Review MTH Twin Cities And Western Diesel Ln/box

The **Twin Cities Western GP-20 Diesel Line/Box** (Model MTH 30-2686-1) is a meticulously crafted, high-performance diesel locomotive model that captures the raw power and timeless charm of mid-20th-century freight railroading. Engineered by MTH (Model Train Express), this HO-scale (1:87) model is a faithful representation of the iconic GP20 series, a workhorse diesel that dominated American railroads during the golden age of steam-to-diesel transition. The GP-20, part of the General Motors Electro-Motive Division s (EMD) legendary GP series, was designed for reliability, durability, and brute strength, and this model honors those qualities with striking attention to detail. Built with a robust, die-cast metal chassis and a durable, two-axle (B-B) truck setup, the GP-20 delivers smooth, realistic motion across your layout, whether hauling freight cars through rugged mountain passes or pulling a long consist of boxcars and gondolas across vast plains. The model features a fully articulated, articulated-axle (AAR-compliant) design, ensuring accurate wheelbase and a natural, rolling gait that mimics the real thing. Its body is constructed from high-quality, injection-molded resin, painted in a crisp, weathered finish that evokes the patina of decades of service think faded blues, grays, or earthy browns, often accented with bold road numbers and railroad logos that stand out against the backdrop of a bustling yard or a sprawling industrial corridor. The GP-20 is equipped with MTH s **SoundTraxx** system, which includes realistic diesel engine sounds, horn cues, and even subtle exhaust puffing for an immersive auditory experience. For those who appreciate authenticity, the model includes **DCC-ready** functionality, allowing for advanced control over lighting, sounds, and even dynamic braking effects, making it a versatile addition to any modern or legacy DCC layout. The **box cab** design, with its distinctive sloped roof and wide, functional windows, is both functional and iconic, offering a glimpse into the utilitarian yet imposing presence of these locomotives on real railroads like the Union Pacific, Burlington Northern, or Southern Pacific. Whether displayed as a standalone centerpiece or integrated into a sprawling freight yard scene, the Twin Cities Western GP-20 Diesel Line/Box is a testament to MTH s commitment to blending historical accuracy with modern modeling innovation. Perfect for enthusiasts who seek both realism and performance, this model is a must-have for any diesel railfan s collection, promising hours of detailed assembly, customization, and operation that brings the spirit of American railroading to life.

The **Western GP-20 Diesel Line/Box** (Model MTH 30-2686-1) is a popular HO-scale diesel locomotive model, particularly favored by model railroad enthusiasts for its realistic appearance and performance. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the MTH 30-2686-1 Twin Cities Western GP-20 Diesel Line/Box**

1. **High-Quality Construction**

The GP-20 is built with durable materials, including a sturdy metal chassis and precision-machined components. MTH is known for its attention to detail, ensuring smooth operation and longevity.

2. **Realistic Appearance**

The model closely resembles real-world Twin Cities Western GP-20 locomotives, with accurate paint schemes, lettering, and detailing. The body is well-proportioned, and the cab interior (in some versions) adds to its authenticity.

3. **Strong Motor and Performance**

The GP-20 is powered by MTH s **DCC-ready** motor (compatible with both DCC and DC control systems). It delivers smooth acceleration, good traction, and consistent speed, making it suitable for both mainline and branch-line operation.

4. **Sound Effects (Optional)**

While the base model does not include sound, MTH offers optional sound systems (e.g., **SoundTraxx** or **MTH Sound**) that can be retrofitted. When equipped, the locomotive produces realistic diesel sounds, including horn blasts and engine noises.

5. **Compatibility with Accessories**

The GP-20 is designed to work well with MTH s **SoundTraxx** system, allowing for advanced features like dynamic braking, lighting effects, and even animated features in some versions.

6. **Popular Roadname Options**

MTH has released multiple versions of this model under different railroads, including the **Twin Cities Western**, **Southern Pacific**, and others. This flexibility allows collectors to choose a specific roadname they prefer.

7. **Good Resale Value**

Due to its popularity and reputation for quality, the GP-20 holds its value well in the used market, especially well-maintained examples.

8. **Easy to Maintain**

The model is relatively straightforward to service, with accessible components for cleaning, lubrication, and minor repairs.

---

### **Cons of the MTH 30-2686-1 Twin Cities Western GP-20 Diesel Line/Box**

1. **Higher Price Point**

Compared to some other HO-scale diesel models, the GP-20 is on the pricier side, especially when considering optional sound systems or premium roadnames.

2. **Weight Considerations**

While not excessively heavy, the GP-20 is a bit heavier than some lighter plastic-bodied locomotives. This can make it less ideal for very small layouts or those with limited track space.

3. **Potential for Wear Over Time**

Like all high-quality models, the GP-20 can experience wear on the wheels, axles, or motor brushes over time, requiring occasional maintenance to keep it running smoothly.

4. **Limited Dynamic Features in Base Model**

The base version lacks advanced features like dynamic lighting or sound unless upgraded. Enthusiasts who prioritize these features may need to invest in additional accessories.

5. **Compatibility with Non-MTH Systems**

While the motor is DCC-compatible, some users report that certain DCC systems (especially budget-friendly ones) may not provide the same level of performance as MTH s proprietary systems.

6. **Occasional Paint or Lettering Issues**

Some early production runs or certain roadname versions have had minor inconsistencies in paint quality or lettering, though MTH has generally improved this over time.

7. **Space Requirements**

The GP-20 is a larger locomotive, which may not be ideal for very tight layouts or those with limited storage space.

---

### **Conclusion**

The **MTH 30-2686-1 Twin Cities Western GP-20 Diesel Line/Box** is an excellent choice for model railroaders who prioritize realism, performance, and durability. Its strong motor, accurate detailing, and compatibility with advanced sound systems make it a standout model. However, its higher cost and slightly heavier weight may deter some collectors, particularly those on a tight budget or operating on very small layouts.

For enthusiasts who want a **versatile, high-quality diesel locomotive** that can serve as a centerpiece on their layout, the GP-20 is a **highly recommended purchase**. Those who prefer a more budget-friendly option or smaller locomotives may consider alternatives like Bachmann or Life-Like models, but they will likely sacrifice some of the GP-20 s realism and performance.

**Final Recommendation:**

If you are looking for a **durable, realistic, and well-performing HO-scale diesel locomotive** and can accommodate its size and price, the **MTH GP-20 is an outstanding investment**. Consider adding optional sound or lighting systems if you want to enhance its functionality. For collectors who prioritize roadname variety, MTH s other versions (e.g., Southern Pacific) are equally worthy. However, if budget or space constraints are a concern, explore other models first before committing.
