So it turned out to be a moving sidewalk in the tunnel between C and D that caught on fire and not the Plane Train. They got the train working quickly but due to crowds they encouraged people going just to D to walk to free up the train for those going to E and F since they are further out. You could see where they were working in the moving sidewalk and it was burned up inside. The people conglomerating and bumbling around the tunnel around D Concourse were jamming the place up making it take forever to get anywhere.
