从蒸汽机车到标准动车组 火车头见证中国铁路百年变迁
此后,电能被广泛开发运用后,电力机车开始“登堂入室”,逐步成为中国铁路的主要牵引动力。1969年,韶山型电力机车成为中国客货运列车的主力。杨溪介绍说:“这个车研制出来以后,我们又进行了更新和技术的改造,这样其中也包括引进一些其他国家的技术,最后形成了我们这个韶山系列电力机车。”
进入21世纪后,中国进一步推进铁路机车车辆装备现代化,CRH(和谐号)动车组列车,开启了中国铁路的高速牵引时代。直到今年6月26日,以“复兴号”命名的中国标准动车组首发,在京沪高铁惊艳亮相,标志着中国铁路技术装备达到了“领跑世界”的先进水平。
从引进、复制再到具有完全的知识产权,小小的火车头不但牵引着火车速度的不断提升,也牵引着车轮上的中国高速前进。杨溪说:“引进消化吸收再创新的这样一个过程以后,有很多的技术我们自己已经掌握了,基本上已经可以达到整列车全部的自主知识产权化,所以我们才能非常骄傲地说我们整个中国铁路的整套系统可以向国外来输出,因为我们已经完全掌握了这套技术。”
火车头的变迁对于火车司机来说更是颇为感慨。归华的一家三代都是火车司机,对于他来说,也终于实现了爷爷开上中国自己建造火车的愿望。“我爷爷那时候早期跑车还是抗日战争年代,那时候的机车都是外国产的机车比较多,他们那时候有个心愿就是早日能开上自行研制建造的机车。”
