Prioritizing Third-Rail: Why Aging Systems Are the Next Big Transit Risk

Steven Halbert’s article, “Prioritizing the Third Rail: Why Aging Systems Are the Next Big Transit Risk,” explores a critical challenge in public transportation infrastructure: the growing risks posed by aging third-rail systems. Many of these power delivery systems have been in service for decades—often exceeding 25 years—resulting in reduced efficiency, higher maintenance costs, and increased difficulty in sourcing replacement parts. As transit authorities face rising ridership and infrastructure demands, outdated systems present significant operational and safety concerns.

The article advocates for proactive modernization through Capped Aluminum Power Delivery (CAPD) third-rail technology, which offers superior electrical conductivity, durability, and corrosion resistance. CAPD rails also improve safety, energy efficiency, and sustainability, making them a future-proof solution for rail networks. By investing in these advanced systems now, transit agencies can reduce long-term costs, enhance reliability, and ensure their networks remain resilient in the face of growing transportation needs.

This piece serves as a call to action for rail industry leaders, transportation planners, and infrastructure decision-makers to prioritize upgrades before aging systems become a major liability.
