UP 5500 a COFC Z train starts it climb out of the valley, at Valley Mini-yard running on the main line. Far in the background a SD-40 waits on the siding (center track), what i call the builders track is the third line. This is the track where mostly east bound and occasionally west bound trains are build ( are were build) in 05-07. To the right of the photo the vacate land is now filled with homes and business. The yard isn't as busy with a train being build once every few days instead of every day. Alot has changed in the three years since this photograph was taken.
