Emerson Zooline Railroad
ALL ABOARD! The Emerson Zooline Railroad offers a 20-minute narrated tour weaving through tunnels and past favorite animal exhibits on a 1½-mile round trip. One of the Zoo's most popular attractions, the Zooline Railroad has transported more than 39 million visitors since 1963. The railroad operates year-round, weather permitting.
