Railcar Cooling Solutions
A Case Study in High-Performance Temporary HVAC
Delivering Critical Cooling for Railcar Blasting & Relining Operations in Extreme Ambient Conditions
Executive Summary
Resilient Energy Solutions was engaged to design and deliver a comprehensive temporary cooling solution for a critical railcar maintenance operation. The project required maintaining safe, productive working conditions inside four railcars undergoing internal abrasive blasting and relining in extremely high ambient temperatures.
Our team engineered a high-capacity, flexible cooling system featuring dual 25-ton air conditioning units supported by a 150-kW diesel generator. Custom ductwork provided targeted airflow through individual drops into multiple hatches on each railcar. The complete turnkey installation—including design, mobilization, setup, and teardown—enabled the customer to complete the maintenance work ahead of schedule while ensuring crew safety and comfort in challenging conditions.
The client expressed exceptional satisfaction with both the performance of the equipment and the professionalism of the installation, validating Resilient Energy Solutions expertise in mission-critical temporary HVAC and power solutions for industrial rail applications.
The Challenge
Railcar maintenance involving internal blasting and relining presents unique environmental control demands. Workers must operate in confined spaces where abrasive blasting creates dust, heat, and physical strain, while relining processes often involve temperature-sensitive coatings and adhesives. When ambient temperatures are extremely high, internal car temperatures can quickly become unsafe and unproductive.
Key technical requirements included:
Sufficient CFM (cubic feet per minute) airflow to effectively cool and ventilate four full-size railcars simultaneously.
Flexible distribution system capable of delivering conditioned air through individual drops into multiple hatches—accommodating varying access points on the railcars (top, side, or bottom configurations).
Reliable operation in extreme high-ambient conditions where standard HVAC equipment would be stressed or underperform.
Rapid deployment and minimal disruption to ongoing yard operations, with full turnkey responsibility from the provider.
A standard off-the-shelf cooling approach would not suffice. The installation required careful engineering of duct routing, power distribution, and equipment placement in a dynamic rail yard environment.
Our Solution
Equipment & Capacity
Resilient Energy Solutions deployed a robust, high-performance cooling package specifically selected for demanding industrial environments:
Two (2) 25-ton industrial air conditioning units — providing a combined 50 tons of cooling capacity with high CFM output suitable for large, enclosed volumes and high heat loads.
One (1) 150 kW diesel generator — delivering reliable prime or standby power with sufficient capacity to run both AC units plus ancillary equipment, even in remote or grid-constrained locations.
Custom-engineered ductwork and distribution system — featuring individual flexible drops precisely positioned to serve different hatches on each of the four railcars, ensuring even temperature control and effective air circulation throughout the work zones.
Turnkey Delivery Model
Beyond equipment supply, Resilient Energy Solutions provided complete turnkey services that removed all burden from the customer:
Site assessment and cooling load calculation tailored to railcar dimensions and work processes.
Equipment mobilization, positioning, and interconnection in the rail yard.
Professional installation of duct runs and hatch-specific drops with attention to safety, access, and operational flow.
Startup, testing, balancing, and operator training.
Full teardown, equipment removal, and site restoration upon project completion.
This end-to-end approach ensured seamless integration with the customer's maintenance schedule and zero unexpected downtime related to climate control infrastructure.
Results & Impact
The cooling system performed flawlessly throughout the duration of the project. By maintaining comfortable and safe internal temperatures despite extreme outdoor conditions, the crews were able to work continuously and efficiently without heat-related fatigue or safety incidents.
Most significantly, the customer completed the railcar maintenance campaign ahead of the original schedule. The accelerated timeline delivered direct operational and financial benefits—allowing cars to return to service sooner and reducing overall project costs associated with extended equipment downtime.
The client was extremely satisfied with both the technical performance of the cooling solution and the professionalism of the Resilient Energy Solutions team. Feedback highlighted the reliability of the equipment, the effectiveness of the custom distribution design, and the smooth execution of the turnkey installation and removal process.
Key Outcomes
Schedule Performance: Maintenance completed ahead of schedule, enabling faster return-to-service for the railcar fleet.
Workforce Productivity: Comfortable internal conditions eliminated heat stress, supporting continuous high-quality work.
Client Satisfaction: Customer described as "super happy" with the setup, performance, and overall service delivery.
Operational Flexibility: Individual duct drops accommodated diverse hatch configurations across all four railcars without compromise.
