Located about 16 miles from downtown this museum is located on about 130 acres filled with trains, buses, cars, airplanes and even a boat. There is plenty here for everyone in the family to enjoy. Open year round (train may not operate during in-climate weather). There are exhibits both inside and out so bring sunscreen, wear good shoes and if you have smaller children a stroller as there is a lot of walking. There are 2 entrances to the museum and you can purchase admission in either the Orthwein center or the Barrett station depot. 
We began our visit in the Orthwein education and visitor center. Here you will find the creation station, cafe, gift shop and a collection of horse drawn carriages. They are also display cases that house ways transportation has played a part in our lives from food to entertainment. In a few of the cases you can see replicas of cars from famous movies.
Just outside they have the miniature train station, handcars and cute little butterfly garden. The train runs about 3 times per hour and takes 2 trips around the track each time. You ride past old trains, buses and planes. The scenery along the way is beautiful.
If you head up the hill you will find the Barrett station depot and the Earl C. Lindburg automobile building. Inside the Barrett station there is an small train display and train artifacts. The automobile building houses some of Americas first cars as well as classic cars.
Just beyond this area you will find the train yard. My oldest favorite part was getting to go inside some of the trains. There is even an original man-made tunnel. There are different types of trains for the kids to explore inside. Up towards Roberts pavilion you can ride the trolley car.
Through the grounds kids can go on a letter hunt to solve a secret message from Owney the dog. After they solve the message they can choose from free admission on a future visit, 20% off in the gift shop or free popcorn in the cafe. They also have a Creative corner, a fun play area for younger kids but unfortunately it was closed during our visit. They also have a cafe with kid friendly snacks and even Ted Drews ice cream.
Our family had a great time and my kids are already asking to go back again. I have all girls so this is definitely not just for boys. The big trains may be unsafe for toddlers or babies but the creative corner is perfect for that age group and the train is great for everyone!
