People have been trying to figure out the origins of a mysterious blue light that appeared in Berkshire over the weekend.

Multiple photos were uploaded from different locations in Berkshire of the beaming light and people were quick to pin its origins on either aliens, drones, or the train line.

The blue light was spotted in Reading,Newbury, and Pangbourne.

Some said they thought that the blue light originated from the train tracks, where trains may have been undergoing tests.

Facebook user Gina Woodman said: “It’s the train, it’s a light that beams up to check the overhead electric lines, I see it at 6.30 the other morning and freaked me out! Lol”

Kieran Bennett said: “It’s a light on top of a train it came through Pangbourne about midnight yesterday (November 20).”

Another Facebook user claimed that he’s seen it multiple times before.

Kevin Greenroyd said: “I fish next to the track and see this quite often at night.

“It is pretty weird the first time you see it but definitely from the train tracks.”

Others said it could be aliens or a UFO and one user called Mark Prior jokingly said: “Totally, one hundred percent, Newbury aliens coming to take over the middle classes.”

It seems, however, that there may be a much simpler explanation for the blue light.

A spokesperson for Network Rail said: “The blue light seen near the railway in the Reading and Newbury area 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.”
