I decided to make a run out to Plymouth today for a few hours, wasn't a bad idea in my opinion, I also happened to run into fellow RRFan member C&OGP75745 while down there, great meeting you!
I'll let the photos and videos do the talking from here, enjoy!

This ES44AH leading steel train B523 around the curve in Plymouth may look like a normal GEVO, but it sure didn'tsound like one, this unit sports a phenomenal sounding (for the fact it's on a GEVO) 1st gen K5H horn. Normally GEVO's are fitted with K5HL horns.
I also tried playing with vertical orientation, I think it came out alright, what do you guys think?

A venerable low number series YN2 AC44CW and two DC GEVO's are close to full throttle as they lead CSX local L302 through Plymouth.

...and this train had no exception, the crew knew one of the railfans that was among me and the other railfans that were at the spot, they gave us a shout on the radio and a horn salute.
Kudos to the sun and clouds too, with the sun breaking out as I was about to hit the shutter button.
