LATEST: Peak hour pain in Melbourne as ‘multiple’ trespassers spark commuter chaos

Multiple trespassers on train tracks have sparked commuter chaos in Melbourne.

All lines are now experiencing “major” delays, as Tuesday hour peak begins.

Commuters are being told trains may hold at platforms while the issue resolved.

And the news only gets worse for those on the Cranbourne and Pakenham lines, with major delays also caused by a train fault between the Flinders Street and Caulfield area.

More to come.
