Review LIONEL 622-100/ #622/623/624/6220/6250 Nw2 Diesel Motor And Unit

The Lionel 622 series of N-scale diesel motor units represents a meticulously crafted and highly detailed replica of the iconic New York Central (NYC) and Pennsylvania Railroad (PRR) diesel locomotives that once dominated American railroads in the mid-20th century. This collection includes the 622-100, 622-5, 622/623/624, 6220, and 6250 models, each designed to capture the essence of these powerful and influential machines with unparalleled authenticity. The motor units are built upon Lionel s advanced NW2 diesel motor system, a robust and efficient propulsion solution that delivers smooth, realistic operation and impressive acceleration, making them ideal for both static display and dynamic operation on your model railroad layout. The bodywork of these locomotives is constructed from high-quality, durable materials, featuring finely detailed panels, rivets, and surface textures that replicate the weathered, industrial aesthetic of their full-scale counterparts. The cab interiors are particularly noteworthy, offering a wealth of intricate details such as instrument panels, control levers, and seating arrangements that bring a sense of realism and immersion to your railroad scene. The undercarriage is equally impressive, with meticulously crafted couplings, wheelsets, and suspension components that enhance the locomotive s operational realism while also providing a sturdy foundation for long-term use.

One of the standout features of the Lionel 622 series is its attention to historical accuracy, with models like the 622-100 and 622-5 paying homage to the iconic EMD F7 and F9 diesel engines that were staples of the NYC and PRR fleets during the 1950s and 1960s. The 622/623/624 variants further expand the collection, offering variations in paint schemes and liveries that reflect the diverse operations of these railroads, including everything from bold road numbers to subtle corporate markings. The 6220 and 6250 models, in particular, showcase Lionel s commitment to versatility, with the 6220 serving as a versatile diesel unit that can be paired with other Lionel cars or even converted into a different configuration, while the 6250 introduces a slightly larger and more robust profile, ideal for hauling heavy freight or passenger trains with ease. The NW2 diesel motor unit is a game-changer for modelers, offering consistent power output, precise speed control, and a quiet, efficient operation that minimizes wear on both the locomotive and your track infrastructure. Whether you re running a bustling freight operation or a meticulously themed passenger service, these motor units provide the reliability and performance needed to keep your layout moving with authenticity.

Beyond their operational capabilities, the Lionel 622 series is designed to be a centerpiece for any N-scale layout, with its bold presence and detailed craftsmanship drawing the eye and sparking conversation. The paint schemes are vibrant yet realistic, with careful attention to shading, weathering, and panel lines that give each locomotive a lived-in, authentic appearance. The inclusion of optional accessories, such as working headlights, dynamic lighting, or even sound effects in some variants, further enhances the immersive experience, allowing you to recreate the roar of a diesel engine or the glow of a locomotive s lights as it pulls into a station. For collectors and enthusiasts, these motor units are not just functional pieces but also prized additions to a railroad collection, offering a blend of historical significance, technical innovation, and artistic detail that sets them apart in the world of model railroading. Whether you re a seasoned modeler looking to expand your fleet or a newcomer eager to bring the excitement of diesel railroading to your layout, the Lionel 622 series delivers an unmatched combination of quality, performance, and visual appeal that is sure to elevate your railroad experience.

### **Pros and Cons of Buying a Used Lionel 622/100-5/623/624/6220/6250 NW2 Diesel Motor Unit**

#### **Overview**

The Lionel NW2 diesel motor units (including the 622-100, 100-5, 623, 624, 6220, and 6250) are classic, high-quality diesel locomotives produced by Lionel in the 1960s and 1970s. These units are sought after by model railroad enthusiasts for their realistic operation, durable construction, and historical significance. However, like any used locomotive, they come with advantages and challenges.

---

### **Pros**

1. **Realistic Operation**

- The NW2 motor units are known for their smooth, realistic diesel operation, including accurate sound effects (horns, exhaust, and engine noises) and responsive throttle response.

- The motor is a high-quality, durable unit that can last for decades with proper maintenance.

2. **Durable Construction**

- These locomotives are built with sturdy metal bodies, strong axles, and reliable electrical systems, making them more robust than many plastic or lower-end metal units.

- The NW2 motor is a proven design that has stood the test of time, with many units still operating well after 50 years.

3. **Historical and Collectible Value**

- The NW2 series is iconic in model railroading, especially among collectors. Units in good condition can appreciate in value over time, particularly if they are rare or come with original packaging.

