The Transportation Safety Board says a damaged wheel on the train led to a fiery train derailment in New Brunswick in January.

The CN train -- carrying crude oil and liquefied petroleum gas -- derailed near Plaster Rock, N.B., on Jan. 7, causing a large fire and the evacuation of 150 nearby homes.

The TSB says the derailment occurred when the train was trying to stop after an emergency alarm was activated. Engineers on site discovered a broken wheel. The wheel, made in 1991, broke because of "fatigue," which caused a rim to shatter, the TSB stated in a progress update released Thursday.

The wheel met the standards for 1991, but didn't undergo the same inspection process as wheels manufactured today, the TSB stated.

The track was also damaged in the derailment.

Two tank cars were punctured, which released oil and caused the fire. The punctures were likely caused by impact with another car. Other cars were damaged following the derailment.
