Rail is the mode of choice for bulk commodi ties such as solid mineral fuels (coal, coke), ores and metal waste as well as an important mode for the transport of petroleum prod ucts and fertilisers. Rail freight hubs worldwide are not only fed by railway lines but increasingly also by rail road combined transport.

Railroad directions are used to describe train directions on rail systems. The terms used may be derived from such sources as compass directions, altitude directions, or other directions. However, the railroad directions frequently vary from the actual directions, so that, for example, a "northbound" train may really be headed west over some segments of its trip, or a train going "down" may actually be increasing its elevation. Railroad directions are often specific to system, country, or region
etween 1820 and 1850 some six thousand miles of railways were opened in Britain, mostly as the result of two extraordinary bursts of concentrated investment followed by construction, the little railway "railway mania" of 1837 7 and he gigantic one of 1845 7. In effect, by 1850 the basic English railway network was already more or less in existence.
In the event of a new construction or large scale modification of general railway (except Shinkansen), the following noise levels shall be achieved at 1.2m above the ground in the open air along the railway line and at a position12.5m away in horizontal distance from the center line of the near side track.
The Burry Port and Gwendraeth Valley Railway was a mineral railway company that constructed a railway line in Carmarthenshire, Wales, by conversion of a canal, to connect collieries and limestone pits to the sea at Kidwelly. It extended its network to include Burry Port, Trimsaran and a brickworks at Pwll, later extending to Sandy near Llanelli. For a time the company worked the separate Gwendraeth Valleys Railway. The BP&GVR was notable because of the very low height of some overbridges, a lega
