电力机车不用上燃料和水,只添加一些砂子和润滑油脂,整备一次可在一般线路上连续运行几千公里,在推行长交路、轮乘制,提高机车运用效率,减少机务设备投资方面,具有蒸汽机车无可比拟的优越性。然而,目前由于对全国路网建设 Electric locomotives do not have to use fuel and water. They only add some sand and lubricants. They can run a few thousand kilometers continuously on normal lines. In terms of implementing long routes and round trip systems, improving locomotive utilization efficiency and reducing investment in maintenance equipment, With steam locomotive unparalleled superiority. However, due to the construction of the national road network at present
