Ron, thanks for the correction on the RI E-6's. I've corrected my earlier post. Frankly, I couldn't find a photo of the RI units, and I didn't look closely enough at the RI artwork which, in hindsight, is very much like an E-6's sloped nose.
As for including a dome in the GS set, I'm trying to represent The Texas Special and LIONEL produced a dome for it when it, like the GS, never had a dome.
A really good friend from my days in Chicago was the late Rich Sherry, and one of his best PW LIONEL F3 repaints for customers was that wild RI livery. Every time I see it I'm reminded of him.
Thanks, again, for the correction.
