No matter how smart modern rail travel is, trains still operate on rails, hence rail track layers will always be in demand. Just as there were when the railroads first opened up America's west. They travel wherever they are needed on the system, from the rail yard to an underground tunnel farther down the line. Plant yards, quarries, sand and gravel pits, and mines may also include rails. This is an entry-level position in the train system that requires no previous work experience. 

A high school graduation, physical strength and coordination, and a strong feeling of duty are usually required to get started. Workers with less seniority might expect to work nights and weekends. You may be exposed to rain, wind, and snow at times, and overtime may be required, especially in an emergency. After all, you are a component of the country's train system. Passenger and cargo safety is dependent on your cautious, consistent labour.
