FAIRFIELD - Metro-North is the second busiest commuter rail road in the United States. So whenever there is a major attack, like the one Tuesday in Brussels, Metro-North's parent company, Metropolitan Transit Authority, acts swiftly.
By midmorning the MTA announced it was adding more police on trains and in stations in light of the Brussels bombings.
"There was a little bit more security," said Sandra Lee of Easton, who rode a Metro-North train from New York's Grand Central Terminal to Fairfield Tuesday afternoon. "You could see there were even more horses around. There were more fire trucks outside of Grand Central Station, as well."
Sal Garibay, a frequent train commuter from Fairfield, said he definitely notices that "people get a little bit tense when scares like this and horrible acts happen."
"It just makes you bit more nervous than you normally would be," said Monica Nieves, of Guilford, who was traveling to Baltimore by train Tuesday.
Many rail commuters subscribe to the theory that you cannot live your life in fear. And for some, traveling right after a major event makes them feel more secure.
"I know that when I get to Grand Central there's going to be a huge police presence just like after 9/11," said Betsy Borkowski, of East Lyme. "I was in New York on 9/11. And, you know, Grand Central was like an armed camp."
Like her, most were OK with traveling today. But, as we go about our business, one woman suggests we all need to be prayerful.
"We have to thank God that we live in America," said Tanya Redd, of New Haven. "A lot of people don't like America. But, guess what? It's one of the greatest countries."
As if this wasn't concern enough for commuters out of Grand Central, there was also a restaurant fire in that train station that sent smoke billowing from inside, making some wonder if another attack had been perpetrated.
