Baldwin Locomotive Works of Philadelphia originally built the brightly painted locomotives in the 1910s and 1920s. They were purchased from United Railways of Yucatan in 1969, disassembled and shipped to a Tampa (Fla.) ship repair dock where they were renovated, bolt by bolt. The passenger cars were fabricated from scratch in the same warehouse where the locomotives were renovated. Originally wood burners, the locomotives were converted and currently are oil burners.
The four locomotives, which hauled both freight and passengers in the Yucatan, were renamed the Walter E. Disney, the Roy O. Disney, the Lilly Belle and the Roger E. Broggie. (Broggie was an Imagineer who also was a train fanatic.)
