Like a view through a porthole of a worker in a shipyard, here is a member of Union Pacific’s Steam Shop crew grinding in the firebox of 4-8-4 No. 844, looking through the firebox door opening in the cab. The famous locomotive is getting some off-season work done on the firebox around the mud ring, superheater tubes, and other maintenance, as seen in the shop at Cheyenne, Wyoming, on March 25, 2013.
