This twin-cylinder locomotive was not heavy enough to break the edge-rails track and solved the problem of adhesion by a cog-wheel using teeth cast on the side of one of the rails.
Thus it was also the first rack railway. This was followed in by the locomotive Puffing Billy built by Christopher Blackett and William Hedley for the Wylam Colliery Railway, the first successful locomotive running by adhesion only. This was accomplished by the distribution of weight between a number of wheels. Puffing Billy is now on display in the Science Museum in London, making it the oldest locomotive in existence.
Stephenson played a pivotal role in the development and widespread adoption of the steam locomotive. His designs considerably improved on the work of the earlier pioneers.
In he built the locomotive Locomotion for the Stockton and Darlington Railway in the north east of England, which became the first public steam railway in the world inalthough it used both horse power and steam power on different runs.
Inhe built the locomotive Rocketwhich entered in and won the Rainhill Trials. This success led to Stephenson establishing his company as the pre-eminent builder of steam locomotives for railways in Great Britain and Ireland, the United States, and much of Europe.
Steam power continued to be the dominant power system in railways around the world for more than a century. Electric power introduced[ edit ] See also: Electric locomotive and Railway electrification system The first known electric locomotive was built in by chemist Robert Davidson of Aberdeen in Scotland, and it was powered by galvanic cells batteries.
Thus it was also the earliest battery electric locomotive.The History Of The Rail Transport (Railway Freight Yards Industry)
Davidson later built a larger locomotive named Galvani, exhibited at the Royal Scottish Society of Arts Exhibition in The seven-ton vehicle had two direct-drive reluctance motorswith fixed electromagnets acting on iron bars attached to a wooden cylinder on each axle, and simple commutators.
It hauled a load of six tons at four miles per hour 6 kilometers per hour for a distance of one and a half miles 2. It was tested on the Edinburgh and Glasgow Railway in September of the following year, but the limited power from batteries prevented its general use.
It was destroyed by railway workers, who saw it as a threat to their job security. The world's first electric tram line, Gross-Lichterfelde Tramwayopened in Lichterfelde near BerlinGermany, in It was built by Siemens.
The tram ran on Volt DC, which was supplied by running rails. In the track was equipped with an overhead wire and the line was extended to Berlin-Lichterfelde West station. The railway is still operational, thus making it the oldest operational electric railway in the world. It was the first tram line in the world in regular service powered from an overhead line. Five years later, in the U. Electricity quickly became the power supply of choice for subways, abetted by the Sprague's invention of multiple-unit train control in By the early s most street railways were electrified.
Passengers wait to board a tube train on the London Underground in the early s The London Undergroundthe world's oldest underground railway, opened inand it began operating electric services using a fourth rail system in on the City and South London Railwaynow part of the London Underground Northern line.
This was the first major railway to use electric traction. The world's first deep-level electric railway, it runs from the City of Londonunder the River Thamesto Stockwell in south London. Using experience he had gained while working for Jean Heilmann on steam-electric locomotive designs, Brown observed that three-phase motors had a higher power-to-weight ratio than DC motors and, because of the absence of a commutatorwere simpler to manufacture and maintain. A prototype of a Ganz AC electric locomotive in Valtellina, Italy, Italian railways were the first in the world to introduce electric traction for the entire length of a main line rather than a short section.
The company conducted trials at AC 50 HZ, and established it as a standard. Following SNCF's successful trials, 50 HZ, now also called industrial frequency was adopted as standard for main-lines across the world. Sulzer had been manufacturing diesel engines since The Prussian State Railways ordered a diesel locomotive from the company in The world's first diesel-powered locomotive was operated in the summer of on the Winterthur—Romanshorn railway in Switzerland, but was not a commercial success.
The first regular use of diesel—electric locomotives was in switching shunter applications. General Electric produced several small switching locomotives in the s the famous " tonner " switcher was introduced in Westinghouse Electric and Baldwin collaborated to build switching locomotives starting in Inthe Canadian National Railways became the first North American railway to use diesels in mainline service with two units, andfrom Westinghouse. High-speed rail Although high-speed steam and diesel services were started before the s in Europe, they were not very successful.
The construction of many of these lines has resulted in the dramatic decline of short haul flights and automotive traffic between connected cities, such as the London—Paris—Brussels corridor, Madrid—Barcelona, Milan—Rome—Naples, as well as many other major lines. While high-speed rail is most often designed for passenger travel, some high-speed systems also offer freight service.
Train A train is a connected series of rail vehicles that move along the track. Propulsion for the train is provided by a separate locomotive or from individual motors in self-propelled multiple units.
Most trains carry a revenue load, although non-revenue cars exist for the railway's own use, such as for maintenance-of-way purposes. The engine driver engineer in North America controls the locomotive or other power cars, although people movers and some rapid transits are under automatic control.
This involves one or more powered vehicles being located at the front of the train, providing sufficient tractive force to haul the weight of the full train. This arrangement remains dominant for freight trains and is often used for passenger trains. A push—pull train has the end passenger car equipped with a driver's cab so that the engine driver can remotely control the locomotive. This allows one of the locomotive-hauled train's drawbacks to be removed, since the locomotive need not be moved to the front of the train each time the train changes direction.
A railroad car is a vehicle used for the haulage of either passengers or freight. A multiple unit has powered wheels throughout the whole train.
High-speed rail - Wikipedia
These are used for rapid transit and tram systems, as well as many both short- and long-haul passenger trains. A railcar is a single, self-powered car, and may be electrically-propelled or powered by a diesel engine. Multiple units have a driver's cab at each end of the unit, and were developed following the ability to build electric motors and engines small enough to fit under the coach.
There are only a few freight multiple units, most of which are high-speed post trains. A RegioSwinger multiple unit of the Croatian Railways Steam locomotives are locomotives with a steam engine that provides adhesion. Coalpetroleumor wood is burned in a fireboxboiling water in the boiler to create pressurized steam. The steam travels through the smokebox before leaving via the chimney or smoke stack.
In the process, it powers a piston that transmits power directly through a connecting rod US: Steam locomotives have been phased out in most parts of the world for economical and safety reasons, although many are preserved in working order by heritage railways.
Electric locomotives draw power from a stationary source via an overhead wire or third rail. Some also or instead use a battery. In locomotives that are powered by high voltage alternating currenta transformer in the locomotive converts the high voltage, low current power to low voltage, high current used in the traction motors that power the wheels.

Modern locomotives may use three-phase AC induction motors or direct current motors. Under certain conditions, electric locomotives are the most powerful traction. High-speed aspirations[ edit ] After the breakthrough of electric railroads, it was clearly the infrastructure — especially the cost of it — which hampered the introduction of high-speed rail.
Several disasters happened — derailments, head-on collisions on single-track lines, collisions with road traffic at grade crossings, etc. The physical laws were well-known, i. Wellington Adams proposed an air-line from Chicago to St.
Miller had greater ambitions. High-speed interurbans[ edit ] In the US, some of the interurbans i. Several high-speed rail technologies have their origin in the interurban field.
In — 30 years before the conventional railways started to streamline their trains — the officials of the Louisiana Purchase Exposition organized the Electric Railway Test Commission to conduct a series of tests to develop a carbody design that would reduce wind resistance at high speeds.
A long series of tests was carried. Louis Car Company built a railcar for the traction magnate Henry E. Brill and others pioneered lightweight constructions, use of aluminium alloys, and low-level bogies which could operate smoothly at extremely high speeds on rough interurban tracks. Westinghouse and General Electric designed motors compact enough to be mounted on the bogies.
The Red Devils weighed only 22 tons though they could seat 44 passengers.
