A STRANGE blue light has been spotted in the skies over Kempsey.

However, there is no need to call the X Files just yet as the light has a more down-to-earth explanation.

A Network Rail spokesman said: “The blue light residents in the Kempsey may have seen was from one of our measurement trains, which records the tracks and the structures to the sides, above and below them to make sure they're in full working order.

“The blue light seen in the sky is part of a measurement system that monitors the amount of wear on the overhead line created by train pantographs sliding along the underside of the contact wire.

“The data is used to prevent de-wirements caused by the overhead line breaking as a result of the wire wearing too thin.

“Our measurement trains play a vital role in maintaining the railway – helping us to spot potential faults before they affect services.”
