Looking for prototype info.

Hey guys. so yeah, I'm an old hand at Trainz... and now kinda need your help to track (no pun intended) down some prototype info on a rare locomotive. I know, at some point in the past, another user was working on making a model of this particular locomotive, but abandoned the project due to not knowing how to do scripting... whatever the case I'm hoping you can help me out here.

So, what I need, if anyone has them handy, are the prototype plans for the Davenport Duplex Geared locomotive. Yeah, I know, that's a weird one... but I don't know where else to really post this for help.

Ignore my signature at the bottom. That's obsolete, plan to remove it.
