I was thinking about selling my Post War 1055 Texas Special (or as I like to call it "not so special") engine. Looking on eBay to see what they're selling for, I came across this picture from a completed auction.
A previous owner modified it and installed a toggle switch at the E-Unit slot so it would run in reverse.
I think this is a brilliant solution and will try doing the same thing to my Texas Special.
Just thought I'd share.
