Hamblen Rd will be closed for a while at the train tracks. A small piece of the track came off and caused a train to derail.---------------------------------------UPDATE: 3:30 - Hamblen is now open. It appears that one of the bridge pylons sank into the river, which caused the piece of track to break apart.---------------------------------------There were no injuries reported. A few people on Facebook reported that the bridge had collapsed, but that is not accurate. It is still intact.Union Pacific Railroad Police are investigating, and HPD is diverting car traffic (and water traffic on the San Jacinto) away from the area. 
lease avoid the area, and use Kingwood Dr or Northpark to enter/exit Kingwood. I will update this if anything new is reported. 4951
