Review MTH Gauge Santa Fe Emd Diesel Smoke And Protosound Doesnftt Run

The **MTH 20-2145-1 Gauge FE EMD FP-45 Diesel** is a meticulously crafted, high-fidelity model that brings the iconic American locomotive to life with unparalleled realism and attention to detail. Engineered under MTH s renowned Protosound Digital Command Control (DCC) platform, this model delivers an immersive audio experience that captures the raw power and authenticity of an EMD FP-45 diesel, complete with a full complement of **Protosound Digital Sound Effects (NDFTS)**. The FP-45, a robust and versatile freight locomotive built between 1954 and 1960, was a workhorse of North American railroads, and this model faithfully replicates its imposing presence with precise proportions and authentic styling. The **FE (Full Effect) sound system** integrates a **16-channel digital sound engine** that produces lifelike diesel engine noises, including the growl of the prime mover, exhaust pulses, and intricate details like air brake operation, bell sounds, and horn sequences all synchronized with the locomotive s movements. The **NDFTS (No Digital Frictionless Tracks) technology** ensures that the sound remains dynamic and responsive, even on the most challenging track layouts, eliminating the need for additional track-side electronics to achieve realistic audio performance.

Mechanically, this FP-45 is built with MTH s signature **Precision Scale Modeling** standards, featuring a **highly detailed body shell** with accurate panel lines, rivet patterns, and weathering effects that reflect its era. The **metal underframe** provides exceptional durability and stability, while the **five-axle, articulated truck setup** ensures smooth, realistic motion, mimicking the natural flex of a full-scale locomotive. The **DCC-ready motor** delivers consistent, powerful traction, allowing for precise speed control and smooth acceleration, whether pulling a single car or a long freight train. The model s **low-profile design** and **compatible coupling system** make it ideal for both static display and dynamic operation, seamlessly integrating into any HO-scale layout. Whether representing a classic freight hauler on a mainline or a museum piece in a display case, this FP-45 exudes the timeless power and engineering legacy of EMD s legendary diesel era, making it a must-have for serious modelers seeking both authenticity and performance.

### **Pros and Cons of buying a MTH 20-2145-1 Gauge FE EMD FP-45 Diesel (Protosound)**

1. **High-Quality Sound System (Protosound)**

- The Protosound DCS (Digital Command System) provides realistic diesel engine sounds, including exhaust, intake, and detailed articulation. This enhances the realism and immersion for operators and observers alike.

2. **Accurate Scale and Proportions**

- MTH is known for producing models that closely match real-world locomotives in terms of scale, detailing, and proportions. The FP-45 is a well-researched model, making it visually appealing to collectors and operators.

3. **Detailed Interior and Exterior Features**

- The model includes a detailed cab interior with realistic controls, lighting, and even a working bell and horn. Exterior details such as rivets, ladders, and handrails are well-executed, adding to its authenticity.

4. **Compatibility with Digital Command Control (DCC)**

- The locomotive is DCC-compatible, allowing for advanced control options like speed adjustments, lighting effects, and sound programming. This makes it versatile for both static display and operation.

5. **Strong Motor and Performance**

- MTH s motor is robust, providing smooth acceleration and reliable performance on most track layouts, including curves. The FP-45 s power output is suitable for medium to large-scale layouts.

6. **Durability and Build Quality**

- MTH models are generally well-built, with sturdy chassis and components that withstand frequent use. The FP-45 is no exception, offering longevity for enthusiasts.

7. **Collectible and Investment Potential**

- As a well-regarded model from a reputable manufacturer, the FP-45 holds value over time. It appeals to both hobbyists and collectors, potentially increasing in worth if demand remains strong.

---

1. **Higher Price Point**

- The FP-45 is a premium model, and its cost reflects the advanced features like Protosound and detailed construction. For budget-conscious hobbyists, this may be a significant investment.

2. **Complex Assembly and Setup**

- Like many high-end models, the FP-45 may require assembly, wiring, and initial setup, which can be time-consuming for beginners. Some users may need to troubleshoot sound or motor issues during the process.

3. **Space and Track Requirements**

- The FP-45 is a large locomotive, requiring ample space on the layout. Operators with limited track real estate may find it challenging to integrate smoothly.

4. **Maintenance and Repairs**

- Advanced features like Protosound and DCC compatibility mean there are more components that could potentially fail or require maintenance. Users must be prepared for occasional repairs or replacements.

5. **Limited Availability of Parts**

- As a specialized model, finding replacement parts or accessories (e.g., specific sound chips, wiring components) may be difficult compared to more common models.

6. **Learning Curve for Sound and DCC Features**

- The Protosound system and DCC programming offer advanced functionality but also require learning. New users may find it overwhelming to fully utilize these features without some research or guidance.

7. **Potential for Overkill for Small-Scale Operations**

- If you primarily run the locomotive on small loops or simple layouts, the FP-45 s advanced features may feel unnecessary. For such setups, a simpler or less expensive model might suffice.

---

### **Conclusion and Recommendation**

The **MTH 20-2145-1 Gauge FE EMD FP-45 Diesel (Protosound)** is an exceptional model for enthusiasts who prioritize realism, sound quality, and detailed craftsmanship. It is ideal for operators with larger layouts, a passion for digital command control, and the budget to invest in a high-end locomotive. The Protosound system and accurate detailing make it a standout choice for those who seek an immersive and authentic experience.

However, if you are a beginner, operate on a small layout, or prefer a more straightforward model, the FP-45 may not be the most practical choice. In such cases, a simpler DCC-compatible locomotive with basic sound features could be a better fit.

- You have a larger layout and want a realistic, high-performance diesel locomotive.

- You appreciate advanced sound systems and DCC functionality.

- You are willing to invest in a premium model for long-term enjoyment and collectibility.

- You are on a tight budget or prefer a more affordable model.

- You lack experience with DCC or advanced sound systems.

- Your layout is small, and the FP-45 s size would be impractical.
