Maybe you could build an Icelandic route, the first of its kind. It could tell the story of how the we developed our first rail system, the passenger line from from Reykjavik to the peninsula towns of Grindavik and Keflavik first opened in 2014. With the economic recovery of Mother Iceland (and the rest of the world), trade boomed, requiring the devlopment of a rail infrastructure not just from the capital to commuting towns, but a circular system round the circumference of the whole island. The scenery and landscape is a perfect Trainz modelling project. Two pathetic tourist routes were made in the north, climbing steep narrowguage lines into the mountains. In the real world, heavy industry devleoped around the vastly overpopulated cities of Hofn and Olafsvik, huge rail yards were set up to shift goods from industry to port where they are sent to the rest of the world. Iceland, the top of the world. The perfect strategic location, supplying both the Americas and Europe. The country's government was heavly criticised in the 2030's for putting industrial economic development ahead of environmental concerns. Much of icelands beautiful wilderness areas were scarred by ugly modern, concrete and steel rail lines. Pollution incidents occured, wildlife suffered, but the railroads triumphed. The locomotives, designed and developed in Iceland were a fusion of American power, British charm, European efficiency and Japanese awsomeness. Iceland iteself experienced over 25 years what Japan experienced over 100. Massive economic development, without the earthquakes. It's history of neutrality led it to trade successes with both the Americans/Europeans as well as the Russians and Chinese. Iceland even won the Eurovision song contest two years running and hosted both the soccer world cup and the winter olympics in 2034.
Do it!
