Let see if I add a gold mine to the layout I will have to get some gold ore cars to transport the ore to a new gold refinery I built, then I can use my gold bullion car to transfer the gold bullion to the newly built gold mint or Fort Knox. For more action I could use some gold coin dumping cars to transfer the coins for distribution. This is where the plan falls down but I like it as I am always looking for jobs for my rail road.
