For reasons that are somewhat unclear, Thomas and Friends has become a favorite among children (and some adults) with autism. There are theories about its popularity. Some believe that it’s all about the fact that trains line up on a track (and most people with autism enjoy lining objects up). Others think it’s all about the simplicity and repetitive nature of the stories. Whatever the reasons, however, it’s hard to have a child with autism and avoid knowing a great deal about the various types of engines once used to move people and freight around the United Kingdom.

Luckily, the folks at Brio (the company that makes Thomas-related products) have created an impressive line of safe, well-constructed, versatile items that can help your child learn skills, build knowledge, and develop social communication. Even better, Thomas the Tank Engine has become wildly popular among all kinds of people, including train enthusiasts, which means that you can use a child’s interest in Thomas to get involved with a much wider world.
