特快旅客列车制动距离换算坡度的计算方法

Calculation Method of Equated Gradient of Brake Distance for Express Passenger Train

铁路三次提速后 ,特快客车、快运列车、行包列车速度达到 1 2 0～ 2 0 0km h,列车制动距离超过 80 0m时的线路换算坡度与原来不同 ,对此提出了新的计算方法。遇有其他类似情况也可采用此法。

After the three speed raising in railway, the traveling speed of express passenger trains, fast passenger trains and baggage & parcel trains now reaches 120～200 km/h. Hence the equated gradient when trains' brake distance exceeds 800m is not like what it used to be. This article puts forward a new calculating method regarding this and suggests that this method also applies under similar circumstances.
