Specific embodiment
For driving emulates, most important information is the location information of Wayside signal and by signal out of the station in fact
The station circle of machine mark（For showing station and its attached station track, track switch）.There are these information, we in fact can use dynamic
The mode of state modeling is placed Wayside signal in suitable position automatically, shows that station and its attached station track, track switch and station are attached
Belong to building.
The location information of Wayside signal is a numerical value, can at any time be read during emulation of driving a vehicle.
The relative distance of front signal machine and the attribute of front signal machine can be shown in LKJ screen displays at any time（By semaphore still into
Exit signal）.Our softwares can accomplish the semaphore position letter in 3D views and analogue simulation unit in actual motion
The accurate matching of breath.There is deviation needing the practical parking stall of rehearsal locomotive and semaphore position（Advanced or lag）Situation when, we
Model can also change at any time front signal machine appearance position, simulation such case true to nature.
When carrying out railways train operation modeling, the attribute of incoming semator in 3D modeling software：Home signal, outbound letter
It is number machine, route signal, auxiliary by semaphore, obstruction signal, distant signal, shunting signal, hump signal, hump
