Monday: New substation for North Shore Line to increased train frequencies
Approval has been given for a new substation South of Lindfield Station to handle increased train frequencies on the Upper North Shore Line. The line currently has 15 trains per hour in the AM peak North of Chatswood, but the government plans to boost this to 20 trains per hour once the North West Rail Link opens in 2019. This will require additional electricity to power the extra trains on that section of the network. Construction is expected to be completed in 2016.
