What we have here is a discouraging matter of timing in that the 6406, a train of empty PPLX hoppers, had stalled at MG and had to await rescue helpers to come up from Altoona to shove. It got moving once more just as symbol CAEL was approaching on No.3 track, evidenced by the hi-cube boxcars visible beyond the signal bridge. A few more seconds before the hoppers got going might have made for a nice side by side shot. I believe one of the haulers on the PPLX train was down as three SD40s should have handled the empty train.
