我国第一个减速器与减速顶结合的点连式调速系统在哈尔滨站下行场取得良好运营效果以来,先后在许多编组站因地制宜得到了推广应用,有用脱鞋道岔代替减速器的(如娄底站等),有在减速器后面打靶的(如西安东站),还有在脱鞋道岔后面也打靶的(如成都东站)。其中,西安东站的点连式调速系统,由于在减速器后面打靶一段距离,一是增加了对溜放勾车尤其是难行车、大组车进行速度控制的灵活性,可使勾车入线速度得到提高,因而 The first speed reducer and deceleration combined with the point-connected speed control system in Harbin Station downlink field has achieved good operational results, has many marshalling yards have been adapted to local conditions and applications, useful replacement shoes reducer (such as Loudi Station, etc.), behind the reducer target (such as Xi’an East Railway Station), as well as behind the shunting turnout also target (such as Chengdu East Railway Station). Among them, the Xi’an East Point-point speed control system, due to the target behind the retarder for some distance, one is to increase the slippery hook car, especially difficult to drive, a large group of vehicles for speed control flexibility allows the hook car Into the line speed is improved, thus
