PERRY, Okla. -- Authorities are working to determine what caused a Union Pacific train to derail about five miles north of Perry Thursday around 11 a.m. 

Authorities said some of the train cars are carrying hydrogen peroxide.

Fire crews are on scene spraying the leaking tanks.

No injuries have been reported so far. 

This is the second reported trail derailment in Perry in the last two years.

Jan. of 2011 a BNSF train carrying fertilizer derailed in Perry causing the cars to spill the hazardous material. 

Authorities said the train tracks were damaged in the accident and parts had to be replaced. 

Residents were evacuated in the area but officials later determined the leak was not a danger to the community.

Officials are still working to determine the cause of that derailment.
