WASHINGTON (WUSA) - Metro officials announced on Tuesday that train speeds may be reduced to 35 mph in above ground sections during extreme heat.
Metro track inspectors will be using devices like infrared thermal "guns" and direct contact gauges to check rail temperatures. If temperatures higher than 135 degrees on a section of the rail are detected, a slow order will go into effect on that rail line.
The speed reduction is intended to prevent accidents like the one that occurred on the green line on July 6th when a heat kinks developed on the rail causing it to derail.
"While these speed restrictions may cause some delays and inconvenience, they are intended to put the safety of our passengers first," said Dave Kubicek, Metro's Deputy General Manager for Operations.
Metro officials may also implement reduced train speeds if the average median temperature is prolonged for a 3-day period with insufficient nighttime cooling.
