Trains wait until next arrives at station

[lawton27]

I've found a way to have trains wait at a station and continue loading (which will of course up station rating) until another train arrives then leaves with whatever cargo it has loaded, here I've got a simple screen-shot of it and attached save, it wont be useful on large networks as the trains are not ordered to go to the destination it simply must be the only way to go before they can return to the loading station, It will work with any number of trains, which can be changed depending on the route length, my example is simple and uses 2 trains, it wont work with 3 trains properly unless you double up the track to the destination then it would be fine. I'm sure someone can make something even more efficient than this though!
