Tyson,
It looks like you've done some really fine work with those engines!
I, at one time, not too long ago, had this pipe dream of building an N scale version of the L&N's Cumberland Valley Div.
I wanted it to be in the early 60's, so I could use as many as 5 paint schemes on the engines, & have both the newer bay window cabeese, & the old "woodies".
But alas, one more big scheme of mine that never got off the ground. (yet...

)
That is one thing that I love about the early 60's L&N, was that wonderful hodge podge of 1st, & 2nd generation diesels that you would see lashed together, sometimes 6 or 8 to a consist, & always plenty of Alco's, belching that black smoke...
Ahhhhh...just the thought of all those diesel fumes brings a tear to my eye, & a lump in my throat...
BTW - The weathering on those Alco's is really fine!
They look like the real McCoy!
