Unfortunately I do not, I think Photoshop would let you do that, so it might be possible. I'm working with a laptop (Photoshop=Strangled, merciless death) and a high school budget, but I did most of my decal work in Word or Paint and used 'Shop as clean up, so I never touched the fonts in it that much. As a plus, I've enjoyed being able to get in the new member posts about wanting decals and say "Hey, you don't need fancy programs to start out with. Their nice and I have used Photoshop, but you can get away with the stuff that comes on most of our computers anyway" I was gonna show you the Ringling decals I did, but I can't find the file right off. I can show you a Chesapeake logo I duplicated with stock fonts (Times New Roman and I think Lucinda Script) and a line tool, just to show off a little bit: I had to redo the tails off the L a bit, you can tell it's not as curvy, and at some point I should respace the A and the K a bit more, but I imagined the thing as a decal on a toolcar or something, so I wanted to make my own.

Here is a link to some railroad fonts that might be helpful if you manipulate them with a drawing program. I believe most of these were traced, so they should be accurate.
Although no longer neededby the OP if you Google "identifying fonts" there are a lot of programs out there that could help.
