Introduction

The National Transportation Safety Board (NTSB) has issued urgent safety recommendations to the Southeastern Pennsylvania Transportation Authority (SEPTA) regarding fire risks in its Silverliner IV rail cars.

Safety Concerns

The NTSB has urged SEPTA to eliminate fire risks in the Silverliner IV rail cars. The board’s findings indicate that the design of these rail cars, coupled with SEPTA’s maintenance and operational procedures, creates an unacceptable safety hazard. This is due to the frequency and intensity of electrical fires that can spread to areas occupied by passengers.

Underlying Issues

The NTSB determined that the risks associated with the Silverliner IV design cannot be completely mitigated without either a detailed fleet retrofit or full replacement of the cars. The current operating protocols at SEPTA have not adequately protected passengers and crew members, as evidenced by the continued use of rail cars with identified defects in passenger service.

Recommendations and Response Time

The NTSB issues urgent recommendations to address immediate, critical issues that threaten lives or property and recipients have 30 days to respond.
