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.
