列车开头的字母都分别都代表什么呢
（1）点到点一站直达特快列车,车次前冠以字母“Z”,（读“直”音）。车次范围：Z1——Z998。如北京—上海Z1/2次、北京—杭州的Z9/10次、北京—苏州的Z85/6次等，但这些列车是一站直达，都不在济南站停车。
（2）
跨局特快旅客列车，车次前冠以字母“T”，（读“特”音）。车次范围：T1——T998。如济南—北京的T36次，济南—上海的T105次，青岛—北京的T26次等。
（3）
跨局快速旅客列车，车次前冠以字母“K”，（读“快”音）。车次范围：K1——K998。如济南—重庆的K15/8/5次、青岛—福州的的K70/67次等。
（4）局管内快速旅客列车，车次前均冠以字母“N”，（读“内”音）。济南局管内快速旅客列车车次范围为：N451——N500。如济南—青岛的N469次、济南—日照的N477次等。
（5）临时开行的旅客列车，车次前冠以字母“L”，（读“临”音）。
（6）
旅游列车，车次前冠以字母“Y”（读“游”音）。
（7）普通旅客列车，车次前“不冠以字母”。
*在旅行中，人们往往对两列对开的列车车次的运行方向搞不清楚，我们可以这样来区分列车的运行方向：凡是车次的编号是双数（偶数）的，那就是向北京方向去的，称为“上行列车”，如T36次、
K206次等等；凡是车次的编号是单数（奇数）的，那就是与北京方向背离运行的列车，称为“下行列车”，如T35次、K205次等等。
*有的同趟列车会有4个编号，那是因为中途列车方向有了改变的缘故。如青岛开往兰州的旅客快车，在青岛发车时车次编号是K172/3次，从兰州返回时则是K174/1次。这表示从青岛到济南区段行车是朝北京方向，而从济南往兰州行车是背离北京方向。搞清列车的车次编号，乘车、购票、接送客人、转车就不会搞错了。
