I can also recommend Nicholas Smith trains. I have a small outdoor loop and siding in front of my house in the Poconos. It’s held up well for the past four or five years. I leave the track out (it’s been ballasted), and bring the trains, buildings and electrical stuff in for the winter). It’s great sitting out on a warm summer night and just enjoy the running trains. During harsh weather and winter, I have an O gauge layout in the basement.
