What is marta police?

As an AI language model, I do not have access to any current information about MARTA police. However, MARTA (Metropolitan Atlanta Rapid Transit Authority) has its own police department that helps maintain safety and security for its passengers and employees. The MARTA Police Department has over 400 sworn officers, making it the ninth-largest police department in Georgia. The officers receive specialized training in dealing with transit-related issues and are equipped to handle emergencies on MARTA trains and buses. The department also has its own K9 unit, SWAT team, and investigations unit.
