Chester Hill station opened on 8 October 1924 when the Main Southern railway line was extended from Regents Park to Cabramatta.

Historically, eastbound services connected Chester Hill to the City Circle via Lidcombe and the Main Suburban railway line.

Between 2013 and 2024, eastbound services from Chester Hill to the City Circle ran only via an alternate route along the Bankstown railway line.

[5] Following the partial closure of the Bankstown railway line for Sydney Metro conversion in 2024, this situation reverted.

Now eastbound services from Chester Hill operate to the City Circle via Lidcombe again, branded as the T3 Liverpool & Inner West Line.
