Sardinia Depot and Facilities

[NW Mailing List]

Bob:  You have seen all that I have of Sardinia  some years ago at the CRRC
slide shows I gave.   I have never found a photograph of the north side of
the depot and the coal wharf in 15 years of searching.  I do have some shots
of he depot from each end that give very slight hints of what lay behind the
depot.   But, they are more like teases than useful shots.

Subject: RE: Transposition Brackets

Gary Rolih, This is not about the Transportation Brackets but a question on 
the Peavine. Do you happen to have any photos of the Engine facility at 
Sardina Ohio. Located there was an elevated coal unloading track,a steam 
powered bucket ( Steam from the engine), Sand tower, Hostler's
Shanty.Also at Sardina were two water tanks, on the Hilsboro "Y', and the 
water teratment building.If you happen to have photos of such It would be 
very helpful in my completing  the area in HO. I have the Station completed.

                 Thank You,
                                                                         Bob
