Railways depend on third party providers to transport crew—mainly engineers and conductors—from train to train. This may seem odd to those who might wonder, why don’t the crew members just get on another train? The answer lies in the fact that the limited infrastructure for freight rail transportation is already overextended: tracks that should handle 10 trips per day handle 40. The freight routes are also fairly short, 150 to 250 miles, and trains and crews are scheduled to the limit.
