大秦线上运行的两万吨运煤列车长度可达7公里，由大功率电力机车牵引，大大降低了运营成本。
Along this line 20,000-ton coal trains can reach a length of over 7 km pulled by powerful electric locomotives over an extra heavy duty track and driving down operating costs.
振动加速度峰值受轮轴荷载的影响较大，基本上呈线性增加趋势； 而列车长度对振动加速度的影响较小。
The effects on the ground vibration by the factors such as the length, the load and the speed of the train are analyzed.
