Metro Making Several Changes In Wake Of Light-Rail Derailment
"Human error" caused a Metro train to derail just after midnight on June 16, according to Metro officials, but engineers from Arup, a firm hired to assist in the investigation, say that Metro needs to implement a safer lubrication system on the rails.
Pictures from the investigation, released by Metro at a press conference this afternoon, show gouge marks on
the concrete and rail along the stretch of track where the derailment occurred. Metro plans to test the track "to verify its structural integrity" with ultrasound, a yearly test that costs about $3,500.
Steve Clark, and engineer with Arup, says that these kinds of accidents don't happen very often, adding, "It's unusual for us to get involved in derailment investigations."
