This site should help you with the materials that were used.
1) What are the materials the workers used to construct the first transcontinental railroad?
2) What are the materials in the railroad?
3) What are the long-term and short-term causes of the transcontinental railroad (if there are any short-term causes)?
I WILL APPRECIATE YOUR HELP :)
