I think that if you delete only the rail line drawing after LT conversion, you can make it look like a car highway.
Since it was made for reference only, we do not consider the correct height or track width for the building.
LT変換後にレール線画だけ削除すれば車の高速道路っぽくも出来ると思います
あくまで参考程度で作ったので建造物的に正しい高さや線路幅は考えておりません
