Explanation:

All employee conditions during the Industrial Revolution of the 19th century were very harsh, America's railroad industry became mostly a freight-hauling industry as opposed to a passenger-carrying industry due to America's size and various population densities. Freight hauling was far more dangerous to railroad workers because they often had to work in between moving cars in order to link freight cars together or unlink them. They also had to ride on the cars in order to manually use the brakes to stop the train. Since railroad employee wages were also high, employers had to economize by spending less on trains and equipment and by hiring fewer employees. Fewer employees resulted in not having enough hands to perform a dangerous task, resulting in "many derailments and collisions"
