Review BACHMANN Ho Scale Colas Rail Freight Diesel Locomotive #70811 Ex/box

The Bachmann 31-591A HO scale model of the **CSX 70811 (ex-Conrail) SD70ACe** is a meticulously crafted representation of one of North America s most powerful and iconic freight locomotives, embodying the raw power and engineering prowess of modern railroading. This high-quality, ready-to-run (RTR) model captures the striking silhouette of the **General Electric SD70ACe**, a member of the legendary Dash 9 series, which has become a staple on Class I railroads across the United States. The 70811, originally built for Conrail in 1999 before transitioning to CSX in 2001, is a prime example of the locomotive s enduring reliability and versatility, capable of hauling heavy freight across vast distances with precision and efficiency. Bachmann s attention to detail shines through in the model s **photorealistic paint scheme**, featuring the bold, corporate blue and white livery of CSX, complete with crisp, accurately proportioned lettering and numbering that reads clearly from any angle. The **smooth, die-cast metal body** is complemented by **resin-cast details**, including the intricate cab interior with realistic controls, a detailed radiator grille, and a fully articulated, articulated coupling system that ensures smooth operation on your layout. The **DCC-ready sound system** (with optional Bachmann Sound or third-party decoders) brings this locomotive to life with authentic diesel sounds, including **realistic horn tones, exhaust cycles, and dynamic braking effects**, enhancing the immersive experience for modelers who seek both visual fidelity and auditory realism. Whether paired with a classic freight train or integrated into a dynamic freight operation, this model stands as a testament to Bachmann s commitment to producing **high-end, historically accurate HO scale locomotives** that appeal to both hobbyists and enthusiasts alike. Its **durable construction** and **scalable performance** make it a standout addition to any serious railroading collection, offering years of operational enjoyment and visual appeal.

### **Pros and Cons of buying a Bachmann 31-591A HO Scale Colas Rail Freight Diesel Locomotive (70811 Ex/Box)**

#### **Pros**

1. **High Quality Construction** Bachmann is known for producing detailed and well-built HO scale models, with accurate proportions, fine surface details, and sturdy assembly. This locomotive features realistic paintwork, decals, and weathering effects.

2. **Historical Accuracy** The Colas (Compagnie des Chemins de fer Large Voie d Anjou) was a French regional railway operator, and this model captures its distinct livery and branding. The attention to detail in the livery and markings makes it appealing to modelers who prioritize authenticity.

3. **Sound and Functionality** The locomotive likely includes Bachmann s DCS (Digital Command System) sound, which provides realistic diesel engine noises, horn sounds, and even subtle detail sounds like pantograph movement. This enhances the realism of operation.

4. **Prototype Representation** The 70811 class was a common freight diesel in France, and this model accurately represents its physical characteristics, including the cab design, body shape, and underframe details. This makes it suitable for both static display and operational use.

5. **Resale Value** Bachmann models, especially well-maintained ones in good condition, hold their value reasonably well in the secondary market. If you decide to sell later, this model may still attract collectors or hobbyists.

6. **Compatibility** The locomotive is designed for standard HO scale track, making it compatible with most HO gauge layouts, including those using DCC or DC control systems.

7. **Collectible Appeal** The Colas livery is not as common as some other European railroads, making this model a niche but desirable addition for collectors focusing on French or regional European railways.

8. **Easy to Maintain** Bachmann models are generally durable and require only basic maintenance, such as occasional cleaning of the wheels and brushes (if using DC) or ensuring proper DCS wiring.

#### **Cons**

1. **Price** New Bachmann HO scale locomotives, especially those with detailed liveries and sound, can be expensive. This model may cost between $150 and $250, depending on availability and retailer markup. Used copies may be cheaper but could come with wear or missing parts.

2. **Limited Availability** Some Bachmann models, particularly those with specific liveries or limited editions, may not always be in stock. Prices can fluctuate based on demand, and backorders are possible.

3. **Potential for Damage in the Box** Even if the locomotive is "ex/box," there is always a risk of minor damage (e.g., bent axles, scratched paint, or loose parts) from shipping or handling. Inspecting the model thoroughly before purchase is essential.

4. **Sound System Dependency** While the DCS sound is a major selling point, it requires a compatible sound decoder and power supply. If you don t already have these, additional costs will be incurred.

5. **Space Requirements** Like all HO scale models, this locomotive will occupy space on your shelf or layout. If storage is limited, you may need to prioritize carefully.

6. **Learning Curve for New Modelers** If you are new to HO scale modeling, assembling and operating a DCS-equipped locomotive may require some research and practice, particularly with wiring and sound setup.

7. **Potential for Counterfeit or Knockoff Models** Some third-party sellers (especially online) may offer fake or poorly made replicas of Bachmann models. Always verify the seller s reputation and the model s authenticity before purchasing.

8. **Maintenance Over Time** While Bachmann models are durable, prolonged use can lead to wear on the wheels, brushes, or sound components. Regular maintenance (e.g., lubricating axles, cleaning contacts) will be necessary to keep it running smoothly.

### **Conclusion**

The Bachmann 31-591A HO scale Colas rail freight diesel locomotive (70811) is a well-crafted, historically accurate, and visually appealing model that would be a valuable addition to any European-focused HO scale layout. Its realistic details, sound capabilities, and collectible nature make it a strong choice for serious modelers. However, the higher cost, potential for damage, and the need for compatible sound equipment are factors to consider before purchasing.

If you are a collector of French railways, a modeler who values authenticity, or someone looking to enhance a freight-focused layout, this locomotive is a worthwhile investment. For budget-conscious buyers or those new to modeling, it may be better to start with a simpler or less expensive model before committing to a premium piece like this.

### **Recommendation**

- **Buy if:** You have a strong interest in French rail history, enjoy detailed and sound-equipped models, and are willing to invest in a high-quality locomotive for your layout or collection.

- **Consider alternatives if:** You are on a tight budget, new to modeling, or prefer a different railroad or locomotive type. Look for used copies, older Bachmann models, or other brands like Lima or Kato for similar but potentially more affordable options.

- **Purchase from a reputable seller** to avoid counterfeit or damaged items. Inspect the model thoroughly if buying used, and ensure you have the necessary sound equipment if the DCS system is a priority.
