How to set realistic orders?

[boom_box]

I wanted to set up a bus or train order route like this. But I'm still new to OpenTTD.

Station A > Station B > Station C > Station D then turns around from Station D > Station C > Station B > Station A.

So basically, it gets passengers/mails from Station A, unload it Station B, get passengers/mail from Station B for Station C.
And goes on the other stations.

And also, how can I make the trains to turn and not to go beyond the station platform after loading passengers?
The only I can do is that I make station buffers or train depot at the ends of each station but its not realistic for stations with drive thru set-up.

As for your orders question: just have the train stop everywhere. It'll automatically load and unload if you don't order it to do anything else there. For a single line where the train has to go through the stations you can even get away with giving orders to go to the line ends when you use 'normal goto orders' (i.e. NOT goto non-stop).

In the difficulty settings you find "train reversing". Set it to "end of line and at stations".

So basically for now, What I did was that I don't have problems makings stops in Station A to D but for Station D to A, it just simply passing all stations B and C.
Unless I manually added the stations on orders for the return route?

Your current orders are probably along the line of "go non-stop to A" and "go non-stop to D". Then it will skip everything inbetween.
Change the order to "goto A" and "goto D" and then the train will also stop in B and C.

Most fail-safe of course is assigning all stations to the train's orders. That's what I do, as it prevents possible problems later on if you change your train network so that there is a shorter route between A and D that doesn't lead via B and C.

I agree with FooBar, the most 'robust' solution is to simply put each stop in ther order list:

A
B
C
D
C
B
