Up And Down (rail Directions)
Rail 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. These directions are often specific to system, country, or region. Radial directions Many rail systems use the concept of a centre (usually a major city) to define rail directions. Up and down In British practice, railway directions are usually described as "up" and "down", with "up" being towards a major location. This convention is applied not only to the trains and the tracks, but also to items of lineside equipment and to areas near a track. Since British trains run on the left, the "up" side of a line is usually on the left when proceeding in the "up" direction. On most of the network, "up" is the direction towards London. In most of Scotland, with the exception of the West and East Coast Main Lines, and the Borders Railway, "up" is towards Edinburgh. The Valley Lines network around Cardiff h ...

Centre (geometry)
In geometry, a centre (English in the Commonwealth of Nations, Commonwealth English) or center (American English) () of an shape, object is a point (geometry), point in some sense in the middle of the object. According to the specific definition of centre taken into consideration, an object might have no centre. If geometry is regarded as the study of isometry groups, then a centre is a fixed point of all the isometries that move the object onto itself. Circles, spheres, and segments The centre of a circle is the point equidistant from the points on the edge. Similarly the centre of a sphere is the point equidistant from the points on the surface, and the centre of a line segment is the midpoint of the two ends. Symmetric objects For objects with several symmetries, the centre of symmetry is the point left unchanged by the symmetric actions. So the centre of a square (geometry), square, rectangle, rhombus or parallelogram is where the diagonals intersect, this is (among other ...

Flying Scotsman (train)
The ''Flying Scotsman'' is an express passenger train service that operates between Edinburgh and London, the capitals of Scotland and England, respectively, via the East Coast Main Line. The service began in 1862 as the ''Special Scotch Express'' until it was officially adopted in 1924. It is currently operated by London North Eastern Railway. History The East Coast Main Line over which the ''Flying Scotsman'' service runs was built in the 19th century by many small railway companies, but mergers and acquisitions led to only three companies controlling the route; the North British Railway (NBR), the North Eastern Railway (NER) and the Great Northern Railway (GNR). In 1860 the three companies established the East Coast Joint Stock for through services using common vehicles, and it is from this agreement that the ''Flying Scotsman'' came about. Operation The first ''Special Scotch Express'' ran in 1862, with simultaneous departures at 10:00 from the GNR's London Ki ...
