Can't find track work info

Hi, does anyone know which api has the trackwork information in it ? I am a Mac developer of a Sydney Trains planner : Download Transporter for Mac | MacUpdate

Hi @kob2040, you can find trackwork information in the trip planner add_info feed - Trip Planner APIs | TfNSW Open Data Hub and Developer Portal

Please read all the technical documentation available to see exactly what is in the feeds and how it’s structured.
