Ok, this is a post of what I saw on my trip to DC.
THURSDAY
-Fog plagued the signals all the way to the CSX Toldeo near Detroit Metro, indicating a Red-Red.
-Inside Ohio, in the yard, 3 AC4400CW's #68, #745, and I did not see the other number.
-Off the salt mine near the Ohio Turnpike 2 WLE Geeps and a Rent-a-Wreck.
-Also, a pair of NS SD's raced us to an overpass, never got close to see numbers.
-In DC, they are replacing the old Pennsy Light Position for newer signals.
-Also, a GEVO and an 8700 Series were on a hotshot.
SUNDAY
-Salt Mine yielded an EMD Demo and a WLE Geep.
-Ohio Yard: NS #4117 on a local run, a CSX Geep, AC4400CW #781 and GEVO #4705, and finally at the north end of the yard was AC4400CW #119 and another unit that looked to be a GEVO.
