March 31 (Reuters) - The International Association of Machinists and Aerospace Workers $(IAM.AU)$ said on Monday it had secured a tentative deal that covers about 4,900 freight rail workers with the National Carriers' Conference Committee (NCCC), which represents U.S. freight railroads.

The agreement follows a recent wave of agreements and ratifications in the U.S. railroad industry after the Joe Biden administration had called for better benefits for freight railroad workers.

An electronic ratification vote will take place between April 25 and April 30, IAM said.

The tentative agreement covers IAM District 19 members at BNSF, Norfolk Southern NSC.N, Canadian National CNR.TO, Belt Railway, Terminal Rail, Consolidated Rail, Indiana Harbor Belt, New Orleans Public Belt, and Palmetto Railways.
