AVERAGE WEIGHT CALCULATION OF A FREIGHT TRAIN

Abstract

Average weight of freight trains is an important indicator of the use of the existing tonnage rating, power of traction means and defining, in terms of given volume of traffic, size of freight trains movement on sections of railway lines. This indicator plays a leading role in technical and economic calculations, but methods, which are used, provide a basis to seek corrective options. The author offers his interpretation of the well-known formula that is used for selecting optimal tonnage rating of freight trains (characterized by full-length and full-weight) and bases his calculations on certain assumptions. With the help of a modified formula difference of the calculated average weight of about 2.3% is achieved.
