WASHINGTON, D.C. - It was all-aboard for some of the state’s most powerful business leaders and politicians today.

The annual Chamber Train, the state’s largest networking event, headed to the nation’s capital today.

He didn’t take the train, but Gov. Chris Christie will travel to Washington to provide a progress report on Sandy recovery efforts as the event’s keynote speaker.

His expected competition in the upcoming gubernatorial race, Democrat Barbara Buono, boarded the train in New Brunswick.

This is the Chamber of Commerce’s 76th trip. It features a chartered 14-car train filled with 900 of New Jersey’s business and political leaders.

The trip is also known as the "Walk to Washington," as people tend to network as they walk through the cars.
