Commuter chaos on western and Blue Mountains train lines after train gets tangled in overhead powerlines TWELVE HUNDRED rail commuters have been evacuated off two trains in western Sydney this morning after overhead wires became tangled on a train near St Marys. Emergency services were called to help stranded passengers about 100m short of the station just after 6.30am. The two trains were full with early morning commuters heading to work. Buses are also on route to ferry passengers to their destinations. "Customers on the Western Line and Blue Mountains lines are being advised to delay their journeys with services on both lines closed this morning due to an overhead wiring problem near St Marys," a Sydney Trains spokesman said this morning. Both lines are now partially closed between Penrith and Blacktown after the overhead wiring became tangled about 6.50am. Urgent repairs are now underway but major delays are expected and customers are urged to delay their journeys, allow plenty of additional travel time, listen to station announcements and check indicator boards. Buses are being sourced to operate from Penrith to Blacktown this morning but customers are advised major delays are expected.
