Trax is the commuter rail system in Salt Lake City. It begins at the Commuter Hub downtown and has numerous stops including the EnergySolutions Arena, Temple Square, and downtown main street. The line runs throughout Salt Lake all the way down to Sandy. There is also a branch up to the University of Utah. It was a very fun and easy way to get around Salt Lake! They even have a free fare zone in which all riding is free. The trains are clean, and heated/air conditioned and run every 15 minutes. They recently introduced the tap on tap off system in which credit or debit cards can be tapped on the electronic ticketing system and it automatically calculates the correct fare to charge. Tickets are on the honor system but they have random checks for them. Some tickets bought for Trax will also work on the bus system and vice versa. Check their website for schedules and route maps.
