Weekend Steam: Big Boy 4014

Merle likes the Big Boy; I do, too!  The restoration of 4014 is still almost unbelievable.  The big engine needed serious boiler repairs, plus a complete teardown. This engine sat for more than fifty years, and the 4014 would have been an engine kit rather than an engine after being retired while in need of an overhaul, and then moldering for half a century. Union Pacific pulled in experts in steam and machining from around the country to make it happen.  They had not done this level of work on an articulated steam locomotive for sixty years.
