CHEYENNE, Wyo. — Fabrication work is underway for Union Pacific 4-8-8-4 Big Boy No. 4014. UP steam workers have finished disassembling the boiler to allow workers to access the frame and fabricate new internal parts before the locomotive can be reassembled.

Ed Dickens, senior manager of heritage operations, says the disassembly was a “moment of amazement,” saying that fully removing the boiler from the rest of the locomotive “hasn’t been seen around here since the mid-1950s.”

Shop workers have made new rod brasses, top boiler check valve parts, and lubricator check valves. The various parts will be installed, along with several new boiler components soon.

Dickens and the steam crew say that UP Northern-type 4-8-4 No. 844’s annual inspection is nearly finished, hinting that the locomotive may be out on the railroad’s mainline again in 2017.

“There are some trips currently being considered, but nothing to announce yet,” said Dickens about No. 844.

All of the railroad’s steam restoration projects take place at its shop complex in Cheyenne.

CORRECTION: An earlier version of this report included a reference to new wheelset manufacture. Union Pacific steam crews are only inspecting wheelsets at this time.
