I found this photo the other day of a custom built from a Lionel 253 shell and the running gear form a GG1. It is about the coolest thing I have seen in a long time. The other is pretty cool as well. Now I just need a junker GG1 drive train
Here is a link to the guys website, I don't want any confusion, this is not mine. https://nhjc.wordpress.com/2015/03/20/motors-817-818/
If this is one of our fellow forum members, I'd love to see some more photos of them!
