Re: NTS Walthers head scratcher?

James Dick asked:
"Could you however put a better dating (by decade, by year if possible) on the statement in your last paragraph of:

'The Accurail car represents cars with late R+3/4 improved Dreadnaught ends; this model, with its 4/4 improved Dreadnaught ends (hopefully with early taper) has more utilty for the steam-to-diesel transition era modeler.'"

Improved Dreadnaught ends evolved over time.  The ones on the first postwar AAR boxcars built after WWII had 3/4 or 4/4 ends (depending on car height) with major corrugations with a "rolling pin" taper (Jeff English's terminology, popularized by John Nehrich).

The end design was later modified with a rectangular top rib c. April 1948.  Again, cars had a narrow or wide top rib, again depending on car height (r+3/4 or R+3/4).≤-20682.jpg

Finally, the design was revised with a smoother "banana" taper (Jeff's terminology again) c. 1954.  This is the end found on the Accurail and Front Range models.
