Trains between Exeter and Exmouth disrupted.
Rail services are delayed or cancelled as emergency services deal with an unexploded WW2 bomb near train tracks at Lympstone.
In a statement, British Transport Police said: "We were called at 12.43pm on 08/05 to a report of a suspected WW2 grenade which has been found a distance away from an area of rail line near Exmouth Road in Lympstone. BTP officers are currently at the scene. An EOD team is en route."
Train services are currently running, but Network Rail says it expects a further line blockage "at some point today". Check updates from them here.
