电气化铁路电气化铁路electricrailway用电力机车作为牵引动力的铁路。世界上第一条电气化铁路于1879年在德国柏林建成。中国于1961年建成第一条电气化铁路——宝成铁路的宝鸡至凤州段。电气化铁路问世后发展很快，法国、日本、德国等国家已成为电气化铁路为主的铁路运输业，大部分货运量是由电气铁路完成的。电气化机车上不设原动机，其电力由铁路电力供应系统提供。该系统由牵引变电所和接触网构成。来自高压输电线路的高压电经牵引变电所降压整流后，送至铁路架空接触网，电气机车通过滑线弓受电，牵引机车行驶。供电制式分为直流制。电气化铁路与现有其他动力牵引的铁路相比，具有的优越性是能源节省，其热效率可达20%~26%；运输能力大，功率大，可使牵引总重提高；运输成本低，维修少，机车车辆周转快，整备作业少、耗能少；污染少，粉尘与噪声小，劳动条件也较好等。中国川黔电气化铁路
