Damaged overhead electric wires in the York area are causing major disruption at the station - with passengers warned to delay travel until tomorrow.
Trains may be cancelled, delayed by up to 70 minutes or revised, LNER told passengers on their website.
Tony Walker, Station manager for Acomb & Huntington, confirmed three trains were currently stopped in a series of tweets.
He said an assessment was being made by network rail to establish if overhead lines can be lifted to allow the trains to proceed.
Fire crews are assisting with welfare, lighting and plans to evacuate if required, Mr Walker said.
Pictures show crews stood with one of the trains while assessing the damage.
The disruption is set to last for the rest of Monday.
