With more than 50 people already confirmed dead from yesterday's terrorist bombings in London, police are expecting to find additional victims. They still aren't getting near some damaged subway cars in a tunnel that is considered unsafe.
The Homeland Security Department in the US responded to the attacks by raising the terror threat level for mass transit agencies across the country as a precaution.
The threat level was elevated to orange for railways, subways and city bus systems.
Chatham Area Transit drivers are on alert for anything suspicious. While the Homeland Security Department says there is no credible evidence of attacks planned against the US, CAT officials say they take this, and every warning, very seriously.
"We routinely and periodically train to ensure that our bus operators are trained to observe and report suspicious activities and suspicious people," said CAT deputy transportation director John Broderick.
"I don't know if I feel safer or not," rider Bob Preston said. "It's hard to judge because we don't know what they're thinking or what they're going to do, but I absolutely think we need some heightened alert."
The orange alert applies only to transit systems. However, the rest of the country remains at the yellow alert level.
