Traffic system of train simulation

[abz89]

hi for all byte's member :D

just want to ask, recently i've tried many of programming language. And as my test application, i want to create a little program that simulating train traffic.

i,e. train go from station A then station B. After that, the train have moving reverse, from B to A

 
train@station A                     B
.=======>>--------------------------.
 
A                           train@station B
.-----------------------------====>>.
 
A                        train@station B moving backward
.--------------------------<<=======.
          ("D" as distance)
 

anybody have an algorithm to implement? :)

thx a lot
