Derailment at Concort West

[Robert Prentice <c9605190@alinga.newcastle.edu.au>]

Regarding the derailment at Concord this morning.. I heard that Northern
Line trains were terminating at Epping, with buses to Strathfield to join
trains to the City. Was this the go all day? Does anyone know what
happened yet? Apparently they were doing about 80km/h.. was it a track
problem that could've occurred a couple of hours later when full commuters
were heading into the City? Heard nothing this morning about 5.20am at
Newcastle.
