Review ATHEARN Ho Scale Burlington Northern Locomotive

The **Athearn SDP40-BN (HO scale Burlington Northern #6398)** is a meticulously crafted, high-detail model that captures the robust essence of the legendary diesel locomotives that once dominated America s railroads during the mid-20th century. Part of Athearn s renowned *SDP40* series, this model represents one of the Burlington Northern Railway s (BN) iconic **EMD SD40-2** locomotives, specifically numbered **#6398**, a unit that would have roared through the heartland of the United States during its operational prime. The locomotive is rendered in an authentic **Burlington Northern livery**, featuring the railroad s bold, two-tone scheme of **dark green body panels** accented by **yellow stripes and lettering**, with a **white cab roof** and **black undercarriage**, all executed with Athearn s signature precision. The model stands proudly on a **fully articulated chassis**, allowing for smooth, realistic motion as it navigates curves and switches, a feature that enhances the immersive experience for modelers seeking dynamic operation.

The attention to detail on the **bodywork** is nothing short of exceptional, with **hand-painted panel lines, rivet patterns, and weathering effects** that bring the locomotive to life. The **cab windows** are clear and accurately proportioned, while the **front headlight assembly** is intricately detailed, complete with **separate lens pieces** and **reflectors** that catch the light realistically. The **coupler and knuckle** are of high-quality metal construction, ensuring durability and proper articulation, while the **pantograph** is fully functional, allowing for realistic power collection when used with compatible track systems. The **numbering and lettering** are crisply applied, with **Burlington Northern s bold, block-style markings** standing out against the green body, complete with the railroad s distinctive **logo and roadname** in white and yellow. Even the **ladders, handrails, and grab irons** are meticulously crafted, adding to the model s authenticity and making it a standout piece for any HO-scale layout.

Under the hood, the **SDP40-BN** is powered by Athearn s **DCC-ready motor**, delivering smooth acceleration and reliable performance, while the **sound system** (when paired with compatible decoders) can be programmed to emit the deep, rumbling growl of a diesel locomotive, complete with **horn sounds, bell chimes, and realistic engine noises** that bring the model to life. The **underframe** is equally impressive, featuring **detailed brake systems, air hoses, and ladders**, all rendered in fine detail to match the locomotive s operational complexity. Whether displayed statically on a shelf or operated dynamically on a layout, this model exudes the raw power and historical significance of the BN s fleet, making it a prized addition for any railfan or modeler seeking a piece of American railroad heritage. With its **high-quality construction, authentic detailing, and functional features**, the Athearn SDP40-BN #6398 is not just a model it s a tribute to the mighty diesel locomotives that once defined the golden age of American railroading.

### Pros and Cons of buying a Athearn SDP40-BN6398 HO Scale Burlington Northern Locomotive

#### **Pros:**

1. **High Quality Construction** Athearn is known for producing detailed and well-crafted HO scale models. The SDP40-BN6398 features accurate proportions, fine detailing, and a sturdy build, which enhances its realism and durability.

2. **Accurate Historical Representation** This model represents a Burlington Northern (BN) SD40-2 locomotive, which was a common and iconic diesel model in North American railroading. The livery and markings are well-researched, making it a historically accurate addition to any BN or Union Pacific (UP) collection, as BN later merged with UP.

3. **Sound and Light Features** The locomotive includes realistic sound effects (e.g., engine noise, horn, and bell) and optional lighting (headlights, running lights, and cab lights). These features improve the immersive experience for operators and observers alike.

4. **Compatibility with Modern Controls** The SDP40-BN6398 is designed to work seamlessly with digital command control systems (DCC), allowing for advanced operation features like speed control, sound programming, and even multi-locomotive operation.

5. **Durability and Longevity** Athearn models are generally built to last, with robust chassis and components that withstand frequent use. This makes it a reliable investment for serious modelers.

6. **Versatile Use** Beyond BN or UP layouts, this locomotive can be repainted or modified to represent other railroads that operated similar SD40 models, such as the Santa Fe, Chessie, or Norfolk Southern, expanding its versatility.

7. **Positive Community Reception** The model has received praise from hobbyists for its attention to detail and overall quality. Positive reviews and recommendations from the modeling community can be a strong indicator of its value.

#### **Cons:**

1. **Price Point** The SDP40-BN6398 is a mid-to-high-end model, with a price that reflects its quality and features. For beginners or those on a tight budget, this may be a significant investment, especially if they are purchasing additional accessories or track to complement it.

2. **Space Requirements** As a large HO scale locomotive, it requires adequate space on a layout. Operators with limited shelf or track space may find it challenging to accommodate this model comfortably.

3. **Maintenance Needs** While Athearn models are durable, they do require occasional maintenance, such as cleaning contacts, checking sound components, and ensuring smooth wheel rotation. Neglecting these tasks can lead to performance issues over time.

4. **Potential for Repainting or Modifications** If you plan to repaint or modify the locomotive to represent a different railroad, this adds time and effort to the project. Some modelers may prefer a ready-to-run (RTR) model without the need for customization.

5. **Sound System Limitations** While the sound system is realistic, it relies on batteries or an external power source. If the batteries fail or the sound module malfunctions, it can disrupt the operating experience until repairs are made.

6. **Compatibility with Older Systems** If you are using an analog (DC) control system, you may need to invest in a DCC converter or upgrade your setup to fully utilize the locomotive s features. This could add to the overall cost.

7. **Market Availability and Backorders** Popular models like this one can sometimes experience backorders or limited stock, especially during peak sales periods. This may require patience or alternative purchasing options.

### **Conclusion:**

The Athearn SDP40-BN6398 is an excellent choice for model railroad enthusiasts who prioritize quality, historical accuracy, and advanced features. Its detailed construction, realistic sound and lighting, and compatibility with modern control systems make it a standout model. However, its higher price point and space requirements may be barriers for some collectors or beginners. For those who are committed to building a realistic and immersive HO scale layout, this locomotive offers exceptional value and enjoyment.

### **Recommendation:**

If you are an experienced modeler with a well-equipped layout and a budget that can accommodate a high-quality locomotive, the **Athearn SDP40-BN6398 is highly recommended**. It is particularly well-suited for operators who enjoy digital control, sound effects, and historically accurate representations of North American diesel locomotives.

For beginners or those on a tighter budget, consider starting with a simpler or more affordable model to build foundational skills before investing in a premium locomotive like this one. Additionally, if you plan to repaint or modify the model, factor in the time and effort required for customization.

Ultimately, this locomotive is ideal for collectors who want a **durable, feature-rich, and historically accurate** addition to their railroad, enhancing both visual appeal and operational realism.
