I call this T&P depot #2---the one patterned after St. Louis Union Station. Also the same one that burned circa 1904.
The existing modern depot(dating from 1931), I call #3.
The depot at the northeast corner of the T&P-GC&SF crossing, I call #1, though there were probably two or three depot upgrades built in that vicinity.
