There will be additional trains between 06.00 and 07.30 as well as 14.30 to 16.00 to help customers out during rush hour.
It’s the same schedule that worked during the lockdown and the height of the Delta eruption.
There are already more than 250 Sydney Trains employees who have tested positive for COVID-19.
“Yesterday, 73 people tested positive on Sydney trains, and we had 76 as close contacts, so already it’s really, really bad,” said Alex Classens of Sydney Trains.
“You can imagine what it will be like in the next few days when the test comes online again and more people are being tested.
“It’s going to go through the roof and get crazy.”
The traffic authorities have registered a reduced number of commuters on the trains.
“The numbers have dropped by about 17 per cent compared to this time last year, remember it was the northern beaches,” said Sydney Trains CEO Howard Collins.
“It makes sense to match supply and demand.”
By running fewer services, the transportation system will keep a group of the workforce in reserve.
While buses, trams and ferries remain a regular timetable, authorities have warned that timetables could be changed.
“They can change faster, do not be surprised if a bus area changes to a Saturday or Sunday service, as we see that this affects staff in many areas,” Mr Collins said.
A close contact is now defined as a household contact or someone who has spent more than four hours with a confirmed case.
Close contacts must still be isolated for seven days from the date of their exposure.
The strangest traffic rules in 2021
An asymptomatic close contact should take a rapid test, while a close contact that is symptomatic or that returns a positive RAT test should have a PCR test.
