CTA seeking new rail lubricant after fire

By ABC7
July 5, 2010 (CHICAGO) An electrical arc between the running rail and the restraining rail near the Clark and Division stop caused the fire. The arc set fire to the grease used to keep the wheels running.

The CTA now wants a substance with a higher flashpoint.

The current lubricant burns at 300 degrees. A previous test of a grease with a higher threshold didn't perform as well.
