Sydney train delays LIVE updates: Industrial action continues for rest of working week, multiple services cancelled ahead of peak commute

Sydney commuters were experiencing delays of about 20 minutes on all lines across the rail network at 6.30am on Thursday, which is expected to worsen throughout the day.
New figures reveal the extent of the chaos on Wednesday, showing that 1913 services were cancelled, and more than 95 per cent of trains delayed or cancelled. Fewer than 5 per cent of trains arrived within five minutes of their operated timetable.

With the chaos extending into a second day, Premier Chris Minns has returned from holidays and is expected to address the media this morning.
The T4 Eastern Suburbs and Illawarra line was the worst affected on Wednesday with delays reaching almost five hours.
However, some workers completed maintenance on critical infrastructure at Bondi Junction overnight, which has allowed equipment to be certified. As a result, delays will be less severe on Thursday on the T4 line, although it set to be affected by flow-on impacts from delays and cancellations on other lines across the city.
A ban by the Electrical Trades Union on locking and unlocking padlocks has meant that maintenance at Homebush station was not completed for a second night. The incomplete works at Homebush will again cause severe disruptions to the T1, T2, T3 and T8 lines.
Work on maintenance at Gosford which was meant to start at midday on Wednesday also remains incomplete, which will cause significant disruptions to intercity trains on the Newcastle and Central Coast line.
