Animator Walt Disney created the concept of Disneyland due to his love for trains. Walt Disney incisions a park in Anaheim with steam trains and themed rides.
The train lines in the park were named Carolwood Pacific, akin to Union Pacific.
The first Mickey Mouse animation had a cartoon train as part of the feature. The museum had original sketches of the train on display.
This special exhibit on Disneyland was displayed at the Napa History Museum.
