O Scale Model Trains at MPM Hobbies
O Scale (1:48 ratio in the United States) is one of the oldest and most celebrated model railroad scales, prized for its large size, fine detail, and broad manufacturer support. Whether you are building your first layout or expanding an established collection, this department covers every category you need — from motive power to finished scenery. Use the category menu above to explore each section.
Locomotives
Locomotives are the centerpiece of any O Scale layout. Browse our O Scale Locomotives category for diesel and steam prototypes across a range of road names and eras. Leading manufacturers in this scale — including MTH Electric Trains — are known for sound-equipped, highly detailed models suited to both operators and collectors.
Monorail
O Scale monorail systems occupy a unique niche in the hobby, blending mid-century transit history with tinplate tradition. Explore our O Scale Monorail category for sets and components that appeal to collectors and operators alike. These systems are a distinctive addition to any O Scale display or layout.
