There will be big train disruptions on the way for Sydney commuters, with services between Epping and Chatswood ceasing at the end of September for a construction project.
From September 30, the line will be closed with trains not running between Epping and Chatswood for at least seven months.
This comes as upgrades are underway with the new Sydney Metro from Rouse Hill.
Hornsby services will start and stop at Central, with passengers who need to go elsewhere on the City Circle line needing to change trains.
Pink buses will also run between Epping and Chatswood, with 120 entering service.
They will shuttle commuters to closed stations on the route, going through Strathfield to the CBD.
