OK, I’ve done a preliminary study for the Town section of the Display using the MILS standard. The street is brick built and laying on its side. This allows the sidewalk to be one plate/tile higher, creating a curb. The sidewalk is primarily 2×2 tiles on top of 2×4 bricks, although a brick build sidewalk (like the street) would also work (so long as a row of plates was attcahed to the baseplate thus raising the sidewalk again 1 plate higher than the street to make the curb). I also added some “snow” piled up against the building.
Overall, I think this type of layout will work well. I can definitely provide two parallel brick built streets connected by a cross street (I’m thinking in the shape of an “F”) and also the buildings for the downtown. I also want to do a separate row of small residential houses which would be the pick up spot for the Polar Express.
