MARTA riders traveling to and from DeKalb County this weekend should expect increased police activity at one Blue Line station.

The agency's police department will conduct a simulated training exercise at the Decatur station on Nov. 5, MARTA officials recently announced. 

The training exercise, named Operation Deep Impact, begins at 11:30 p.m. and is expected to last until 3 a.m. Plan ahead because rail service at the Decatur station will end at midnight.

A bus bridge will run between the East Lake and Avondale MARTA stations from 11:30 p.m. until service ends.  

Similar training exercises will also happen that evening in north Fulton at the Sandy Springs MARTA station
