Regional rail or commuter rail usually provide a rail service between a central business district and suburbs or other locations that draw large numbers of people on a daily basis. The trains providing such services may be termed commuter trains. The development of commuter rail services has become popular today, with the increased public awareness of congestion, dependence on fossil fuels, and other environmental issues, as well as the rising costs of owning and operating automobiles.
