Hi Paul:
Look in the back of Ron Ziel's "Steel Rails to the Sunrise."
There you will find a terrifc drawing of an articulated LIRR steam locomotive.
It's a great, detailed drawing, but the locomotive never existed.
That's somewhat of the point I was trying to make. Perhaps someone thought it would look cool to draw the K4 in "Sunrise Special" service! (I couldn't imagine the PRR allowing the LIRR to paint something other than "Pennsylvania" across one of their tenders, seeing how strict and finicky they reportedly were according to all my "old-timer" friends.)
While that locomotive may have been a K4s and used on the LIRR (I'd have to check my roster of Pennsy equipment leased to the LIRR) it was not allowed over the bridge.
Who knows . . .Perhaps there were plans in the works at the time to allow this, and the bridge issue wasn't considered at first.
Then again, perhaps they were planning on the bridge being replaced sooner and that may have been a prototype drawing.
There are all sorts of possible answers for the rendering of that drawing.
Now . . . .if anyone has a photograph (untouched, I might add) of the K4 posed at, say, Southampton, or Montauk in 1927, then I will eat my proverbial straw hat and report the information to my LIRR "factual source!"
Let me know what you find out, but I doubt the Smithsonian would know about the LIRR's bridge/weight problem of that time.
But one never knows, do one?
