Re: Diamond stacks again

Thanks, Wade. I appreciate the info.
I got my information, as well as a copy of shop drawings from Burnham of the 473-478 fake stacks from Jackson Thode. The 476 version had no drawings.
I fully agree with the comment about bad dates in photo captions. I would seriously question any date showing 478 with a "new version" fake stack before 1961. The 1961 steel coaches in the consist are a dead giveaway, and I have seen bad captions like that before. Check to see if the airpump platform is in place, those were removed in '61. At least they were in place in '60 and gone in '62. That's a real good way to pinpoint a date.
As to #476, it is rare to find any pictures of this engine without a fake stack after 1954, when it was sporting the 473's original. By '57, the stack had either been replaced or modified to it's final version (until the incident Earl wrote about with the backhoe) and it was there to stay. Even after the "incident" with the backhoe scoop, no one was prepared for how quickly Burnham replaced it.
