Y6b sand domes

[NW Mailing List]

I was aware of sandbox variations on the six Y5’s modified for yard hump service.  These Y5’s had larger sandboxes either designed differently or modified from the standard Y5/Y6 sandboxes.  I was unaware that there were any other sandboxes designed and used on other Y5 and Y6 classes until this thread of emails showed up on the mailing list.

I reviewed the list of mechanical drawings in the Archives and sure enough, there is a drawing E45446 dated 12/3/1952 for a larger front sandbox with four filler caps for the Y6b.  I will have to research some more for more details if there is a listing of engines these were applied to.  I was able to look at the photos the Archives has on line and the only Y6b’s I could find having the front four filler cap sand boxes were 2192 and 2194.

This is a good find.

I have seen photos or video of two Y6b's with very large forward sand domes, numbers 2192 and 2194. Does anyone know how many and what numbers of the Y6b's got these larger domes and if they were built that way or retrofitted? Thanks, Ed Burnett
