Review ATHEARN Undecorated Diesel Powered Locomotive Kit

The **Athearn 4655 Undecorated GP38-2 Diesel Locomotive Kit** is a meticulously crafted, high-detail model kit that offers an exceptional building experience for both novice and seasoned hobbyists alike. Designed to replicate the iconic General Motors EMD GP38-2, one of the most recognizable and widely used road-switcher locomotives in North American railroading history, this kit captures the essence of mid-20th-century diesel power with remarkable precision. The GP38-2, introduced in the late 1960s, was a robust and versatile locomotive, known for its reliability and adaptability across freight, passenger, and industrial service, making it a staple on countless railroads. Athearn s undecorated version of this classic model provides a blank canvas for customization, allowing builders to paint and detail their locomotive to represent any specific road, era, or even a fictional railroad, limited only by their imagination.

This kit is constructed from high-quality, durable materials, including precision-cut metal chassis components and finely detailed plastic parts that require minimal sanding or finishing. The body shell is molded with exceptional attention to surface texture, including subtle panel lines, rivet details, and weathering cues that evoke the look of an authentic locomotive after years of service. The underframe features a robust, articulated design with accurately proportioned components, including the iconic EMD 645 prime mover, detailed exhaust stacks, and a realistic radiator grille. The kit includes a fully assembled and operational chassis with a functional DC motor, allowing for smooth, realistic movement once assembled. The wheelset assembly is designed with precision, featuring accurate wheel profiles and a balanced drive system that ensures long-lasting performance.

For those seeking to delve deeper into the world of model railroading, the GP38-2 kit offers a wealth of customization options. The undecorated nature of the model means builders can choose from a vast array of paint schemes, from classic railroad liveries like Union Pacific s silver and black or Norfolk Southern s red and gray, to more obscure or even custom designs. The kit s detailed surface features, such as the textured paintable panels and raised details like the headlight bezels and coupling hooks, allow for realistic weathering and aging effects, enhancing the authenticity of the finished model. Additionally, the kit s compatibility with Athearn s extensive line of accessories, including sound systems, lighting kits, and detailed couplers, further elevates the realism and operational capabilities of the locomotive.

Beyond its aesthetic and functional qualities, the Athearn 4655 GP38-2 kit is a testament to the brand s commitment to quality and innovation in model railroading. Whether used as a centerpiece on a mainline layout or as part of a dynamic freight operation, this locomotive brings a sense of nostalgia and authenticity to any railroading scene. The kit s undecorated design ensures that each builder s creation will be uniquely their own, reflecting their personal style and attention to detail. For enthusiasts who appreciate the art of model building as much as the end result, the GP38-2 offers a rewarding and satisfying project that captures the spirit of America s golden age of diesel railroading.

**Pros and Cons of buying a Athearn 4655 Undecorated GP38-2 Diesel Locomotive Kit**

The Athearn 4655 undecored GP38-2 is a popular model kit for hobbyists, offering a balance of realism and buildability. Below is a detailed breakdown of its advantages and disadvantages.

### **Pros**

1. **High-Quality Construction**

The kit is well-engineered with durable materials, including die-cast metal parts for key components like the frame, wheels, and cab. This ensures longevity and a sturdy finished model.

2. **Undecorated Design**

The absence of pre-applied decals or paint allows for complete customization. This is ideal for modelers who want to paint their own locomotives, apply specific railroads, or experiment with different color schemes.

3. **Accurate Scale and Proportions**

Athearn is known for producing models that closely resemble real-world GP38-2 locomotives in terms of scale (1:87 or N-scale) and detail. The proportions are well-balanced, making it visually appealing even without additional modifications.

4. **Comprehensive Component Set**

The kit includes all necessary parts for assembly, including detailed interior components (cab, controls, lighting), exterior panels, and even some weathering-ready features like rivets and bolts.

5. **Good Value for the Price**

Compared to other high-detail model kits, the Athearn GP38-2 offers excellent value. It strikes a balance between affordability and quality, making it accessible for both beginners and experienced modelers.

6. **Flexibility for Weathering and Detailing**

Since the kit is undecorated, modelers can apply their own weathering techniques, such as rust, dirt, or wear patterns, to enhance realism. This is particularly appealing to those who enjoy post-assembly detailing.

7. **Compatibility with Accessories**

The kit is designed to integrate seamlessly with other Athearn or third-party accessories, such as couplers, sound systems, or lighting modules, expanding its functionality on a layout.

8. **Beginner-Friendly Yet Challenging for Advanced Builders**

While the kit is straightforward enough for beginners to assemble, it also offers enough complexity for advanced modelers to incorporate additional details, such as custom-built interiors or enhanced mechanical components.

---

### **Cons**

1. **Limited Pre-Painted or Decal Options**

Since the kit is undecorated, modelers must handle painting and decal application themselves. Those who prefer a ready-to-run (RTR) or semi-detailed model may find this a drawback.

2. **Time-Consuming Assembly**

The GP38-2 is not a "quick build" kit. It requires patience, especially for those new to model railroading, as it involves careful assembly of multiple parts, including the frame, wheels, and cab.

3. **Potential for Assembly Errors**

Like any complex kit, mistakes during assembly such as misaligned parts or improperly secured components can affect the model s appearance or functionality. Careful reading of instructions is essential.

4. **Limited Customization Without Additional Tools**

While the kit is detailed, some modelers may want to add further customization (e.g., custom-built interior, enhanced lighting, or dynamic features). This may require purchasing additional tools or parts, increasing the overall cost.

5. **Weathering and Detailing Require Skill**

Achieving realistic weathering effects (e.g., rust, grime, or wear) can be challenging for beginners. Poorly executed weathering may detract from the model s appearance rather than enhance it.

6. **Potential for Overcomplication**

For very new modelers, the GP38-2 s complexity might feel overwhelming. Simpler kits or RTR models may be a better starting point before tackling a detailed undecorated kit.

---

### **Conclusion and Recommendation**

The **Athearn 4655 undecorated GP38-2** is an excellent choice for modelers who prioritize customization, realism, and a satisfying build experience. Its high-quality construction, accurate detailing, and flexibility make it a standout kit for those willing to invest time in assembly and finishing.

- **Buy it if:** You enjoy painting, weathering, and customizing models; you have some experience with model railroading; or you want a durable, detailed locomotive that can be personalized to match a specific railroad or era.

- **Avoid it if:** You prefer ready-to-run models with minimal assembly; you lack patience for detailed builds; or you re a complete beginner looking for a simpler introduction to model railroading.

For most hobbyists with moderate experience, the GP38-2 offers an ideal blend of challenge and reward. Those new to model railroading might benefit from starting with a simpler kit before tackling this one. Ultimately, the kit s value lies in its ability to serve as both a functional model and a creative outlet for customization.
