While there are many things to include when creating a model train layout in your home, you will want to make sure you have everything you need prior to getting started.  The first thing to make sure you have available is a large enough space to create your first layout and also to expand at a later date.  You will need to have all of the necessary layout equipment, from trains, controllers, scenery, buildings, and any other embellishments you may want to include.  Once the layout is ready to go, you will want to buy model trains that will complete the entire look of your layout.
