Thanks Mike, for starting a new thread on the snow plows! Often very fascinating C&S info turns up as a side conversation in an unrelated thread, thereafter buried there, invisible to later searches.

Mike's point (correct me if I misstate anything) is that there was a "standard" C&Sng butterfly snow plow for decades, then in the late 1920s or early 1930s a variation was constructed as some locomotives were rebuilt and modernized.

In a discussion about the On3 and Sn3 snowplows that Overland imported with its C&S locomotives, Mike pointed out that the "standard" height of the plows from bottom of the blade to the top of the blade at track centerline was 42" (forget about the ovoid wings on the sides). This was measured to be true of the plows on C&S 60 and C&S 9. Mike pointed out that some locomotives had a similar but shorter blade, only 36" from bottom to top at center. These similar but shorter plows were found on the 2-8-0s that had been rebuilt with new smokebox fronts, flat without the UP era small extensions, and larger diameter doors that were secured in place with multiple flat dogs.

So, the 2-8-0s that retained the original extend smoke box front used the 42" tall plows, while any 2-8-0 with the modern flat smokebox front required a similar but shorter plow, to allow the new door to clear when opened. Number 9 was the exception as to new, flat smoke box doors, as its larger driver diameter and the seat on the cylinder saddle allowed the new door to clear the top of the 42" plow.

So let's look at some photos (my favorite part!) . . .

First number 9 vs number 10 with plows:


1936


1931


Now the larger 2-8-0s, B4-Ds and up:


1920


1933


1931


1923, long before acquiring flat face


My unfinished 1924 version of 71 in Sn3.  The Overland Sn3 plows came in 2 versions, both 42" tall. This plow from OMI number 9.


Otto Perry's 1926 version of 71.


1934 view of 71--still has the original smoke fox front.


Couldn't find a photo of the final version of 71 with a plow, but this is a photo of the On3 Overland model that I found on eBay a few years back.


1931


1936


Flat faced number 74 in 1934



Both views above of 74 in 1941


1934


1935


The CB&Q cousin in 1932


If anyone has a photo of the last version of 71 with a plow, please post it.

Has anyone ever seen a photo of number 76 with a plow?
