Getting started in model train building requires that you make a decision right off the bat as to what model train scale that you are going to build your collection around. This is going to decide how much space you will need for building and the variety of accessories that you have to choose from.

The smallest of all of the model train scales is the N scale. These are more like matchbox scale as they are only 3″ long. If you are challenged for space, you are will not find a better size to work with. You can still have a pretty extravagant set up, it will just be done with miniatures.

For the most part, HO scale is what you are going to see prominently displayed at most hobby shops. This is because most of the companies that sell these supplies concentrate the bulk of their product in this level. At only 6 inches big, they are the perfect size to create a very attractive display and offer the most variety.

O scale cars are synonymous with one manufacturer, Lionel Trains, who has been manufacturing this size train since 1900. Originally designed to be a window display for department stores, it quickly caught on to becoming a household accessory, particularly around Christmas time. These cars are around 9″ long and are the most popular choice for those incredible under the tree displays.

G scale is the “Big Daddy” of model railroading. G or “Garden” scale trains are built particularly for outdoor use. The cars are 16″ long and 6″ high, making these the only choice for an outdoor display where room is not a factor. They can be routed through the yard in a variety of ways to make your neighbors green with envy.

Now the reason we go over all of this is to once again emphasize that size is very important when you are selecting your train set. Not only is it about the size of the train, but the space required for the train to get around the track properly. The larger the train, the more space it needs to make a turn. This affect the amount of space you have to allow for the diameter of your loop.

For one final concern is the power that is needed to get your train around the track. You can rest easy when you are selecting your set because there is no danger to the little ones. They usually run off of the 110 volt outlet that you will already have and will require no alterations. This means a lot of safe and happy train operating down in the basement with dad and the kids!
