Question

I've got 2 artic shelfs, one cargo shelf, one coast shelf, 2 police shelfs, one city emergency shelf, my train track, a police loading station for the new police train, my orrient express and my 2 planes. But its a little cramped, about 4 and a half train tracks, so i cabt display the train completely and its only 2 waggons. Another problem is where to store the planes, i like them but i dont have a good place except on my wardrobe. Wich shelfes are good for displaying trains and others ? ...
