Welcome to the forums.
Now I'm going to tell you to go away. Not very far away, but go to the Classic Toy Trains forums section of Trains.com. Most of the people here arein N and HO scale. The folks over at CTT forums are more into O scale.
Good luck,
I am new to the model train world and have o gauge Lionel track. can anyone tell me if there is a joiner track to go from o gauge to fast track ?
