How did the transcontinental railroad effect the cowboys and cattle men?

Railroads enabled easier and closer access to points to sell cattle. Cowboys didn't have to travel as far to sell their cattle, so cattle that didn't have to travel as far had meat that wasn't as tough and stringy, and cowboys had more time on their hands to be able to help with ranch chores, and weaned calves could stay on the ranches for a little longer because of the shorter distance.
