C&O Chessie System Hopper

I have spotted A C&O Chessie System covered hopper #604814 up in York, Paa few weeks ago(1-21-03). I was wondering if someone out there might be able to get me more info on it. Or at least where to look.

I spotted two on a southbound CSX freight at Relay Md. (South of Baltimore)on 2/24/03). It was good to see Chessie again. Two bad CSX didn’t keep the logo.
