Our Client
A leading freight railroad operator was experiencing a high volume of Line of Road delays due to traction motor failures that frequently required out-of-service shopping.
The Challenge
The railroad operator’s reliability issues were impacting service performance and driving up maintenance costs. Leadership sought a comprehensive root cause analysis to address the recurring failures. Key challenges included:
- Frequent traction motor failures were causing significant Line of Road delays.
- Out-of-service events were increasing maintenance workload and downtime.
- Root causes of failures were unclear due to limited historical failure tracking.
- Preventive maintenance practices lacked consistency and clarity.
Real Results Achieved Together
EFESO diagnosed insufficient lubrication as root cause of traction motor failures, reducing Line of Road delays by 21%.
Transformation Impact
- 6-Month Teardown Program
- Comprehensive Failure Review
- Root Cause Identification
- Maintenance Standards Upgrade
Our Approach
EFESO led a deep technical investigation to uncover underlying drivers of failure:
- Partnered with the client’s Heavy Maintenance facility to disassemble and analyze failed traction motors.
- Evaluated motor construction, historical usage, and maintenance records to build a complete failure profile.
- Diagnosed the primary failure trend as insufficient lubrication, previously undetected by standard inspections.
- Introduced a new lubrication-focused preventive maintenance standard based on findings.
