Review INTERMOUNTAIN Dme Diesel Loco Cab Dc. Inch City Of Rochester

The **InterMountain 69372-02 DME SD40-2 Diesel Engine** paired with the **69384-01 6363 Rochester Fuel Injection System** represents a robust and reliable powerhouse designed for heavy-duty rail applications, particularly within the EMD (Electro-Motive Diesel) SD40-2 locomotive series. This engine is a refined iteration of the legendary **645E3** series, delivering a balanced blend of power, efficiency, and durability tailored for freight and passenger service. The **69372-02 DME (Digital Modular Electronics)** system integrates advanced diagnostics, real-time monitoring, and precise fuel management, ensuring optimal performance while minimizing downtime. Engineered with a **16-cylinder, two-stroke cycle** design, it produces a substantial **3,000 horsepower** at 900 RPM, making it a cornerstone for locomotives requiring sustained power over long hauls. Its **turbocharged** architecture, featuring a high-efficiency turbocharger, maximizes airflow for superior combustion, while the **intercooler** further enhances cooling efficiency, reducing thermal stress on critical components.

The **69384-01 6363 Rochester Fuel Injection System** complements the engine by delivering precise fuel metering and atomization, ensuring consistent power output and reduced emissions. This system incorporates **unit injectors** for accurate fuel delivery, minimizing waste and improving fuel economy a critical consideration for rail operators managing extensive fleets. The **mechanical and electronic controls** within the Rochester system work in tandem with the DME to adjust injection timing dynamically, adapting to varying load conditions while maintaining reliability under extreme operational demands. Together, these components form a cohesive power train that excels in both **freight and passenger service**, where reliability, fuel efficiency, and low maintenance requirements are paramount.

Built to withstand the rigors of continuous rail service, the **SD40-2 s engine assembly** incorporates **forged crankshafts, high-strength connecting rods, and precision-machined cylinder liners**, all designed to endure the high torque and cyclic stress inherent in locomotive operation. The **wet sleeve design** of the cylinder liners facilitates easier maintenance and replacement, extending the engine s operational lifespan while reducing long-term costs. Additionally, the **air intake system** is engineered to filter and condition air efficiently, protecting internal components from abrasive contaminants that could otherwise accelerate wear. The **lube oil system** is similarly robust, featuring a **high-capacity oil cooler** and **fine filtration** to maintain optimal viscosity and lubrication under varying thermal conditions.

For operators, the **InterMountain 69372-02 DME SD40-2** offers a compelling combination of **proven EMD engineering** and **modern digital diagnostics**, making it a favored choice for railroads seeking a balance between legacy performance and contemporary efficiency. The **6363 Rochester fuel injection system** further enhances this by ensuring clean, consistent combustion, which not only boosts power output but also aligns with stricter emissions regulations. Whether deployed in **freight service** for hauling bulk commodities or in **passenger trains** requiring smooth, dependable performance, this engine and fuel system combination delivers the endurance and adaptability needed for modern rail operations. With **minimal modifications required** from the original EMD design, it retains the reputation for **unmatched durability** that has made the SD40-2 a staple in North American rail fleets for decades.

### **Pros and Cons of Buying an Intermountain 69372-02 DME SD40-2 Diesel (69384-01 6363 Rochester) Locomotive**

#### **Pros**

1. **Proven Reliability** The SD40-2 is a well-established model with a strong reputation for durability, especially when properly maintained. Many units have operated for decades with minimal major issues if cared for correctly.

2. **High Performance** The SD40-2 is a powerful locomotive, capable of handling heavy freight loads and long-distance hauling. Its 3,000 horsepower (depending on engine) provides strong acceleration and climbing ability.

3. **Wide Availability of Parts** As a classic EMD model, parts are still widely available, though some may require sourcing from specialty suppliers. The Rochester prime mover (6363) is a robust engine known for longevity if maintained.

4. **Potential for Restoration or Modification** If you have mechanical or electrical skills, this locomotive can be restored or upgraded. Some owners enjoy customizing older units for aesthetic or performance reasons.

5. **Lower Purchase Price Compared to New Units** Used SD40-2s are significantly cheaper than modern locomotives, making them an attractive option for operators on a budget.

6. **Established Operator Community** There are many hobbyists, short-line operators, and private owners who maintain and run SD40-2s, providing access to forums, repair guides, and shared knowledge.

7. **Good for Niche Applications** If you operate in a region where heavy-duty freight is common or need a reliable backup unit, an SD40-2 can be a solid choice.

---

#### **Cons**

1. **High Maintenance Requirements** Older diesel locomotives, especially those with high mileage, require frequent inspections, oil changes, and potential repairs. Neglect can lead to costly breakdowns.

- **Electronic engine controls** (older mechanical or hydraulic systems)

- **Modern diagnostics** (limited onboard fault codes)

- **Fuel efficiency improvements** (older engines consume more diesel per mile)

- **Emissions compliance** (may require retrofits to meet current EPA standards)

3. **Fuel and Operational Costs** Older diesel engines are less efficient than modern ones, leading to higher fuel consumption. Additionally, parts and labor for repairs can be expensive.

- **Worn-out traction motors or generators**

- **Corroded or failing electrical components**

- **Engine wear (pistons, rods, bearings)**

- **Transmission or coupling problems**

5. **Limited Resale Value** Unlike newer locomotives, an SD40-2 will not retain value well over time. If you plan to sell later, you may not recover much of your investment.

- **Emission standards** (may need retrofits)

- **Safety inspections** (higher scrutiny for older units)

- **Insurance costs** (premiums may be higher due to age)

7. **Dependence on Skilled Mechanics** Finding experienced diesel mechanics who specialize in EMD engines can be difficult, especially in rural areas.

---

### **Conclusion**

- **Experienced operators** who can handle maintenance and repairs.

- **Those running small fleets or hobby operations** where cost is a priority over cutting-edge technology.

- **Owners who enjoy working on locomotives** and are willing to invest time in upkeep.

However, if you are looking for a **low-maintenance, fuel-efficient, and modern** locomotive, a newer model (such as an EMD AC6000CW or GE Evolution Series) would be a far better investment. The SD40-2 is a **character locomotive** great for enthusiasts but not ideal for those seeking long-term reliability without significant effort.

---

### **Recommendation**

You have **mechanical experience** and can commit to regular maintenance.

You are operating in a **low-cost, low-regulation environment** (e.g., private track, hobby use).

You **enjoy restoring and modifying locomotives** rather than just running them.

- Engine compression test

- Traction motor and generator checks

- Electrical system integrity

- Frame and undercarriage condition

You need a **reliable, low-maintenance** locomotive for commercial use.

You lack **mechanical skills or access to experienced diesel technicians**.

You plan to **run it frequently without proper upkeep**, as breakdowns will be costly.

You are **not prepared for potential emission compliance issues**.

- **Used but well-maintained EMD SD70ACe or GE Dash 9-44CW** (better fuel efficiency, modern controls).

- **Smaller, modern switchers** (e.g., EMD SW1500, GE B23-7W) if you don t need heavy freight power.

- **Leasing or renting** a locomotive if you need short-term use without long-term commitment.

If you proceed with the SD40-2, **budget for at least 10-20% of the purchase price in annual maintenance** to keep it running safely. Otherwise, a newer locomotive may save you significant headaches in the long run.

Details:

It looks flawless. Intermountain has amazing detail. With city of Rochester It is in like new condition. This n scale Intermountain locomotive is DC operated, and DCC ready.

I have only ran it for about 40 min on my layout to verify its working condition.
