A woman has been killed after being hit by a train in Co Mayo.

It's understood that she was chasing her dog across a level-crossing near Straide, at around 11.30am this morning when the accident happened.

Services have been cancelled and the scene has been sealed off for examination. 

Gardai in Castlebar are currently investigating the situation.

Irish Rail's Barry Kenny says the line is unlikely to open again today and bus-transfers will continue until further notice.
