CHICAGO — The CTA has heightened security on buses and trains in light of the subway attacks this week in Moscow that killed 39 people, officials said.
CTA officials say more uniformed and plainclothes officers have been patrolling the transit system since Monday, when scores of commuters in Moscow were killed or injured in the bombings of rush-hour trains at subway stations. Officials would not disclose how many more officers are on patrol.
There have been no known threats against Chicago-area targets in connection with the bombings.
Commuters and CTA employees are reminded to be aware of their surroundings and to report suspicious activity to police.
Marc Magliari, an Amtrak spokesman, said the rail system regularly works with the federal Transportation Security Administration and the Department of Homeland Security to take appropriate security measures on its trains or tracks in response to such situations.