- Owning a piece of Lionel history adds sentimental and nostalgic value for many hobbyists.

4. **Compatibility with Lionel and Third-Party Systems**

- These units are compatible with Lionel s track systems (including DCC and DC) and many third-party layouts.

- The NW2 motor can be adapted for DCC operation with the right converter or sound decoder, adding modern functionality while preserving the original appearance.

5. **Sound and Aesthetic Appeal**

- The original sound systems (especially on the 622-100 and 6250) are highly regarded for their authenticity.

- The paint schemes and detailing are well-crafted, with many units featuring realistic markings and weathering.

6. **Modification Potential**

- Enthusiasts can easily upgrade these units with modern components, such as LED lighting, improved sound systems, or DCC compatibility.

- The open design of some models (like the 6220) allows for easy access to internal components for repairs or upgrades.

7. **Strong Secondary Market**

- There is a vibrant community of buyers and sellers for NW2 units, making it easier to find parts, accessories, or even complete units.

- Websites like eBay, Facebook Marketplace, and specialty model railroad forums frequently list these units for sale.

---

### **Cons**

1. **Age and Wear**

- Many of these units are 50 years old, which means they may show signs of wear, such as rust, worn-out paint, or degraded plastic components.

- Original sound systems or electronics may be failing, requiring restoration or replacement.

2. **Maintenance Requirements**

- Diesel motor units require regular maintenance to keep them running smoothly. This includes cleaning the motor, checking brushes, lubricating axles, and addressing any electrical issues.

- Rust can be a significant problem, especially in units that have been stored improperly. Rust in the motor or chassis can lead to binding or failure.

3. **Cost of Restoration**

- Restoring a NW2 unit to peak condition can be expensive, particularly if parts are missing or worn out. Original components may be hard to find, requiring reproduction or custom fabrication.

- Labor costs for restoration (e.g., repainting, sound system repair) can add up quickly.

4. **Potential for Hidden Issues**

- Some units may have internal problems that aren t immediately visible, such as a failing motor, corroded contacts, or damaged wiring.

- Always test a used unit thoroughly before purchasing to avoid unexpected repair costs.

5. **Limited Modern Features**

- Unlike newer units, these locomotives lack modern conveniences such as built-in DCC compatibility, advanced sound systems, or LED lighting unless upgraded.

- Some users may find the lack of modern features limiting compared to contemporary models.

6. **Space and Storage Considerations**

- These units are larger and heavier than many modern plastic or smaller metal locomotives, requiring more storage space.

- The bulkier design may also make them less practical for smaller layouts or display cases.

7. **Market Variability**

- Prices for NW2 units can vary widely depending on condition, rarity, and demand. A well-preserved unit may cost hundreds or even thousands of dollars, while a heavily restored or damaged one could be a bargain or a money pit.

---

### **Conclusion**

Buying a used Lionel NW2 diesel motor unit is a rewarding but potentially challenging endeavor. These locomotives offer unmatched realism, durability, and historical value, making them a prized addition to any serious model railroad collection. However, they also require careful consideration of their age, maintenance needs, and potential restoration costs.

If you are a dedicated hobbyist with the time, skills, and budget to restore and maintain a classic locomotive, an NW2 unit can be an excellent investment both for its operational quality and its long-term appreciation potential. On the other hand, if you prefer modern convenience, lower maintenance, or a more budget-friendly option, you may want to consider newer models or alternative brands.

---

### **Recommendation**

- **For the Experienced Enthusiast:** If you have experience with model railroad restoration, enjoy the challenge of bringing a vintage unit back to life, and appreciate the historical significance of Lionel s NW2 series, purchasing a used unit is highly recommended. Focus on finding a unit with a solid motor, minimal rust, and intact sound systems to minimize restoration work.

- **For the Beginner or Casual Hobbyist:** If you are new to model railroading or prefer a more hassle-free experience, consider purchasing a pre-restored or lightly used NW2 unit from a reputable seller. Alternatively, explore newer diesel units from brands like Bachmann, Kato, or Life-Like, which offer modern features with less maintenance overhead.

- **For the Collector:** If your primary goal is to build a collection of vintage locomotives, an NW2 unit is an excellent choice, especially if you find one in good condition or with original packaging. Be prepared to invest time and effort into its upkeep, but the long-term value and satisfaction of owning a piece of model railroading history are well worth it.

Ultimately, the decision depends on your priorities whether you value authenticity, historical significance, and the hands-on experience of restoration, or if you prefer the ease and modernity of newer models.
