You have the platform all set up, along with several dozen feet of track. Now all you need are the right O Scale trains to make your train set perfect. Whether you are creating a special Christmas display or enjoy trains as a hobby year-round, you can find the trains and accessories you want among the vast inventory available on eBay. Your holiday train display is not the same without O Scale model train buildings such as a train station, houses, and businesses such as a bank and grocery store that you decorate for the holidays. When the train pulls into the station, having people to get on and off your O Scale passenger trains completes the display and makes operating the train set that much more enjoyable. O Scale trains are small enough that you can create an impressive display in a relatively small space, but large enough that you can still enjoy the details of the trains themselves. For many train aficionados, O Scale is the ideal size.
