During the Chessie Era, the three partners C&O, B&O,
and WM, adopted the colorful blue, yellow and orange
Chessie System livery with the Chessie Cat logo. All
units retained their original identity until the creation
of CSX Transportation. CSX renumbered most units and
painted over the road letters. WM units were rare to
begin with and not often photographed by Chessie System.
This SD40-2, far from home on its way from New Orleans,
was still in Chessie paint with its identity intact as
it passed through Biloxi, MS. Note the original lettering
peeking through the Chessie logo. All SD40's are now in
the new CSX "Bright Future" scheme.
