What started out as a major crash resulting in a total freeway shutdown early Thursday morning has ended with the roadway reopened, as Houston police continue to investigate how it all went down.

Harris County deputies said the 18-wheeler was not hauling anything when a Union Pacific train hit the big truck near Klein Oak High School early Tuesday morning. No injuries were reported.

Investigators said the driver was speeding with their hazards on when their vehicle left the roadway and hit a barrier before crashing into the 18-wheeler.

Police have not shared details on what led up to the crash or what the 18-wheeler was hauling, but there is a shipping container on its side.
