rail api

Hi everybody

I am using the rail api.
well, apart from those difficulties to understanding functions like:

getrailedgedist(num edge)
Description: Returns the total distance of the edge.
Example: getrailedgedist(2);

or understanding why a createrailsequence is not a sequence of rails but actually a sequence of cars, or a function description such as:

createrailpath:
Creates a rail path. Use the return value of this command as the second parameter of the ...


I have got other difficulties.

When I run the simulation, I have no idea where my train is. therefore, I do not know the first parameter of the following function:

createrailpath(startedge, 0, exportyardedge, trainlength + 2);


what would be a solution to this? how shall I call a train to come to the place I need?

Read the thread:

Anthony provides some examples and command list and description. Linwei Xu also provides some examples. These are good for understands rail api commands.

thanks anyway as general comment.
But still my question was something like how to call a train to arrive at certain location without knowing where it is actually.
