SMART Transportation Division represents employees on every Class I railroad, as well as employees on many regional and shortline railroads.

SMART TD’s membership is drawn primarily from the operating crafts in the railroad industry and includes conductors, brakemen, switchmen, ground service personnel, locomotive engineers, hostlers and workers in associated crafts. Through experienced representation and its legislative strength, SMART TD has been instrumental in the preservation of Amtrak (the national rail passenger network).
