The Wilcox train robbery also known as the Wilcox Holdup was a train robbery that took place in the early morning of June 2, 1899 in the vicinity of Wilcox in Albany County, Wyoming.
A Union Pacific train was flagged down before it could cross a wooden bridge.
Armed men forced the train crew to separate the locomotive from the carriages.
A safe in one of the carriages was blown open by dynamite, and the robbers escaped with cash and other valuables.
[2] The robbery was considered unsolved at the time and later traced to Butch Cassidy and the Wild Bunch.
