Train work?
The light was caused by a laser used by Network Rail to make sure that workers don’t enter a particular zone during railway works.
The high output ballast cleaner is used to clean the ballast – the stones and gravel on the railway line.
Lasers are used to mark where the workforce cannot go and the result is the mysterious glow.
A spokesman for Network Rail said: “We can confirm this was not an unidentified flying object (UFO).
“It was rather an identified non-flying object (INFO) – namely a railway ballast cleaning machine, which uses lasers.”
