Now that we can see how much room is needed for our tunnel, we can design the town. We bought 3 ready made buildings for this step: a station, a house, and a freight company. Your choice of buildings may be different. Our goal here is simply to show you how to do things.
After the buildings are in the places you want them, draw in the streets. Use a permanent marker for this. All our products are water based and non permanent markers will bleed.
