These two 4' by 10' layouts are on both sides of a room, connected by a bridge that can be lifted out. The distance between tables depends on your circumstances. Here we have taken our previous layouts and added a second section. The upper layout would probably be serving port industries and ship suppliers. Again, the fan of switching operations and operating loader-type accessories will have a great time.
Now we have changed the bottom layout. You can use the sidings inside the left loop as engine facilities, while the sidings can serve industries or accessories. Those who enjoy operating accessories would be in their element with this layout.
