This unbelievable video was reportedly captured earlier this month by CCTV cameras in Inner Mongolia's Baotou Railway Station. From Mysterious Universe:
Is this a video of a ghost train? The comments run the gamut from definitely ghost train to an image from a parallel universe to a secret military cloaking train to a reflection in a window of a nearby train to a hoax. The Daily Express online says the last scenario is supported by debunker Scott Brando, who claims it's a merger of two videos and dates back at least to 2012 to a railway station in not the Baotou Railway Station in Inner Mongolia but the Polezhaevskaya station in Moscow.
