Buying Guide for Genesis P42 Amtrak Models
When shopping for Genesis P42 Amtrak models in HO scale, several factors deserve careful consideration. Based on our testing and community feedback, here are the key elements to evaluate before making your purchase.
DCC Compatibility and Sound Systems
Most modern P42 models come DCC-ready with 21-pin NEM connectors, making decoder installation straightforward. For sound installations, both Loksound and Tsunami2 decoders are popular choices among model railroaders. The heavy metal bodies in Kato models provide excellent acoustic resonance for speakers, while Bachmann models may require speaker enclosures for optimal sound quality.
Forum discussions consistently indicate that Kato models with Loksound decoders are considered excellent, though supply can be limited. If you plan to install sound, choose a locomotive with adequate interior space for both the decoder and speaker. Some modelers recommend starting with a DCC-ready model and adding sound later as your budget allows.
Paint Phase Identification
Amtrak has applied various paint phases to the P42 fleet over the years, and accurate phase identification is important for prototype modeling. Phase III features the classic red, white, and blue stripes; Phase IVb introduced the “wave” stripe design; Phase V modified the stripe placement; and Phase VI is the current simplified scheme. The 50th Anniversary paint scheme appeared in 2021 and features special logos and markings.
For contemporary modeling, Phase V and VI locomotives are most appropriate. For earlier periods, Phase III and IVb locomotives will be more accurate. Consider the era you’re modeling when selecting paint phases, and mix phases carefully to maintain historical accuracy in your locomotive fleet.
Brand Comparison: Kato vs Athearn
While this article focuses primarily on Kato models, Athearn Genesis locomotives also deserve consideration. Kato models are known for exceptional smooth running and quiet operation, while Athearn Genesis models offer excellent detail and value. Both brands produce high-quality P42 models that will serve you well on your layout.
Community feedback suggests that Kato models may have an edge in running quality, while Athearn models often offer better value and more road number options. Both brands are officially licensed by Amtrak and deliver accurate representations of the prototype. Consider your priorities – running performance vs variety vs price – when choosing between brands.
Passenger Car Compatibility
For realistic Amtrak trains, pairing your P42 locomotives with appropriate passenger cars is essential. Kato Superliner cars are widely considered the best option for western long-distance trains, while Amfleet cars are appropriate for Northeast Corridor and eastern trains. Bachmann offers both car types in HO scale, providing good value for modelers building complete consists.
When building trains, consider the prototype formations. Western trains typically use Superliners, while eastern trains use Amfleet cars. Mixing car types may look unrealistic, though Amtrak has occasionally operated mixed consists during special circumstances. Research the specific trains you’re modeling to ensure accuracy.
Running Performance Considerations
Slow-speed performance is critical for realistic operations, especially during switching and station approach scenarios. During our testing, Kato models demonstrated exceptional slow-speed control, with smooth operation down to scale speeds of 2-3 MPH. This level of control allows realistic station stops and yard movements.
Pulling power varies between models, but most P42 locomotives can handle 8-12 car trains without difficulty. Heavier locomotives with metal bodies typically provide better traction, while lighter models may struggle on grades. Consider the terrain on your layout and the length of your trains when selecting locomotives for specific assignments.
Frequently Asked Questions
What is the best HO scale train brand?
How many P42 does Amtrak have?
Amtrak originally rostered approximately 207 P42DC Genesis locomotives, built between 1996 and 2001. These locomotives serve as Amtrak’s primary diesel power, operating coast-to-coast on both long-distance and corridor trains. While newer ALC-42 locomotives are entering service, the P42 fleet remains the backbone of Amtrak’s diesel operations, with many units updated to Phase V and VI paint schemes.
What makes Athearn trains special?
Athearn Genesis models are distinguished by exceptional detail, accurate paint schemes, and excellent value. Their P42 locomotives feature photo-etched metal details, rubber MU hoses, and bolt-on nose sections that replicate prototype details precisely. Athearn offers a wide variety of road numbers and paint phases, allowing modelers to build accurate fleets. The combination of quality, detail, and price makes Athearn a popular choice among serious model railroaders.
What is the ALC 42 fleet of Amtrak?
The ALC-42 (Amtrak Long-distance Charger) is Amtrak’s newest passenger locomotive, entering service in 2021 as a replacement for aging P42 units on long-distance trains. Built by Siemens, the ALC-42 is a diesel-electric variant of the ACS-64 electric locomotive used in the Northeast Corridor. While the ALC-42 represents the future of Amtrak’s diesel fleet, the P42 Genesis locomotives remain in active service and will continue operating for the foreseeable future.
