Commuter rail in North America

Commuter rail services in Canada, Costa Rica, Cuba, Mexico, Panama and the United States provide common carrier passenger transportation along railway tracks, with scheduled service on fixed routes on a non-reservation basis, primarily for short-distance (local) travel between a central business district and adjacent suburbs and regional travel between cities of a conurbation. It does not include rapid transit or light rail service.
