Mark Levy has slammed RTBU NSW Secretary Toby Warnes, calling him a "goose" over a text message scandal rocking Sydney’s rail network.

As commuters endure yet another day of mass delays, a leaked message from an RTBU convenor urged rail workers to "f**k the network up."

The text, sent to members on Thursday night, has sparked outrage—but during a press conference, Warnes distanced the union from the message, suggesting it wasn’t from the RTBU.
