Trains are being delayed after reports of a vehicle hitting a bridge between Scarva and Portadown.
Northern Ireland Railways has advised passengers that train services running through both stations will be delayed
“Disruption is expected until further notice,” according to NI Railways.
There are no further details at present.
Meanwhile, an overturned cattle trailer between Junction 11 and Junction 12 (Birches) had closed a lane on the M1 motorway.
It has since been cleared but delays can still be expected.
