METRO has identified the cause of a derailment that occurred on June 16.
The incident occurred 27 minutes past midnight during a training exercise with only an instructor and two trainees on board. There were no injuries.
An independent investigation concluded that excessive speed around the curve at Braeswood and Greenwood caused the two-car train to derail. The train was traveling 22 mph in a 15 mph-zone.
METRO asked the consulting firm, ARUP North America, to make independent recommendations to enhance METRORail safety. The international and design firm's recommendations include the following:
- Establish uniform speed of 15 mph in this location instead of the three current speed limits of 15, 30 and 20 mph.
- Review and augment training of METRORail instructors
- Ultrasonically test the rail to verify its structural integrity (METRO conducts these tests annually).
- Analyze and assess tight curves in the five, new lines METRO is building
METRO has adopted these recommendations and is implementing them.
