Executive Summary
Committed to the safety, reliability, and efficiency of its operations, c2c Railway Limited, a key operator in the rail infrastructure sector, recently took a proactive step in their condition-based maintenance protocols, integrating IRISS Safe-Connect™ overtemperature indicators into select areas of their electrical systems.
With IRISS’s passive, always-on monitoring solution in place, c2c gained continuous insight into the condition of electrical connections without relying solely on periodic inspections. Now, thermal risks are identified earlier, fewer intrusive inspection activities are required, and the team operates with greater confidence in the system.
Challenge
Maintaining electrical reliability in rail operations’ electrical systems presents ongoing challenges, particularly when it comes to identifying issues before they result in failures. Traditional inspection methods, such as periodic thermal imaging, provide valuable data but are inherently limited by lengthy stretches of time between inspections.
As a result, emerging thermal issues between inspection intervals can go unnoticed, increasing the risk of unplanned outages or safety incidents. c2c needed a solution that could provide continuous visibility into electrical connections without adding complexity or disruptions.
Solution
c2c turned to IRISS Safe-Connect™ thermochromic overtemperature indicators, passive heat condition monitors that permanently change color when electrical connections exceed a critical temperature threshold. Through simple observation, overtemperature indicators give maintenance teams a clear visual alert during routine checks.
Overtemperature indicators run without power, configuration, or system integration. A color-changing indicator signals abnormal thermal conditions. The indicator stays purple under safe temperatures, but changes to bright pink when the equipment exceeds 70° Celsius. Maintenance teams can be alerted to potential issues during routine visual checks without any additional steps.
For c2c, that simplicity was the ultimate goal. By deploying overtemperature indicators across key connection points, the team gained continuous monitoring capability without increasing maintenance burden or requiring intrusive access.
Outcome
The implementation of Safe-Connect™ thermochromic overtemperature indicators has provided c2c with a clearer picture of what’s happening inside their electrical systems as well as more confidence in what they are not seeing.
With continuous, passive monitoring in place, the team can identify abnormal thermal behavior earlier and act on it before it becomes a problem. This has reduced the need for repeated intrusive inspections and made maintenance more targeted in the process.
The safety case is straightforward: detecting potential failure points before they escalate protects both personnel and the infrastructure.
“Innovative technology doesn’t have to be complex,” said Paul Meenan, head of M&E, c2c Railway Limited. “Solutions like this give users reactive feedback in a passive manner, offering levels of confidence you simply can’t achieve with traditional fixed electrical systems.”
Key Takeaways
Passive monitoring provides continuous insight without adding complexity
- Early detection of thermal issues supports safer, more proactive maintenance
- Reducing intrusive inspections improves efficiency and lowers risk exposure
- Simple, color-changing indicators require no training, no tools, and no interpretation: teams either see a problem—or they don’t
