Greeley bus disaster
The Greeley bus disaster refers to a collision between a train and a school bus in 1961 that resulted in the deaths of 20 passengers, with an additional 17 injuries. It was the deadliest traffic accident in the history of Colorado.
Background
On December 14, 1961, bus driver, Duane Harms, was completing his route. Besides Harms, the bus also was carrying an additional 36 students on their way to school. Harms was 23 years old at the time of the incident.Around this same time, a Union Pacific streamliner, The City of Denver, was running 10 minutes behind of schedule. As it neared Greeley, Colorado, the train was traveling around 70 miles per hour.
Somewhere between 7:45 am and 8:00 am, the train and the bus were reaching the same point, which happened to be a diagonal crossing in a rural part of the city. These types of areas did not have proper signals or gates and were referred to as "passive crossings".
