The Sydney Trains A & B sets, also referred to as the Waratah trains, are classes of electric multiple units that currently operate on the Sydney Trains network. Based on the M sets, the Waratahs were manufactured by a joint consortium between CRRC and Downer Rail, with initial construction taking place overseas in Changchun before final assembly at Downer Rail's Cardiff Locomotive Workshops. The sets were named after the Waratah flower, which is the state's floral emblem.

The initial order for 78 A sets was the largest rolling stock order in Australia's history. These 624 A set carriages make up around half of the Sydney Trains fleet and replaced two-thirds of the 498 S set carriages. Delivery commenced in July 2011 and was completed in June 2014.
An order for 24 additional trains with updated technology and a lightly revised design was placed in December 2016. These are classified as B sets, or colloquially as Waratah Series 2 trains. The delivery of the first order of sets began in September 2018 and was completed in June 2019, while a second and final order of a further 17 sets began in September 2020 and was completed in June 2021.
