Historical Significance and Current Condition

​

Built in 1913, Soo Line No. 736 is a significant artifact of railroad heritage, representing a bygone era of rail transportation. NSP's team found the locomotive to be remarkably intact, a rarity for park-displayed engines that often suffer from exposure and vandalism.

​

The boiler, a critical component of the locomotive, was generally in good condition. The boiler barrel and the interior of the firebox were found to be in excellent condition, highlighting the potential for future restoration. However, further investigation is required around the steam dome due to signs of wasting and rivet corrosion. Of particular concern is the wrapper sheet around the firebox, which has shown significant deterioration. This component is crucial for the boiler's integrity, and would be the most costly to replace.

 

Cab and Appliances

The locomotive’s cab, while structurally sound, exhibited rotting in the lower portions and floor, likely due to prolonged exposure to the elements. Impressively, most of the control mechanisms, gauges, and valves remain intact. To prevent theft and further deterioration, NSP recommended that the city relocate these fixtures to a secure storage site.

​

Inspection of the locomotive’s appliances, including the injectors, air compressors, and dynamo, revealed a need for significant repairs. Piping and lubrication systems have deteriorated, and the absence of the whistle, presumably stolen, underscores the importance of enhanced security measures.

​

Tender and Structural Components

The tender, responsible for storing coal and water, showed extensive corrosion, particularly in the tank. If restoration is deemed feasible, a complete replacement is likely necessary to ensure the locomotive's operational viability.

 

Key Findings

Despite the areas requiring attention, several components of Soo Line No. 736 were found to be in good condition:

• Interior of the Firebox: Excellent condition, indicating good preservation of critical internal components.

• Boiler Barrel: Generally in good condition.

• Frame: Found to be in good condition, providing a solid foundation for potential restoration.

• Steam Chest: Cast new in 1937 and found to be coated in oil, preserving its interior.

• Running Gear: Found to be in good condition, essential for the locomotive's mechanical functionality.

 

Preservation and Next Steps

To safeguard Soo Line No. 736 for future generations, NSP recommended several immediate preservation measures:

• Removal of Lagging: Insulation retaining moisture around the boiler and backhead should be removed to prevent further corrosion.

• Protective Coatings: Applying protective coatings to exposed metal surfaces and addressing blisters in the paint will help stabilize the locomotive's condition.

• Secure Fixtures: Cataloging and storing vulnerable components, such as gauges and valves, will protect them from theft and environmental damage.

 

Future Restoration and Community Involvement

Looking ahead, NSP plans to conduct further detailed inspections, including ultrasonic thickness testing, to assess the feasibility of restoring the locomotive to operational status. This process will involve collaboration with city officials, industry experts, and the community to address logistical, financial, and legal considerations.

“The Soo Line No. 736 is more than just a piece of machinery; it’s a tangible link to our railroad past,” said NSP President Charles Elo. “With the right preservation efforts and community support, we can ensure that this historic locomotive remains a proud symbol of Appleton and Midwest railroad heritage.”

 

Get Involved

NSP invites the community to participate in preserving this significant piece of history. Fundraising efforts, volunteer opportunities, and public awareness campaigns will be essential to support the ongoing preservation and potential restoration of Soo Line No. 736.
