passage content (partial, as image text):
... thousands of laborers worked each day at a slow pace through difficult mountainous landscape... many different immigrants contributed to building the railroad, including chinese, irish, and german workers.
the two companies intended to connect their rails about halfway between the starting points. however, the u.s. government promised benefits to the company that laid the most railroad. this prompted fierce competition between the two companies. this competition became dangerous when the companies drew closer to one another in the late 1860s. each company began to sabotage the other’s work. they did this using dynamite and other methods to prevent the rival company from laying more rails.
in the end, the two companies connected rails. meeting in 1869 at promontory summit, utah, the final “golden spike” was hammered into the linked railroad. the completed transcontinental railroad allowed people and goods to travel across the united states in only a matter of days.
