ST. LOUIS, MO (KTVI) – Power is finally restored to the U.S. Bank building in downtown St. Louis after an underground transformer exploded Tuesday at around 5 in the evening.

It took Ameren crews 13 hours to fully restore power to the south side of the building. Power on the north side was not impacted by the explosion.

Fire department officials say an electrical transformer in an underground vault is to blame for the fire and explosion.

Fortunately, no one was near the vault was happened, and no one was injured.

Still, the explosion caused plenty of shock and inconvenience for those who work in the building.  The 36-story building was evacuated, but at least 10 people were trapped in elevators.  Firefighters rescued those stranded people, and then used a dry chemical to smother the electrical fire.

Ameren crews were able to restore power by bypassing the damaged transformer.  Ameren Underground Services Division Director John Luth says transformer explosions happen very rarely, and the cause is still being investigated.
