These heaters prevent engine damage from freezing and reduce wear during cold starts. The distinctive heater vents are visible exterior details on locomotives equipped with these systems, making them important for accurate modeling of cold-weather railroad operations. With two vents in this set, you can detail multiple locomotives or add proper vents to both ends of a single unit.\u003c\/p\u003e\u003ch3\u003eWhy Choose CMR Detail Parts?\u003c\/h3\u003e\u003cp\u003eCMR specializes in producing fine-scale detail accessories that bring realism to model railroads.
