Include the following types:(1) check value car, for the railway Vehicles weighing, the actual track is a kind of moving in large weights;(2) Power generation car, the car has a small power station, they can always call on the railway line on the power supply;(3) gauge inspection vehicles, for inspection and verification of railway bridges, tunnels and other large buildings close to the limits in order to determine the safety of vehicles;(4) test cars were equipped with test equipment, used to measure and record rolling stock and railway line performance parameters;( 5) The rescue vehicles, for the train accident occurs, clear the line obstructions and incidents from re-rolling stock;(6) LTL office vehicles for the LTL freight train crew members, escort personnel work and rest;(7) Ballast cars transport and shop for the construction of lines unloading ballast;(8) long rail vehicles for the transport of long rail or recycle that old rail;(9) snow vehicles, clear the rail line, the snow outside.

包括以下几种类型：（1）检衡车，供铁路车辆称重用，实际是一种可在轨道上移动的大砝码；（2）发电车，车内设有小型电站，可随时调用于铁路线路上供电；（3）限界检查车，用于检查和核对铁路桥梁、隧道等大型建筑物的接近限界，以确定车辆通过的安全性；（4）试验车，车上装有试验设备，用于测量和记录机车车辆和铁路线路的性能参数；（5）救援车，用于列车运行发生事故时，清除线路障碍物和起复事故机车车辆；（6）零担办公车，供零担货物列车乘务人员、押运人员工作和休息；（7）石碴车，用于修建线路运送和铺卸石碴；（8）长钢轨车，用于载运长钢轨或回收旧钢轨；（9）除雪车，清除线路钢轨内、外侧积雪。

Railway private sidings refer to the branch railway lines which are administered by enterprises or other units and are connected to a State railway line or any other railway line.

铁路专用线是指由企业或者其他单位管理的与国家铁路或者其他铁路线路接轨的岔线。

Based on analyzing the algorithms of Delaunay triangulation creation in domestic and abroad, in view of the situation of building DTM and the need of realizing railway 3D visual design, a divide-and-conquer algorithm to build DTM is presented, the algorithm use square grids to manage disordered points, to form triangular meshes in grids, DTM can be obtained by merging the triangular meshes, so that the work of sorting of the disordered points before building DTM is reduced greatly; moreover, the algorithm utilize subarea to control the vertices of convex hull so that the range which support points locate in can be predefined when searching support points, the workload of searching support points can be reduced and the speed of merging two triangulations is raised.

在分析了国内外构建DTM算法的基础上，针对DTM算法的现状及铁路线路三维可视化设计的需要，创立了一种构建DTM的分治算法。算法引入方格网管理离散点数据，在格中构建三角网，然后再将这些三角网合并形成DTM，极大地减少了构网前对所有参加构网的离散点进行排序的工作量。此外，通过对凸包顶点数据进行分区管理，在搜寻凸包支撑线时，能预先确定出支撑点的范围，减少了搜索工作量，提高了三角网的合并速度。
