Completed with a Golden Spike ceremony at Promontory Summit, Utah on May 10th, 1869, the First Transcontinental Railroad linked California with the existing rail network of the eastern United States.
Well not only was it a major logistics challenge to manufacture and move everything necessary to build it, there was weather, geographicle featurs like mountains and river that had to be dealt with and raids by hostile indians and outlaws. All of the workers needed to be fed, medical care provided, mobile ;iving accomodations and so on. It was a major undertaking especially for that time in history.
The Romans used something called an aqueduct to bring in water from lakes to their city. Aqueducts are tubes that go through mountains are elevated above valleys with a very slight angle downward then entire time. The downward slope ensures that the water will flow without the need for any sort of pump.
Railroad
No. The English have nowhere to build a transcontinental railroad; they are on an island. The US was the first to begin such a railroad - aptly named the First Trascontinental Railroad - and the Russians soon followed with the Trans-Siberian Railway.
The railroad needed builders, and those builders lived in new towns along the railroad. Settlers moved with the railroad because they could get lots of land and still have access to manufactured goods from the East because the railroad allowed for the transportation of those goods.

It was to complete the transcontinental railroad by going around the Rocky Mountains to the south instead of over them.
The acquisition of the southern parts of Arizona and New Mexico (known as the Gadsden Purchase) was mainly due to the fact that the United States was trying to connect the East and West coasts by railroad. The Rocky Mountains made this difficult, and railroad companies pressured the government to buy the Gadsden Purchase from Mexico to build a railroad south of the Rocky Mountains. Note: The first intercontinental railroad was actually built through the Rocky Mountains, not south of it. I'm not sure why, if anyone would like to add on to this answer, feel free.
The transcontinental railroad crossed the Rocky Mountains and the Sierra Nevada mountain ranges. These ranges presented significant challenges to railroad construction due to their rugged terrain and elevation.
