 | | A railway (or railroad) track consists of two parallel rail tracks, formerly of iron now of steel, generally mounted upon cross beams (termed "sleepers" (Commonwealth) or "railroad ties" (U.S.)) of timber, concrete or steel. |
 | | Most rail systems, including urban rapid transit (metro/subway) systems, are highly subsidised and have never or rarely been profitable; however, their indirect benefits are often great. |
 | | Similarly, passenger rail in all countries is dependent on government subsidies. |
