Cold And Silent

Kirkwood, Missouri. December 31, 2004.

This is a view looking inside the now dormant firebox of Union Pacific Big Boy X4006. At one time, fire raged inside this firebox creating the heat that turned water into the steam needed to propel this mighty steam locomotive. Big Boy X4006 is one of many steam locomotives on display at the St. Louis Museum of Transportation.

  1. Very cool image!  Having stood beside one of these before, this is deeper than it looks.  Will be neat when the UP gets the one they are working on running again.

  2. Thanks, Shelly Gunderson​. According to this website, the firebox grate area is 150 square feet.

  3. didn't I comment on this earlier? hmm a grand edition to SteamySunday​
