Factual error: In the scene where the young Helen Goff is traveling by train with her family, it's obvious that an American engine and coaches have been used, instead of a Queensland Rail locomotive of the era. None of the QR locomotives had flared smokestacks like on the one seen in the movie. The coaches are also incorrect - as far as I know, none of the Queensland Rail wood coaches had clerestory roofs with a set of windows in them like seen in the movie. When Helen looks out the back of the train, it's also obvious that the tracks are spaced at 'standard gauge' (4' 8.5"). They should be closer together, as railways in Queensland are built to 3'6" gauge instead. There is also no such company as the 'Queensland Victoria Railway Co', as marked on the coaches, as all railways in Australia are state owned.
Factual error: When Mrs. Travers arrives at the airport, there's a driver holding a name-card with a Warner Bros. Television logo on it. It's a far more modern version of the logo, however - in fact, the word 'Television' didn't appear in the ribbon across the shield until 1994. (00:10:10)
Factual error: The scene at LAX incorrectly has signage for Trans World Airlines as Trans World Airways.
Factual error: During the cut scene to the Disneyland entrance, modern touch screen ticketing kiosks are visible.
Factual error: During Travers' trip to Disneyland, several aspects of modern Disneyland can still be seen in the background despite filmmakers' attempts to work around them. In 1961, the opening of the park was gated with a chain-link fence and paved with asphalt, the iron gate and pavers seen in the film were added decades later. The planter retaining wall, in front of which Walt is standing, was concrete, not brick, which was added in 1999. There are good pictures for comparison here: http://www.yesterland.com/entrance.html As Walt and Travers board the King Arthur Carrousel, hints of the new Fantasyland that debuted in 1983 can be seen. This expansion changed the theming of Fantasyland behind the castle from Renaissance Faire tents to a Medieval village. The Carrousel was pushed back and the planters at the entrance seen in the film were added. In 1961 the Carrousel was surrounded by little more than a chain-rope. The modern stone village look of Fantasyland can be seen several times in the background as they approach the Carrousel and ride on it, although some signage has been placed in the background to emulate how things would have worked in the 1960s (such as each ride requiring its own cost or ticket to get on) - the 10-cent sign is historically accurate. On the Carrousel itself, the pictures from Sleeping Beauty on the inner core of the ride weren't added until later.
Factual error: On the destination board at Maryborough station, the board shows various towns listed. Vandina is one of them. There is no such town as Vandina, its actually Yandina. In addition, the board is entitled in part- Gold Coast railway. The destinations past Brisbane are not on the old Gold Coast branch, but go inland through Ipswich, Grandchester, and ultimately end at Allora, which is a town just north of Warwick, in southern Queensland.
