NEAR LESTER, Iowa (KTIV) -
A preliminary investigation blames a broken rail for a train derailment that forced evacuation of several homes near Lester, Iowa in early November.
Burlington Northern Sante Fe says the faulty track caused 23 train cars to derail.
It happened on November fourth two miles south of Lester.
12 homes were evacuated for several hours when it was discovered a car carrying liquefied petroleum gas was damaged.
Authorities say the gas didn't leak out, but the area was cleared due to a fire risk.
The Federal Railroad Administration is still conducting its own investigation.
A spokesperson says it could be at least three months before that is complete.
