Not much available on this road. Atlas steel rebuilt was offered years ago, if you can find one?
I converted a PS-1 into an EJ&E using Tichy Train Group O scale decals here - https://www.tichytraingroup.co.../c/eje3/Default.aspx
Album #48 on my site - https://steves3roscale.shutterfly.com/pictures/15848
Album # 50 has an MTH version but its scheme is reversed and incorrect - https://steves3roscale.shutterfly.com/pictures/16257
I discovered the EJ&E years ago while on my way to the Libertyville Motorola Plant for cellular training.
Good luck,
Steve
