Urgent signal repairs caused unexpected delays on the T4 Eastern Suburbs & Illawarra Line and South Coast Line, with officials advising up to 30 extra minutes of travel time and sudden platform changes.
A shuttle service linked Cronulla and Sutherland, while services past Waterfall ran on schedule; repairs wrapped up by 9pm, though some gaps lingered into the morning.
The disruptions, linked to a broken rail at Como, affected thousands during peak hours and echoed other recent issues like Burwood signal work, as one rider noted the frustration of added 10-15 minutes on trips from Cronulla and Waterfall.
