M520-03 with the csx RF&P heritage unit. 

caught M520-03 in Brentwood Sunday August 3rd with the RF&P heritage unit in the consist. I got information from a friend and fellow railfan that it was coming up nirth6from Birmingham. it was dead in tow, because of damage done during its trip our west on the U.P. during a trip into Mexico. video coverage of it isn't the best, but its another catch. I got better photos of it about an hour later.
