This is a photo snapped May 2005 immediately following the clean up of a 5 car derailment at Cochrane Yard. The cars involved were heavily loaded covered gondolas of concentrate which would explain the amount of damage to the track. The area you see is the Transfer Switch which runs off the Main.  The actual Transfer Tracks can be seen to the left. While the derailment was occuring, the 5 cars actually pulled the lead portion of the Transfer tracks almost parallel to the Main which exhibits a prime example of the amount of damage that's caused when 200,000 pound cars derail.
