Irish Rail and Dublin Bus services are resuming after being disrupted by Bus Eireann pickets this morning.
Virtually all trains and buses were cancelled with management saying it was completely unexpected.
Union bosses say they were also taken by surprise, and called on members to return to work.
The Transport Minister Shane Ross has called morning's action an 'orchestrated ambush' of the travelling public.
And repeated again that he will NOT interfere in the dispute.
