NORWALK - State police say they are stepping up patrols over the holiday season.
Authorities say starting today, commuters will begin seeing state troopers on trains, some in uniform, some not in uniforms and others with bomb-sniffing dogs.
It's all part of a stepped-up security initiative called Holiday Enforcement Operation 2010.
Troopers say they will be working hand-in-hand with local police departments to make sure the public transportation lines in southwestern Connecticut do not become targets of opportunity for terror.
However, they stress that even though there will be extra security on the trains, there is no specific threat to Connecticut's transportation system.
