IMHO means in my honest opinion, in my humble opinion.
I know railroads are a business, and everyone is running as lean as possible, but, I miss the Chessie days with the nicely painted locos. I railfan NS and CSX, and about the only difference you see on NS is the occasional gray ghost ( unpainted unit in primer), and not as yet painted Conrail, but on CSX at least in my area, you see lots of foreign power, CN, BNSF, SOO, UP etc. which tends to break things up .
What I wouldn't give to see a nice Chessie SD40-2 or GP38 or GP40 in the multicolored Chessie paint scheme from the 70's.
