I am making a prediction that TfNSW will soon be making an announcement regarding extension of the Northwest Rail-link to St Leonards, by quadruplicating tracks between Chatswood and St Leonards.
This prediction comes from digging into the NWRL OTS (Operations, Trains, Systems) contract documents. The project deed, on page 210-212 outlines the process by which modification to the NWRL project can proceed, namely:
1. TfNSW requests a modification.
2. "OpCo" (the winner of the OTS contract) must provide a modification impact proposal "as soon as practicable" after receiving the request. This impact proposal must include details such as costs, timing, approvals required and operational impact.
3. TfNSW then has "(blank) business days" to decide whether to accept/reject the proposal.
