2. What is the operational efficiency rationale?Reduces fleet size, maintenance costs, and operational complexity by performing dual roles
3. Why was the road switcher created?Railroads wanted one engine that could replace separate big engines for long trips and smaller engines for yard work, cutting costs and making operations simpler.
4. How does a road switcher stay safe and fast?It has strong wheels (trucks) that can go fast, special bearings that reduce friction, and a cab that lets the driver see in all directions for tight yard moves.

Yard Switching: The process of classifying, assembling, and disassembling trains within a railroad yard.
Interchange Service: Rail operations where locomotives or cars move between different railroad companies' lines.
Frictionless Roller Bearings: Advanced bearings that significantly reduce rotational friction compared to older plain bearings, enhancing efficiency and reducing wear.
