Arema

The American Railway Engineering and Maintenance-of-Way Association (AREMA) was formed on 10/1/1997, as the result of a merger of three engineering associations -  the American Railway Bridge and Building Association (ARB&B), the American Railway Engineering Association (AREA) and the Roadmaster's and Maintenance of Way Association (RMWA), along with functions of the Communications and Signals Division of the Association of American Railroads.
