In 1979, the centre terminating track was converted to a bi-directional main line with the platform face on the eastern side fenced off.

The above ground upgrades were completed on 14 April 2007, while the underground concourse and platforms were opened on 23 February 2009 in conjunction with the new line.

[9][10] To the north of the station, an additional track was laid as part of the Northern Sydney Freight Corridor project opening in June 2016.

[13] As a result, the Northern line reverted to operating from Hornsby to Central via Strathfield, and was later designated its own route T9 in April 2019.

On 26 May 2019, the underground concourse and platforms reopened and serviced the new Metro North West Line, operating between Chatswood and Tallawong.

The track for the down line was kept in case access to the Sydney Metro tunnels was required by maintenance vehicles.
