What railroad tycoon was known for consolidating railroads?

a. Fisk

b. Grant

c. Vanderbilt

d. Carnegie

Cornelius Vanderbilt. He was a great during and after the Industrial Revolution. He made a great amount of money with his railroads.

Andrew Carnegie - he was known for his steel works.

Though for whoever made this question it would have good to make one of the answer choices Rockefeller another great during those times. For he was known to work with Vanderbilt at one time.

The other choices I have no voice on them.
