The subway is now fully open beneath 42nd St., a day after Monday's pipe bomb blast. There is no visible sign of the explosion, and to many riders, it's as if nothing happened. NY1 Transit Reporter Jose Martinez filed the following report.

It was back to business Tuesday inside the city's busiest subway hub, a day after a bungled suicide bombing.

"This is New York: We move on, we get on with our lives," one woman said.

Commuter: Honestly, it didn't affect me at all. I didn't even think about it on the train this morning.

Martinez: Why is that?

Commuter: Because it's part of being a New Yorker.

The long passageway linking the Times Square and Port Authority subway stations reopened at 3 a.m. Tuesday, less than 24 hours after Akayed Ullah's pipe bomb went off during the Monday morning rush, injuring five people, plus himself.

The removal of barriers to the crime scene allowed riders to once again walk from the A, C, and E lines beneath Eighth Avenue to the nine lines at the other end of the corridor under Times Square.

"I take it every day, and it's your lifeline to work," one subway rider said.

There were no damaged subway tiles or any other visible signs of the explosion. Commuters did see an increased police presence, from the turnstiles, to the mezzanines, to the platforms.

But even as Police Commissioner James O'Neill tried to assure riders that the vast transit system is secure, a few people NY1 spoke to acknowledged they were not totally at ease.

"I had some jitters this morning. Yeah, after all that happened yesterday morning," one man said.

Among those commuters moving around without much thought to what happened Monday was former Homeland Security Secretary Jeh Johnson, a self-proclaimed big fan of mass transit.

"I do not discourage people from riding the subways, taking public transportation," Johnson said. "But be aware, be vigilant. If you see something, say something."

A mantra by now as familiar to riders as, "This is New York: We move on."
