The early railroads established "polelines" to carry telegraph wires and electricity alongside the railroad tracks. These looked like what are called telephone poles today, but could have large "crossarms" at the top to carry many wires. These began with just 2 or 4 wires for telegrph use, which later had 2 wires for electricity added. As technology advanced, more wires were added to control trains and send other messages along the lines.

Is electricity variable or fixed?
Electricity is the flow of electrons along a conductor.
In what way the railroad important in Edison's early life?
He worked on the railroad from about age 12 selling newspapers to passengers along the Grand Trunk Railroad line. Because of scarlet fever he was nearly deaf, but his access to news bulletins teletype to the station office each day gave him the idea to publish his own small newspaper. It was a hit and it was the first of his many ideas. He also used his access to the railroad to conduct chemical experiments in a small lab he set up in a baggage car. During one of his experiments the car caught fire and he was kicked off the train. This forced him to sell his papers in the stations.
What is the thick wire called which goes along the electricity?
as far as i know it doesent have a name!!
What are 3 function examples of resistor?
A resistor is really anything that uses electricity along an electric circuit, for example a light bulb, a computer, a radio, etc.
A Generator uses wires and what to create electricity?
Hey there! Great question! So, let's dive into the magical world of generators and electricity. Okay, imagine this: you've got this powerhouse of a machine called a generator. It's like the MVP of the electricity game. Now, to work its magic, a generator needs a couple of key ingredients: wires and motion. Yup, you heard me right! Wires are like the highways that carry the electricity, and motion is the spark that gets everything going. Picture this scenario from my own life: back in the day when I was a teenager, I used to help out at my uncle's farm. We had this old-school generator that we'd fire up every morning. Now, this beast wasn't powered by some fancy fuel; it ran on the good ol' sweat and muscle of our trusty farm animals. We'd hitch up the horses, and as they trotted along, they'd turn a wheel connected to the generator. That motion, combined with the wires inside, would churn out electricity to power up the whole farm. It was like witnessing pure magic! So, long story short, a generator uses wires to conduct the electricity and motion to kick-start the whole process. It's a beautiful dance of science and engineering that keeps the lights on and the world humming along. Hope that clears things up for you!
Why did railroads and the telegraph expand together?
because telegraph wires were poles along the railroad tracks
Does hydrogen ions conduct electricity?
Hydrogen ions formed by dissociation in water, liquid ammonia, or other polar solvents can indeed conduct electricity, along withe their counterions.
What did the transcontinental railroads use their zone of indemnity lands to prevent?
Either: a) judicial actions against the railroad b) military confiscation of lands for forts c) state taxation of railroad waxed fat d) sale if federal land along the right-of-way e) homesteading along the railroad
How did people identify the Underground Railroads?
The Underground Railroad was not an actual railroad, but a series of "safe houses" that escaped slaves would travel along the way to the North or Canada. Houses that were part of the underground railroad were often marked by a quilt or lanterns, that only railroad guides, or "conductors", would know.
What is having the ability to conduct electricity or heat?
Metals are good conductors of heat and electricity.The metal conduct electricity because they have unbound electrons (or valence electrons) that can conduct the electricity as the electrons can move. Similarly, they conduct heat because the electrons are free to vibrate which causes neighbouring electrons to vibrate and so on along the entire piece of metal. These vibrations cause the metal to conduct the heat.Graphite, a type of carbon, is also a good conductor of electricity. Graphite is soot.
Did the north have more railroad track than the south?
Yes, the north had more railroad tracks then the South. This is because the North needed the railroads to connect the cities with the other cities and small towns. The North also needed more railroad tracks because the North was in charge of transporting goods that the South grew. Since the North had more railroads then the South, the North had an advantage when the Civil war came along because they could transport troops guicker.
What were three businesses that opened in towns along railroad tracks?
In the early days of railroads towns actually started along side the rails. There would have been hotels, stores, banks and other types of business that people would have used in their daily lives.
What role did the US government play in the expansion of railroads during the late 1800s?
The government gave the railroads massive concessions. In many areas, they gave the companies land grants of one-half of all land within 10 miles of new tracks. They gave the railroads business with mail and freight. They gave the railroads rights to do business in select areas. In addition, towns often gave the railroads free land for stations and switchyards.
What has the author Thomas S Ridgway written?

What railroads were in the old West?
there things that help you get along
Who is responsible for the weeds along the railroad tracks and along N.M. highways?
Whoever owns the property. If it's railroad property, the railroad is responsible. If it is highway property, it can be the state's responsibility.
Does pure water contain only H2O molecules?
No, it contains H2O molecules along with OH- and H3O+ions from self-ionization. This is why water can still conduct some electricity.
