Three services were cancelled on the T3 line due to one train not being at its scheduled location and two other trains requiring mechanical repairs. Two more services were cancelled on the T2 and T8 lines due to trains requiring mechanical repairs, Sydney Trains said.
On Thursday night, passengers took out their frustration on Twitter, with many wondering why an incident on one line hours earlier had crippled the entire network.
Delays began on Thursday afternoon, when the track closure at Burwood was further compounded by signalling issues at Strathfield, Petersham and Summer Hill.
Buses were placed on standby at Campbelltown, Hornsby, Lidcombe, and Penrith to take some of the load from disrupted train services along the T1 Northern & Western, T2 Inner West & Leppington, T3 Bankstown and T8 Airport and South Lines.
The tracks had been cleared by 2pm after the fatality occurred on Thursday morning, but additional signalling issues at Strathfield, Petersham and Summer Hill compounded the delays, with multiple lines affected.
A spokesperson for Sydney Trains said customers should plan ahead, allow extra travel time, listen to announcements and check indicator boards and real time travel apps.
A “regular service” was running, but trains remained delayed and out of order on Thursday evening. Services had returned to normal by Friday morning.
On Thursday night, updates from Sydney Trains’ Twitter accounts urged commuters to “consider delaying your journey or using alternative transport”.
