Rydalmere railway station was located on the former Carlingford line of the Sydney Trains network, which closed on 5 January 2020 for conversion to light rail. The next station to the south was Camellia and to the north was Dundas. A conversion of the Camellia to Carlingford section of the Carlingford railway line to light rail was announced in 2015 as part of the Parramatta Light Rail project. Though originally to run entirely to the south of the Parramatta River, a redesigned second branch of the light rail was announced in 2017. Beginning at Sydney Olympic Park, the line will pass through Rydalmere before joining up with the Carlingford branch at either Rydalmere or Camellia. If the Camellia option is chosen, a new bridge across the river would be constructed between the two suburbs.
