It is located on 2501 South Eden Road, near the intersection with Shiloh Boulevard.

As of 2018, Zion is the 185th busiest of Metra's 236 non-downtown stations, with an average of 110 weekday boardings.

It also serves as a stop for passengers who visit Illinois Beach State Park.

Many trains on the Union Pacific North Line do not serve Zion.

This limited rail service makes this station an impractical method of reaching Chicago during off-peak hours.
