[Thomas the tank engine] how does this island of sodoor maintain its economy and support a fleet of steam engines which aren't efficient in the modern day?

Does the driver of the engines have any control over the destination or is it all the engine themselves? The engines seem to just follow their own whimsical fansies and disobeying the fat controller and sir topham hat. How is this viable economically?
