Radium was a Station on the Denver & Salt Lake line, nowadays on UP's Moffat line and is some 55 miles North and West of Dillon, the nearest C&S location.
Thanks again.
Kind of curious why the previous owner of my layout had Depots for these two locations.
I am using one as a stand in for Buena Vista now. A may end up living there permanently.
As Chris Walker noted:
Radium was a station on the Denver & Salt Lake RR (later D&RGW)
Location is east of Yarmony Colorado.
Railroad buildings included a depot and section houses.
Not much evidence remains.
I tried viewing some photos on line and there are 1 or 2 buildings near the track that might be former railroad structures.
It has been some time since I last went through Radium and I would need better views to determine that situation.
