Services on the rail line between Sligo and Dublin are being delayed because of a collision with cattle near Kilcock.
The incident does not involve a Sligo train but rather a special train travelling between Connolly Station and Mullingar.
However, the single track line is blocked at the location as veterinary staff are awaited.
It's understood a cow is badly injured and will have to be euthanised.
Irish Rail spokesman Barry Kenny spoke to Ocean FM's Harry Keaney in the past half hour.
