Those pesky slow zone on CTA rail lines just won't go away.
In fact, this year slow zones have grown almost 61% from February of 2010 - 108,405 feet of track are covered by slow zone as shown on the Feb.16 map, vs. 67,398 feet on the Feb. 24, 2010 slow zone map.
About 2,700 feet of slow zones were added in the State Street subway last June when an electrical arc ignited curve greases used to reduce the screeching noise of wheels on the metal track. The fire burned some of the track that was previously repaired in 2008.
A bystander captured this dramatic video showing smoke billowing out of the tunnel during the June fire.
The CTA could not say when work on that slow zone between Chicago and North/Clybourn would be completed.
There was some good news on slow zones in January, when the CTA announced signal repairs were completed on the Orange Line, and that long slow zone was lifted.
