Build a locomotive roster around the railroads and trains you enjoy. Athearn Genesis locomotives offer subjects ranging from first-generation Santa Fe F7s to EMD road switchers, modern mainline diesels and Amtrak P42DC passenger locomotives. Road numbers, paint schemes and control configurations are identified in the individual listings.

Choose a railroad, a train and a locomotive
A useful way to build an Athearn Genesis locomotive roster is to begin with the service you want to run. A switching layout can center on a compact MP15AC or GP15, while a railroad with longer passing sidings and through freights may suit GP-series road switchers or six-axle mainline power. Passenger operations call for their own identity: an Amtrak P42DC represents a different train and paint-scheme history from a freight GP38-2.
The range includes railroad subjects such as Union Pacific, Santa Fe, BNSF, Norfolk Southern, Southern Pacific, Burlington Northern, Milwaukee Road and Amtrak, along with shortline, leasing and demonstrator schemes. Specific releases and availability change, but the product titles make the road name and number visible so you can build a roster deliberately.
Examples from the Genesis locomotive selection
Road numbers and locomotive sets
Two models in the same railroad's colors can represent different equipment. A production phase, high-hood body, rebuild designation or road-number detail can matter when matching prototype photographs. Likewise, a single F7A listing and an F7A-B set are different purchases. Review the title, SKU and pack information together before choosing a consist.
Will any HO scale Genesis locomotive fit my layout?
Scale establishes the model's proportions, but curve radius and clearance remain model-specific. Check minimum and recommended radius, especially for long six-axle locomotives and passenger power. Broader curves can also improve the appearance of a locomotive and the cars it pulls.
Match the locomotive to its assignment
A local freight, industrial switching job and long-distance passenger train each call for different motive power. GP-series locomotives and MP15AC switchers suit a range of freight assignments, while larger GE and EMD diesels offer subjects for mainline consists. Amtrak's P42DC provides a distinct choice for passenger operations.
Within a locomotive family, Genesis releases can reproduce different body details, road-number features and paint variations. Use the complete model name and road number to identify the version you want rather than relying on the locomotive family alone.
DC, DCC-ready or factory sound
Choose the electronics configuration that fits your layout and installation plans. Standard DC and DCC-ready versions are listed separately from locomotives supplied with factory-installed DCC and sound. Check the decoder connection and installation requirements on the specific model before selecting an upgrade.
Review minimum operating radius, recommended radius and any stated pack contents before ordering. An F7A-B set contains a different combination of equipment from a single locomotive listing.
