WASHINGTON (WUSA9) -- Today's derailment took place very close to where two Red Line trains collided back in 2009, the deadliest crash in the history of the Washington Metro.
There have been other incidents along that same stretch of track in recent months.
Metro officials say it's all a coincidence and that none of these incidents are related. That includes another derailment about half-a-mile-away four-months ago.
That train was also leaving the same Brentwood rail yard. But metro officials say the root cause of those two derailments is very different.
"The issue here today had nothing to do with track conditions or track infrastructure. The low-speed yard derailment that you're referring to was quite a different situation. The conditions and the situations in the rail yard are very different than the conditions you'd see on active track. So at this point, I can say there's nothing at all to indicate that these two scenarios have anything to do with each other," said Caroline Lukas with WMATA.
Then there's the collision of two red line trains in 2009. That took place just about two metro stops away from today's derailment. Metro officials say there's no correlation.
"For our red line riders, safety and security is our number one priority. We did extensive work and testing here this afternoon before putting any trains into revenue service. We take that very seriously. So we want our customers to know that's our number one priority and we ensure that we get them to where they need to go safely."
