Short answer rocks.

That being said railroad track ballast is the cover for the subgrade. Ballast has several functions:

* It enables water to drain from the track

* It assists in helping control the thermal expansion of continues welded rail * As a train passes the rails it supports the train * it distributes the weight of the train from the track structure to the subgrade * maintains a smooth running surface for the train to run on

As ballast becomes contaminated with other materials it looses its ability to do some or all of these jobs.

• You could travel first class across the country in four days.
• Only parts of the Transcontinental Railroad are in use today.
• The Central Pacific had to blast 19 tunnels through the Sierra Nevada.
• Before the railroad, to get to California from the east coast by boat took about 190 days.
• It took the work of thousands of men to build the Transcontinental Railroad.
• The entire project of the building of the railroad costed hundreds of millions of dollars. And that was the cost in the nineteenth century who knows what it could cost now. Maybe, billions, or even trillions of dollars! two thirds of the workers were Asian the other was American and Irish.

Locating a suitable path was one hurdle, as the Rockies and other western mountain ranges prevented a low-elevation direct route. When the Mexican Cession failed to provide a southerly route, the Gadsden Purchase (1853) provided terrain at least amenable to the limitations of railroad construction of the day. Later technologies enabled more northerly routes through the mountain passes.

This refers to the 10th of May in 1869 when, at Promontory Summit, Utah, the last spike for the "completion" of the transcontinental railroad was driven. The track was in fact not complete due to the fact that cargo and passengers had to be ferried across the Missouri river between Council Bluffs, Iowa and Omaha, Nebraska. (The two burgs.) A train from Ogden, Utah brought the band from Fort Douglas that played for the celebration at Promontory Summit.

There is no "clickety-clack" on continuous welded rail (CWR). Continuous welded rail is layed in 1320' lengths (a quarter mile). Every quarter mile, one weld is required to bond these two ribbons together, on and on it goes. As far as buckling goes, you're on the right track (pun intended). Expansion, contraction and compression are the three major factors that keep me employed as a railroad worker. In high temperatures, we'll get "kinks" in the track that (I have seen) throw the tracks out of alignment up to 3 feet within a 50-foot distance. The rail looks like a piece of spaghetti. In the winter when the steel contracts, the rail will pop like a cannon and leave up to a 3" to 16" gap. Rail anchors help signifigantly reduce these effects. Anchors are the reason you don't see many "buckles" or rail breaks.

In an ideal world, the air temperature is measured over an extended period of time. Given the temperature range, the track will expand a predetermined amount and will retract a predetermined amount. The whole system of anchors, ballast(rocks) and ties prevents the track from buckling. The idea is that an anchor has a set amount that it will hold, the tie has a set amount it will hold, and the ballast surrounding the tie will hold a set amount. By adding up the retaining force of anchors, ties, and ballast, new rail is stretched or heated to the point where track buckles should not occur.

That being said, there there are many factors which can affect the holding force of the track. Including abnormally high or low temperatures, human error, train braking, age of anchors, condition of ties, etc., etc.

The Transcontinental Railroad created a nationwide transportation network that united the United States. This network replaced the wagon trains of previous decades which became useless. It allowed for the transportation of larger quantities of goods over longer distances. This was especially helpful for the industrial north at the time.

While the nation was still divided due to the Civil War, the transcontinental railroad helped unify the nation, eventually making it a super power. Commerce increased between the states allowing over 50 million dollars worth of cargo to be shipped every year from 1869-1879. Goods from Asia and raw materials from the West were shipped to the East faster than ever. The West began to catch up with the Eastern way of life as many more people could now move west and the products of the manufacturing boom were shipped to the West.

In 1862 Congress passed the Pacific Railway Act, which designated the 32nd parallel as the initial transcontinental route and gave huge grants of lands for rights-of-way. The act was an effort to aid in the construction of a railroad and telegraph line from the Missouri River to the Pacific Ocean and to secure the use of that line by the government.
