Union Pacific 4014...the "Big Boy" quietly rests after traveling across the state of Minnesota, reaching its northernmost destination of Duluth. While there was no formal photoshoot of the Big Boy at the Lake Superior Railroad Museum, the fine personnel of UP & LSRM rigged up lights and made for a night scene unlike any other.
