distance it would be possible, therefore, to increase the rate, and, by making a correspond ing decrease in the length, not affect the maximum load. Attention is called to a practical application of this in Mr. Dennis' paper. To any engineer of experience in the location of railways, numerous examples will occur where such an arrangement will result in no small saving in construction costs.
