Based on photos I see and their description I believe Mina Nevada had another railroad depot.
So this building on the photo above is a Railroad Depot in Mina Nevada. The photo was taken on June 1951.
We already have several photographs of the main Mina Railroad Depot. You can see it here and another one here. And it looks like this was the other one. At least it was called so.
It captures the Mina Nevada Railroad Depot with locomotive number 5259 which was called the Cow and locomotive 5502 which was called the Calf. These locomotives are standing on the Southern Pacific main line.
Cow and Calf! How cool and cute! My kids are going to love that!
I love this photo and it is so great to see the history of Mina Nevada and what was here on this spot in the past.
