One of the main advantages of running garden trains in your back yard is that it brings your railroad into full view for all of your family and guests to see without it being hidden away in an attic or basement.

Another advantage is that your whole family can be involved in helping you build and operate it. Some members will like doing the construction. Others will like placing and nurturing the plants. Everyone can help with the cleaning and maintenance; and more importantly, everyone can enjoy it together. The first thing to do is to determine the best location on your property to build your garden train layout. One of the best places is near your back patio where the railroad is easily visible and can be a topic of conversation. Or it could be located in a central courtyard that is present in many homes these days. It can greatly enhance your rock garden or your terrace as well. You could have track going around the pool or lining the front of your flowerbeds. Also, a garden railroad would be a great addition to a greenhouse.
