Review ATLAS Scale Master Silver Alco S2 Diesel Locomotive Rio Grande #117 Dnr

The **Atlas 40002141 Scale Master Alco S2 Diesel Locomotive Rio Grande No. 605** is a meticulously crafted model that captures the raw power and industrial elegance of mid-20th-century American railroading. Built to an exacting 1:64 scale, this dynamic replica embodies the robust engineering of the Alco S2 class, a workhorse designed for heavy freight and branch-line service during the diesel transition era. The Rio Grande Southern Railroad (DNR), one of the most storied shortlines in the American West, operated this locomotive with distinction, hauling coal, lumber, and agricultural goods across the rugged terrain of Colorado and New Mexico. The model faithfully replicates the DNR s distinctive livery a deep, weathered black with a bold, contrasting yellow stripe running along the sides, accented by crisp white lettering and numbering. The Alco prime mover, a symbol of the era s industrial might, is rendered with impressive detail, from the intricate radiator grilles to the precise placement of the long hood s ladders and handrails. The cab, though simplified for modeling purposes, retains the classic Alco silhouette, complete with a functional-looking window frame and a detailed door handle. Underneath, the chassis is engineered for smooth operation, featuring a robust, die-cast metal frame that supports the model s weight and ensures stability on the track. The wheels, cast in durable metal, are designed to roll true, while the couplings and knuckle pins add authenticity to the locomotive s articulation. For enthusiasts of operational models, Atlas has equipped this S2 with a high-quality, two-pole motor that delivers reliable performance, paired with a precision-geared drive system for consistent speed and acceleration. The attention to historical accuracy extends to the model s interior, where subtle details like the cab s bench seating and control panel outlines hint at the locomotive s operational complexity. Whether displayed on a static layout or integrated into a dynamic model railroad, the Atlas 40002141 stands as a testament to the Alco S2 s enduring legacy a bridge between steam s golden age and diesel s mechanical revolution. Perfect for collectors who appreciate both the artistry of model railroading and the engineering prowess of the past, this locomotive is a centerpiece that brings the spirit of the Rio Grande Southern s rugged operations to life.

### **Pros and Cons of buying a Atlas 40002141 Scale Master Alco S2 Diesel Locomotive (Rio Grande 117 DNR N0605)**

1. **Historical Accuracy and Detail** The Atlas model is well-regarded for its attention to detail, including accurate paint schemes, decals, and interior features. The Rio Grande 117 class (DNR) was a significant diesel locomotive in Western railroading, particularly with the Denver & Rio Grande Western (D&RGW) and later Union Pacific. This model captures that heritage effectively.

2. **High-Quality Construction** Atlas is known for durable plastic construction, precise tooling, and smooth operation. The S2 diesel series is part of Atlas s "Scale Master" line, which typically includes features like detailed cabs, accurate lighting, and well-fitted parts.

3. **Compatibility with Modern Trains** The model is designed for N-scale (1:160) operation, making it compatible with most modern N-scale layouts, including digital command control (DCC) systems. It likely includes DCC-ready features, such as a sound decoder slot and proper wiring for realistic operation.

4. **Collectible and Investment Potential** Rio Grande and Alco S2 locomotives are popular among collectors, especially those focused on Western railroads. This model could appreciate in value over time, particularly if it remains in excellent condition.

5. **Realistic Sound and Operation** If paired with a sound decoder (such as those from Bachmann, Lenz, or NCE), this locomotive can provide authentic diesel sounds, including horn blasts, engine noises, and realistic lighting effects. Atlas models often integrate well with sound systems.

6. **Versatile for Layouts** The Rio Grande 117 class was used in both freight and passenger service, making this model suitable for a variety of scenic layouts, from industrial yards to mountain railroads.

7. **Proven Track Record** Atlas has a long history of producing reliable N-scale locomotives. This specific model has likely undergone testing for durability and functionality, reducing the risk of early failures.

1. **Cost** High-quality N-scale models, especially those with detailed paint schemes and historical accuracy, can be expensive. This Atlas locomotive may cost several hundred dollars, depending on availability and condition. Buyers should weigh this against their budget.

2. **Potential for Wear or Damage** Even from reputable sellers, pre-owned models may show signs of wear, such as chipped paint, misaligned parts, or worn-out wheels. Inspecting the model closely before purchase is essential.

3. **Sound System Requirement** While the model is DCC-ready, it will not function with realistic sounds without an external decoder and battery pack. This adds to the initial cost and maintenance requirements.

4. **Limited Availability** Specific roadnames (like Rio Grande DNR) and paint schemes may be harder to find than generic models. Buyers might need to search multiple sellers or wait for restocks.

5. **Maintenance Needs** Like all plastic models, this locomotive may require occasional cleaning, lubrication of moving parts, and potential repairs if parts become loose or damaged over time.

6. **Space Requirements** N-scale locomotives take up less space than larger scales, but they still require dedicated storage if not used frequently. Collectors with large inventories may need to plan accordingly.

7. **Market Fluctuations** The value of collectible models can fluctuate based on demand, rarity, and economic conditions. While this model has historical appeal, its long-term value is not guaranteed.

### **Conclusion and Recommendation**

The **Atlas 40002141 Scale Master Alco S2 Diesel Locomotive (Rio Grande 117 DNR N0605)** is a well-crafted, historically accurate model that appeals to enthusiasts of Western railroading and Alco diesels. Its strengths lie in its attention to detail, compatibility with modern train systems, and collectible value. However, the higher cost, potential maintenance needs, and requirement for additional accessories (like a sound decoder) should be considered carefully.

- **Buy if:** You are a serious N-scale collector, enjoy Western railroading history, and are willing to invest in a high-quality model that may appreciate over time. Ensure you have space for storage and are prepared for potential maintenance.

- **Consider alternatives if:** You are on a tight budget, prefer a simpler model, or are unsure about the long-term commitment of maintaining a detailed locomotive.

- **Where to buy:** Purchase from reputable sellers (eBay, train stores, or model railroad auctions) and inspect the model thoroughly for damage or wear. Newer models from Atlas may be available directly from their distributor or authorized retailers.

For most dedicated hobbyists, this model is a worthwhile addition to a collection, provided expectations are realistic regarding cost and upkeep. If you prioritize realism and historical representation, the investment will likely be satisfying.
