There are downsides to having tracks going through city lands. The tracks take up land that could been used for businesses and they cut a city in half. By adding railroad crossings, you lessen the effects of the tracks in discouraging travel around the city.
Liberty University's 15,000 students would be frequent travelers using these new railroad crossings. Having an easy and safe way to get across the tracks helps the town increase commerce and movement around the city.
Since the students will finally have a safe and easy way to get to local businesses, commerce will increase in the areas surrounding the railroad tracks. The increased commerce creates a productive and happy community.
