The T6 Carlingford Line between Clyde and Carlingford is being permanently closed from 5 January 2020. This closure is to allow for the construction of Parramatta light rail between Carlingford and Westmead, which will partially use the corridor.
A new bus route will service the corridor between Carlingford and Parramatta during light rail construction. Route 535 will operate from January 5, 2020 with stops at Carlingford, Telopea, Dundas, Rydalmere, Camellia/Rosehill and Parramatta CBD.
Trams are due to start running along the first part of the route in 2023. When the light rail opens it will provide the same area with a service every seven and a half minutes between 7am and 7pm on weekdays.
