Rail transport operations - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-09) |
 | | A rail transport or railroad system is a complex synergy of components which may be classified into two groups: extrinsic factors and intrinsic factors. |
 | | Rail transport systems are built into the landscape, including both the physical geography (hills, valleys, etc) and the human geography (location of settlements). |
 | | Rail transport systems are often used for purposes for which they were not designed, but have evolved into due to changes in the human geography. |
