The track plan is in oval shape with two track routes. The outer line is suitable for continuous run of express passenger trains. The inner line is dedicated for freight trains, which are passing from the one module to another, where the industries / cargo zones are located. The two lines are connected with a single crossover on the right module, but the main idea is they to be used independently. The center module with the river can be removed and the layout can be assembled with the left and right main modules, depending of your own IVAR setup.
