The “Occupy Wall Street” movement has been winning support from many quarters, but the latest comes from the world of transportation.

On Tuesday, the Amalgamated Transit Union, with more than 190,000 members in the United States and Canada, pledged its support.

Union officials said members of three New York City locals were at Zuccotti Park in Lower Manhattan Monday and plan to attend a march on Wednesday. The union and locals plan to donate food and other supplies and to participate in protests in New York and across the country, officials said.

The union is the parent of Local 689, which represents most Metro employees in the Washington region.

“While we battle it out day after day, month after month, the millionaires and billionaires on Wall Street sit by – untouched – and lecture us on the level of our sacrifice,” Larry Hanley, ATU’s president, said in a statement.

“Working Americans have sacrificed too much already. Transit riders have paid with record fare increases and service cuts.  How dare they demand that we coddle the rich while poor people are losing their benefits and millions are becoming poor?”
