Explain why the railroads were not built in a straight line from east to west.

There is a lot of reason why railroads from east to west were not built straight. Mountains are the number 1 reason why. Since there are a lot of mountains in between east and west, it would be hard for them to create a straighter railroad. Lakes, rivers and any other circumstances also affected this construction. This railroad also served as the link from each places for their trading. That’s why it was not built straight since it needs to connect from different places for their trading reason.
