Epping, North Dakota

RailWorks crews constructed the track infrastructure for Crestwood Midstream Partners’ COLT (crude-oil loading terminal) Hub and performed two capacity expansions.

RailWorks installed about 34,000 feet of release and departure tracks and six turnouts as well as a full-timber crossing and a 94-foot concrete trough. Weather and other challenges compressed the project timeline.

The Epping hub loads crude oil from trucks and pipelines into refinery-bound Burlington Northern Santa Fe Railway unit trains. It’s among the United States’ largest transload facilities in terms of daily volume. COLT Hub moves an average of 120,000 barrels of crude oil a day by rail and can store up to 1.2 million barrels.

Unique Features

North Dakota endures some of the coldest winters in the United States. For much of this project, the workers were facing minus-15-degree Fahrenheit morning temperatures. The weather became much colder during the last few weeks of November and continued into December, when work halted temporarily. After temperatures turned more cooperative in the spring, a crew returned to the project.
