The National Railway Museum at Port Adelaide has more than 100 exhibits within two huge pavilions and an 1870's heritage listed goods shed.
It represents railway operations from State, Commonwealth and private operators on the three major railway gauges used throughout Australia.

Interactive displays include safe operating practices, the role of women in the railways, and the famous 'Tea and Sugar' train that served railway families on the barren Nullarbor Plain. Activities include exploring the Woodville signal cabin, viewing the model railway, and taking a train ride (included in the entry fee). The Break of Gauge Shop has Thomas the Tank Engine toys and a large range of souvenirs, videos, DVDs and books for sale.

The National Railway Museum is home to the Friends of Thomas the Tank Engine event during the July school holidays. It also caters for celebrations and children's birthday parties.
