So what I thought is, what if Some One Made a Japanese Industry Set Containing stuff like :
Train Yard (Accepts Steal, Glass And Electronics to make Trains but not needed to make your trains),
Ship Yard (Accepts Steal, Glass and Electronics for Making Sjips, again, not needed for Making your Ships),
Electronics Industry (Accepts Plastic, Copper, Glass to make Electronics)
Farms like Live stock, Rice, Vegies and Fruits, Milk and a Wheat Farm (Makes Cereals and Grain)
Sake Brewery (Needs rice to make Sake Which can be accepted by most towns/cities)
Beer Brewery (Needs Grains to make Beer which again, can be Accepted by most towns/cities)
Natural Gas Power Plant (Needs to Natural Gas to Produce Power which could be use to help make a town/city grow)
Oil Power Plant (Needs to Petrol or Oil to Produce Power which could be use to help make a town/city grow)
Food Processing Plant (Needs an Assortment of things like Milk, Cereals, LiveStock, Vegies, and Fruit to make food)
and also most of the other ECS Industries
BTW I think that the exsisting Japan set trains will need to be modified in order for it to work with this idea, If I knew how I would do it my self but too bad, i dont

I hope that can be done, and if not could some one make an adepter for the Japanese Train set for the ECS Industries or make a Japanese Train Set that Includes ECS in it?
