Review PROTO Ho Walthers Sp Inch Black Widow Emd Sd9 Diesel #5371 Dcc And Sound

The **Walthers Proto 2000 EMD SD9 Diesel (5371) HO Scale Model (Part No. 920-41712)** is a meticulously crafted replica of the iconic EMD SD9 locomotive, a workhorse of American railroading that dominated freight service in the mid-20th century. This model captures the raw power and industrial elegance of the original, offering an authentic representation of the SD9 s robust design, which was a staple on railroads like the Southern Pacific, Union Pacific, and others during its prime. The Proto 2000 series is renowned for its high level of detail, blending historical accuracy with modern modeling techniques to deliver a piece that stands out on any layout. The SD9 s distinctive long hood, sloping nose, and classic EMD styling are faithfully reproduced, complete with precise panel lines, rivet details, and weathering effects that evoke the locomotive s well-used yet enduring presence on the rails. The model features a **sound system** that brings the SD9 to life, with realistic diesel engine noises, horn sounds, and bell tones that enhance immersion during operation. The sound system is seamlessly integrated, ensuring smooth performance without compromising the model s structural integrity or aesthetic appeal.

Under the hood, the Proto 2000 SD9 is equipped with **DCC-ready electronics**, making it compatible with modern control systems while retaining the option for traditional DC operation. The motor and gearing are tuned for smooth acceleration and realistic speed curves, allowing the model to handle the demands of detailed layouts with ease. The underframe is designed with attention to historical accuracy, featuring accurate coupling heights, functional handrails, and a detailed ladder system that complements the locomotive s industrial aesthetic. The model s **paint scheme** is versatile, offering a clean, factory-fresh appearance that can be easily customized with weathering, decals, or additional detailing to match specific railroad liveries, such as the Southern Pacific s iconic black-and-gold or the Union Pacific s distinctive red-and-white. Whether displayed as a standalone centerpiece or integrated into a larger railroading scene, this SD9 exudes the timeless charm of mid-century diesel power, making it a prized addition for enthusiasts who appreciate both authenticity and performance.

### **Pros and Cons of buying a Proto 2000 EMD SD9 (5371) Sound Kit (920-41712) for HO Scale**

#### **Pros:**

1. **High-Quality Sound System** The Proto 2000 sound kit is widely regarded as one of the best in the HO scale market, offering realistic diesel engine sounds, horn tones, and bell operation. The kit includes a high-fidelity sound processor with multiple sound layers for different engine conditions (idle, cruise, acceleration, etc.).

2. **Compatibility with Many Locomotives** This sound kit is designed to work with a variety of EMD SD9/SD7/SD8 models, including those from Walthers, Atlas, and others. It can be adapted to fit different chassis types, making it a versatile upgrade option.

3. **Easy Installation** The Proto 2000 system is known for its straightforward wiring and mounting process. The sound processor is compact, and the wiring harness is well-organized, reducing installation time compared to some other sound kits.

4. **DCC and DC Compatibility** The kit supports both DCC and DC operation, making it suitable for both traditional and modern control systems. It includes a DCC decoder-compatible version, which is a major advantage for digital modelers.

5. **Realistic Sound Programming** The sound files are meticulously recorded from real diesel locomotives, providing authentic engine noises, exhaust pulses, and dynamic horn sounds. The kit allows for customization of sound parameters (volume, pitch, etc.) via the included software.

6. **Durability and Reliability** Proto 2000 components are built to last, with high-quality wiring and connectors that minimize the risk of shorts or failures. Many users report long-term reliability with minimal maintenance.

7. **Positive Community Reputation** The Proto 2000 sound kit has a strong following among model railroaders, with numerous positive reviews highlighting its performance and ease of use. This builds confidence in its quality.

#### **Cons:**

1. **Cost** The Proto 2000 sound kit is not inexpensive, especially when factoring in the cost of the locomotive body if you re starting from scratch. For a pre-built locomotive like the Walthers SD9, the upgrade cost can still be significant, particularly if additional modifications (e.g., new lights, improved wheels) are needed.

2. **Potential for Overkill** If you re a casual modeler or only run a few locomotives, the investment in a high-end sound kit may feel excessive. For smaller layouts or limited use, a more budget-friendly sound solution (e.g., a simpler sound module or even a pre-sound-equipped locomotive) might suffice.

3. **Installation Complexity for Beginners** While the Proto 2000 system is relatively straightforward, it still requires some electrical knowledge and patience. Beginners may find wiring the sound processor, motors, and lights challenging, especially if adapting an existing locomotive. Additional tools (soldering iron, wire strippers, etc.) may be needed.

4. **Space Constraints** The sound processor and wiring harness take up space inside the locomotive. If your model has a tight chassis or limited interior room, installation may require creative routing or modifications to accommodate everything neatly.

5. **Learning Curve for Sound Customization** The included software for programming the sound kit has a learning curve. Users must understand how to adjust parameters like sound volume, pitch, and timing to achieve the desired realism. Some may find the process frustrating if they re not tech-savvy.

6. **Potential for Compatibility Issues** While the Proto 2000 kit is versatile, there s always a risk of compatibility issues, especially if adapting it to a non-standard locomotive. For example, some older or non-DCC models may require additional modifications to work seamlessly.

7. **Ongoing Maintenance** Like any electronic component, the sound processor and wiring are subject to wear over time. Users should periodically check connections, especially if the locomotive is frequently moved or exposed to moisture.

### **Conclusion:**

The Proto 2000 EMD SD9 sound kit (920-41712) is one of the best sound upgrades available for HO scale diesel locomotives. It delivers exceptional realism, ease of installation, and compatibility with a wide range of models. For serious model railroaders who prioritize sound quality and are willing to invest time and money, this kit is an excellent choice.

However, it is not without drawbacks. The cost can be prohibitive for some, and the installation may be daunting for beginners. Additionally, if you re only running a few locomotives or have limited space, the benefits may not justify the expense. For those who are committed to creating an immersive, high-fidelity model railroad experience, the Proto 2000 sound kit is highly recommended. For others, a more budget-friendly alternative might be a better fit.

### **Recommendation:**

- **Buy it if:** You re a dedicated modeler who values realistic sound, have the budget and technical ability to install it, and plan to use the locomotive extensively. It s particularly worthwhile if you re running a digital layout with DCC.

- **Consider alternatives if:** You re on a tight budget, have limited experience with electronics, or only run a few locomotives. In that case, explore pre-sound-equipped locomotives, simpler sound modules, or other mid-range sound kits like the Bachmann Sound System or the more affordable Proto 2000 Lite.

- **For the Walthers SD9 specifically:** If you re happy with the body but want to upgrade the sound, the Proto 2000 kit is a fantastic choice. However, if you re also looking to improve other aspects (e.g., wheels, lights, or motor), factor those costs into your decision.
