Both Tulsa and Oklahoma City plan on maintaining quiet by banning the use of train horns in some areas.

The "Quiet Zone" in Tulsa will be  enforced on five streets located south of the Brady District.  Oklahoma City wants to add further safety equipment to six streets and possibly close four intersections.  These will all be between Northwest 7th and Northwest 16th Streets. 

Some of the proposed improvements include adding gate arms, building a median or possibly closing a street.  Officials say these additions probably won't eliminate the noise but will significantly reduce it. 

"As the train approaches those various intersections, they're not required to blow their horn," said Dennis Clowers, Director of Public Works.
"But like I said, if the guy driving the train happens to see a car there's nothing to prevent him from doing that," he said.

The "Quiet Zone" project in Tulsa is taking longer than previously expected because many of their plans require more time.  Oklahoma City's plans for a this project have not yet been funded.  Clowers says that makes it difficult to estimate a start date.
