[3] In preparation for the opening of Hong Kong Disneyland on 12 September, the line started operating on 1 August 2005.

The rolling stock is distinctive on account of its Mickey Mouse windows, interior couch seating, and Disneyland figurines displayed in the carriages.

Bronze statues of well-known Disney characters, such as Mickey Mouse and Donald Duck, are included inside of the trains, and the windows are shaped like Mickey Mouse's head, instead of the rounded rectangles found on trains of other lines.

However, unlike the South Island line, the operator's cab area has been retained, visible through glass windows at each end of the train.

This contrast in design was done to make passengers feel like they are travelling through time between the fantasy world of the Disneyland Resort and the rest of the city.
