The Houston Area Live Steamers group offers free train rides in Houston every third Saturday of the month:
Public Run Days are scheduled for the 3rd Saturday of the month, March through November at Zube Park. During this time we offer free train rides to the community. Here is a map with directions to the park.
All ages are welcome to ride. We have two club diesel engines that normally run the passenger trains but many times you will find a steam engine also running. We have specially designed cars for the young and the young at heart who enjoy hearing the clickety-clack of the rails. A newly designed car for wheelchairs will be online soon for those needing special assistance.
Special thanks to the Kids Activity Queen for pointing me to this resource.
