From a plaque on a wall inside NRR’s Main Terminal Station:
The sleeping kitten seen on our sign boards is named Chessie. She used to work for the Chesapeake and Ohio Railway. When the C&O evolved into the CSX Corporation, Chessie was let go. We found her wandering the intertracks and decided to give the old gal a new home.
I am delighted to discover there is a photo from the day we met, all those years ago.
