O Scale

O Scale Model Trains & Model Railroad Supplies

Enjoy model railroading in a larger, visually substantial format with O Scale model trains and supplies from MegaHobby. O Scale gives locomotives, train cars, structures, vehicles and figures a strong physical presence, making the scale appealing to railroaders who enjoy easily visible detail and substantial trains.

The larger size can make individual models impressive display pieces while also providing plenty of room for detailed railroad scenes. O Scale layouts can range from straightforward train-running setups to developed miniature environments with structures, people, vehicles and scenery.

Build an O Scale Model Railroad

A successful railroad begins with the type of experience you want from the layout. Some modelers emphasize train operation and collecting, while others develop detailed scenery and miniature environments around the railroad.
