Chapter 1 Introduction
Railway consists of two steel rails
which are held a fixed distance apart upon a road bed. Vehicles, guided and
supported by flanged steel wheels, and connected into trains, are propelled as
a means of transportation.
Within this definition there are many
different forms, such as driving mode, details of the track structure, train
composition, traffic, etc. are all within the category of the term railway.
The railway definition is composed of
three critical factors:
1 It reduced friction to an extent
that let the heavy locomotive not only move itself across the land but have enough
power left over to move a good load at an unprecedented speed.
2 It reduced the cost of a
low-friction railway, making it possible for the railway to penetrate any area
of the country where raw materials were found or people lived and worked.
3 It provided a guideway, eliminating
the limitation of transporting everything in single vehicles. This distributes
the cost of motive power and crew over a number of practical loads.
Railways have usually been built for
economic reasons, but some railways were also constructed as part of their
countrys military establishment. In
many countries railways were constructed to store of raw materials such as forests,
coal deposits, oil fields, iron mine and copper ore.
Railways have built-in degradation,
tracks, rolling stock, and motive power must be maintained and renewed.
Power supply
The
electric locomotive is supplied externally with electric power, either through
an overhead contact line or through a third-rail.
Early
locomotives had a variety of forms. Generally they were designed according to
the current supply mode, so locomotives with a direct current DC supply had
DC motors while alternating current AC supplied locomotives operate with AC
motors. AC can be either single or three phase. While the former requires two
wire supply, one overhead the other being the track, three phase requires three
supply wires. Three phase locomotives therefore had two lines as overhead
supplies, and one as the track.
DC
supplies were either overhead or by means of track level supply, commonly
called the third rail.
Now a
stable electric control system means the motor does not need to match the supply.
This means multi-voltage cross border locomotives are now quite common. Drive
motors are generally DC, but there are more and more 3 phase drive motors.
