As I mentioned elsewhere, I completed one of my projects that has been languishing on the shelf for roughly two years, the mounting of a Lionel EP5 shell onto an RMT GG-1 chassis, creating a freelance EP4 of sorts...
The completed chassis, with EP5 chassis ends bolted to the GG1 frame.
Headlight brackets fabricated from Erector set brackets. Fortescue points out how one of the brackets doubles as a speaker hold-down...
The RMT sound board was shot, so a Lionel horn board was replaced. The E-unit switch was relocated to the floor between the trucks, while the sound on/off switch was eliminated.
Homebuilt LED headlight unit avec Fortescue.
The chassis goes through its paces:
All in all, I'm glad to have this finished after all these years!

I still haven't forgot my UP GG-1 and SP Black Widow EP-4 ideas, after all.
