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.
The Zooline Railroad is ADA accessible. Passengers in wheelchairs have a large area on the train car, with fold down seats for companions. The Zoo has also added ramps with lower slopes.
