Railroads

Why time zones were needed

Due to this lack of time standardization, schedules on the same tracks often could not be coordinated, resulting in collisions.

Time Zones

How Airbrakes Work

The signal is controlled from the automatic brake valve on the lead locomotive by changing the air pressure in the brake pipe. The principle of train air brakes is based on lowering brake pipe pressure to apply the brakes and increasing brake pipe pressure to release the brakes.

Railroad Airbrakes

Transcontinental Railroads

A transcontinental railroad in the United States is any continuous rail line connecting a location on the U.S. Pacific coast with one or more of the railroads of the nation's eastern trunk line rail systems operating between the Missouri or Mississippi Rivers and the U.S. Atlantic coast

Communications

Communication

Telegraph

Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message.

Telephone

A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly.

Electricity

phonograph

Phonograph

A phonograph, in its later forms also called a gramophone or since the 1940s called a record player, or more recently a turntable, is a device for the mechanical and analogue recording and reproduction of sound.

lightbulb

Lightbulb

An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament that is heated until it glows. The filament is enclosed in a glass bulb that is filled with vacuum or inert gas to protect the filament from oxidation.

Alternating Current

Alternating Current (AC) is a type of electrical current, in which the direction of the flow of electrons switches back and forth at regular intervals or cycles. Current flowing in power lines and normal household electricity that comes from a wall outlet is alternating current.

Alternating Current

Locomotives

The union of steam and iron rails produced the railways, a new form of transport which boomed in the later nineteenth century, affecting industry and social life.

New Machinery

Bessemer Process

The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.
