Review LIONEL Part #504 Scale Gp-9 Shell Nos Ex

The Lionel 6308972002 and 6304666002 are meticulously crafted, high-end scale models designed to bring the unmistakable charm and power of a vintage **GP9** diesel locomotive to your model railroad layout. These pieces are part of Lionel s **504-scale** line, a meticulously detailed series that captures the essence of North American railroading with an emphasis on authenticity and performance. The **6308972002** represents the iconic **GP9-6**, a robust and versatile locomotive that dominated freight railroads from the mid-20th century through the 1970s, while the **6304666002** is a **GP9-6** in a striking **NOx (Norfolk & Western)** livery, complete with the railroad s bold, recognizable black-and-yellow scheme. Both models are built to **N-scale** proportions but scaled up to **504-scale**, offering an exaggerated, larger-than-life appearance that enhances their visual impact on any layout.

Under the hood, these locomotives are powered by Lionel s advanced **DCC (Digital Command Control)** technology, ensuring smooth, realistic operation with precise speed control, lighting effects, and sound capabilities. The **GP9-6** is equipped with a **highly detailed cab interior**, complete with authentic controls, gauges, and seating, allowing operators to step into the driver s seat and experience the locomotive s commanding presence. The **NOx GP9-6** (6304666002) further elevates realism with its **custom-painted body**, featuring the bold **Norfolk & Western** logo and numbering, along with **working headlights, running lights, and a detailed underframe** that includes realistic exhaust and coupling details. Both models are built on **strong, durable chassis** with **smooth-running axles**, ensuring long-lasting performance and stability on even the most intricate trackwork.

The **504-scale** design amplifies the locomotive s imposing stature, making it a commanding centerpiece on any layout, whether displayed alone or integrated into a larger railroad scene. The **GP9-6** is available in a classic **Union Pacific** livery (6308972002), while the **NOx version** (6304666002) offers a striking alternative for collectors and operators who prefer the bold, industrial aesthetic of the Norfolk & Western Railway. Both models are finished with **high-quality paintwork**, **metallic accents**, and **weathering effects** that give them a lived-in, authentic appearance. Whether you're a seasoned modeler or a newcomer to the hobby, these **GP9-6** locomotives deliver an unparalleled blend of **historical accuracy, visual grandeur, and operational excellence**, making them must-have additions to any serious model railroad collection.

### **Pros and Cons of buying a Lionel 6308972002 / 6304666002 504-Scale GP-9 (6-34666) NOx (New Old Stock)**

1. **High Quality and Authenticity** Lionel s 504-scale models are known for their detailed, accurate reproductions of real-world locomotives, including precise paint schemes, weathering, and mechanical components. The GP-9 is a classic American freight diesel, and this model captures its essence well.

2. **NOx (New Old Stock) Condition** The "NOx" designation means the locomotive is in excellent, near-mint condition with minimal wear. It has likely been stored properly and may have been part of a collector s display, making it a reliable purchase without the risk of major flaws.

3. **Proven Durability** Lionel s 504-scale models are built to last, with sturdy chassis, reliable motors, and durable paintwork. Many collectors report years of trouble-free operation with proper maintenance.

4. **Collectible Value** The GP-9 is a highly sought-after model, especially in NOx condition. Its value tends to appreciate over time, making it a solid investment for serious collectors.

5. **Compatibility** The model is designed for use with Lionel s O-scale track systems, including both AC and DC layouts. It also works well with compatible third-party track and accessories.

6. **Historical Significance** The GP-9 was one of the most widely used diesel locomotives in the U.S. during the mid-20th century, making this model historically significant for railfans and modelers.

7. **Resale Market Availability** Due to its popularity, parts and replacement components (such as motors, lights, or couplers) are relatively easy to find if maintenance is needed.

---

1. **High Initial Cost** NOx models, especially well-preserved ones like this, command premium prices. The cost may be prohibitive for casual hobbyists or those on a tight budget.

2. **Maintenance Requirements** While durable, Lionel s 504-scale models require occasional cleaning, lubrication, and potential repairs (e.g., replacing worn-out wheels or brushes). Some collectors may need to invest in tools or expertise to keep it running smoothly.

3. **Space and Storage Needs** The 504 scale is larger than many other model train scales (e.g., HO or N), requiring more space for layouts or display cases. This can be a limitation for smaller collections.

4. **Track and Accessory Costs** To fully enjoy this model, you ll need compatible track, structures, and scenery, which can add significant expense. Lionel s O-scale track and accessories are high-quality but not cheap.

5. **Learning Curve for Beginners** If you re new to O-scale or Lionel s 504 models, setting up a layout or troubleshooting issues may require research and patience. The complexity of the scale can be overwhelming for first-time buyers.

6. **Potential for Overcollecting** The GP-9 is iconic, but some collectors may end up acquiring multiple variants (e.g., different roadnames, paint schemes, or NOx vs. mint conditions), leading to high long-term costs.

7. **Limited Digital Features (Compared to Modern Models)** Unlike newer digital-era models, this NOx GP-9 relies on traditional control systems (likely DC or early AC). If you re interested in modern digital features (e.g., sound, lighting effects, or remote control), you may need additional upgrades.

---

The Lionel 504-scale GP-9 (6-34666) NOx is an excellent investment for serious collectors who appreciate authenticity, durability, and historical value. It offers unmatched detail and a strong resale market, making it a wise choice for those committed to O-scale modeling. However, the high upfront cost, maintenance needs, and space requirements may deter casual hobbyists or those new to the scale.

If you re passionate about railroading, enjoy the craftsmanship of vintage-style models, and have the space and budget to support it, this locomotive is a fantastic addition to any collection. For beginners or those on a budget, it may be better to start with a more affordable model before investing in a high-end NOx piece.

- **Buy it if:** You re a dedicated O-scale collector, have experience with Lionel models, and want a high-quality, historically accurate locomotive that will appreciate in value.

- **Avoid it if:** You re a beginner, space-limited, or unwilling to invest in additional track, scenery, and maintenance.

- **Alternative Consideration:** If the price is too high, look for similar models in "like-new" or "excellent" condition (rather than NOx) or consider newer digital models if you want modern features.
