Authorities said a group of 20 to 25 youths boarded a MARTA train bound for Atlanta's airport, and viciously attacked the passengers.
Police said one of the teenagers bashed one rider in the face with a soda-pop can, pushed him down and stole his wallet. Another passenger on the southbound train was punched in the face.
Police said both of the riders who were attacked work for Delta Air Lines, and have been staying at a hotel near Hartsfield-Jackson Atlanta International Airport.
The Delta workers - including one from Gig Harbor, Wash., and the other from New York City - suffered cuts in the attack late Saturday night south of downtown Atlanta.
MARTA spokesman Lyle Harris said police are still investigating, and no arrests have been made.
