The Object Data value is the road or track that the convoy or train is attached to. The drop-down next to the Object Data box in the object properties will have a list of all tracks, roads, and rivers that have already been added to the terrain. Simply select the correct entry from this list and the Object Data value will be set.
How do I put Trains on tracks and make them run back&forth
They don't really run back and forth, they just travel until they reach the end of the track and then respawn to the begining of the track. So if your train was to run on track 0 then make sure all the Object Data values of the trains are set to 0
If the Source is a Depot, the train, convoy, or barge must be owned by that Depot number. If the Source is a Station, the train, convoy, or barge must be owned by the country that owns the Station.
Also I cant seem to be able to add feild guns (the 20mm 30mm and 37mm I cant get to work) I assigne them to a feild and set their "class" as Ground Gun.
If your "CAN COLLIDE" box is NOT checked then these guns won't fire.
and is there anything I should know about adding Citys, or other things like Barns and what they do etc.?
Check out the Strategic system for some understanding.

These will effect strat
