I'm not sure if there are any Paducah-specific GP38s, etc. but you can easily reskin a model to your liking using a photo editing program such as Gimp, Paint.net, Adobe Photoshop, or even JASC Paintshop Pro.
If you mean Paducha and Louisville then no, but there is a whole fleet of Evansville Western locos coming along shortly which will only need a logo edit to be near-enoughs for some of the PAL roster...
