A seal named Albert had to be shooed away from railway tracks in Wellington by maintenance staff.
Crew were surprised to find the wee mammal overseeing their maintenance work near the Wellington Rail Yards on Friday afternoon.
Traction electrician Caleb Scott said the seal was sitting near the tracks under the motorway overpass, watching them work.
"As we moved along the track doing our work it followed our path from the other side of the tracks," Mr Scott said.
"We notified train control to let them know just in case the seal made a mad dash onto the tracks.
