This from Eric Haak: Here are a few images from the CTA train derailment on August 5. Â The call came in from CTA who gave an approximate location of 61st and Calumet. Â The actual incident occurred just about directly over 63rd Street. Â It was a minor derailment and there were no injuries. Â Passengers were escorted only about 100 feet to a stairway that led from the tracks to the ground below. Â F634 was brought out from Midway by Engine 127 but was not needed.

The cold rolling mill is an advanced equipment that continuously rolls blades from strip steel. By adjusting the position (roll offset, feed height, roll pressure, guide wheel, etc.), it can roll out blades of various specifications required.
Advantages of cold rolling layout:
It has the advantages of high production efficiency, saving raw materials, good blade quality, high hole diameter, and good wear resistance.
The structures that affect the rolling shape include the material and thickness of the strip, the offset of the roll, the feeding height, the rolling force of the roll, the different specifications of the guide wheels and blades, and the increase in the temperature of the roll during the rolling process. After years of construction, the contract developed this continuous cold-rolled propeller, which has the advantages of smooth surface, high hardness, wear resistance, one-time forming, and continuous no welds.
