A power supply issue is causing delays for all services heading out from the city this afternoon on the rail network.
Passengers are urged to allow extra travel time as urgent power supply repairs are underway.
On the T1 line, services from Epping via Strathfield were delayed by roughly 30 minutes.
Services to Berowra were running 15 minutes late.
The T8 airport line is 38 minutes behind, while the T3 Liverpool and Lidcombe services are up to 45 minutes late.
The T4 Waterfall and Cronulla line seems to be running on time.
Previously, interruptions to services in the morning have caused flow-on delays for trains in peak-hour during the afternoon, so it looks like it may be a long trip home.
More to come.
