I just inherited one of the older-model Life-Like E8 models. It will need to be upgraded to DCC at some point. After searching around, I found this guy’s tutorial, and I’m re-blogging it here so that when I’m ready I can find it easily.
This guy also has a lot of other tutorials on many locos, so if you are looking for something, be sure to check it out!
I’ll post my own story of how the install goes when I get around to it.
