“拔萝卜打牌不盖被子”火车各种鸣拔萝卜打牌不盖被子笛声都是在“说”啥,你知道吗?

  随着拔萝卜打牌不盖被子春节临近,越来越多人陆续踏拔萝卜打牌不盖被子上返乡的旅途。记忆里,列车的鸣笛声,就像是回家的号角,开启了一段段团圆的旅程。有不少朋友发现,现如今,我们乘坐高铁时,基本听不到鸣笛声音了。那么,火车都在什么情况下鸣笛,不同鸣笛声音组合代表什么意思?今天的《春运涨知识 高铁知多少》,我们来说说火车的鸣笛声。

  火车鸣笛有哪些讲究?

  火车是怎么鸣笛的?

  在各型机车以及高铁列车驾驶室,都有风笛和电笛两种鸣笛按钮,司机脚下还有鸣笛踏板,火车司机只需按下按钮或踏下踏板,就会发出鸣笛声,并通过不同的组合表达不同的意义。

  火车鸣笛有什么讲究?

  国铁太原局太原机务段指导司机 赵卓明:铁路对于火车鸣笛有严格规定,长声3秒、短声1秒、间隔1秒,需要重复鸣示时,需间隔5秒以上。通过不同组合,形成13种鸣笛方式,表示不同的含义。常用的一长声是注意信号,表示接近鸣笛标或有行人,要引起人们注意。一长三短声是警报信号,表示发现有危及行车安全的不良处所,要减速运行;如果连续短声鸣笛,表拔萝卜打牌不盖被子示发现邻线有故障,向邻线列车发出紧急停车信号。

  为啥很少听到高铁列车鸣笛?

  为了减少鸣笛对铁路沿线人们生活的干扰,铁路部门对鸣笛区域进行了限制,很多居民聚居区都纳入限制鸣笛区域。特别是伴随着铁路通信方式的发展,很多以前需要鸣笛的事项都可以通过通信设备联系。

  国铁太原局太原机务段动车运用车间主任 申旭杰:列车在运行途中,除遇危及人身、行车安全和联系不通、通信设备故障等特殊情况外,司机一般不再鸣笛,即使鸣笛也会优先使用电笛或低音风笛,减少噪声污染。所以现在大家很少听到高铁鸣笛声。
