Calculating Method of Distance Between Railway Out-of-Gauge Goods and Freight Car on Adjacent Track

At present, the distance between out-of-gauge goods and freight car on adjacent track is calculated without considering the influence of length and the calculating point position of out-of-gauge goods. Furthermore, the relative position between out-of-gauge goods and freight car on adjacent track is ignored. This paper puts forward the most unfavorable stop position and the most massive space occupied by the stationary car, which is the foundation of calculation of distance between out-of-gauge goods and freight car on adjacent track. Some formulae of calculating the distance between out-of-gauge goods and freight car on adjacent track, including the formulae whenever the calculating point is located between or beyond the center pins of two bogies of cars on tangent and curved tracks, were deduced and examined. The results indicate that the meeting condition of out-of-gauge goods and freight car on adjacent track according to these formulae will be more reasonable and safer.
