The trains were delivered in several phases. The phases have different model numbers but an identical appearance. The models numbers include: SP1900, SP1950, KRS991 and 1151. Unless specified, the name SP1900 would apply to describe all the model numbers in this article. Another model, 1141A (MTR CRRC Changchun EMU), is similar in design to the SP1900, but was built by a different manufacturer and has a slightly different appearance. After the rail merger, the KCR logos on the SP1900 EMU were replaced with those of MTR, and a revised route map was introduced in the train interiors.
