MTH (O)

The MTH Premier line offers the highest level of O scale realism. This brand serves scale modelers who demand exact 1/48 proportions. Every Premier model replicates the precise dimensions of the original prototype. These models feature many separately applied details like intricate piping and legible builder’s plates. MTH uses die-cast metal for locomotive boilers and chassis. This construction provides superior traction and a heavy, realistic feel on the tracks.

This line showcases MTH’s most advanced technology. Most Premier locomotives include Proto-Sound 3.0 for realistic digital sound recorded from actual engines. These models also feature synchronized puffing smoke and remote-controlled couplers. Premier engines require wider curves, such as O-42 or O-72, because they are true scale replicas. This allows large steam engines and modern diesels to operate with a realistic overhang. The Premier brand provides the essential tools for a high-performance, museum-quality layout.
