A traffic cop was shocked when he pulled up to deal with a collision on a motorway and a train went past him.
Dave, a traffic cop for West Yorkshire Police, said he stopped to deal with a collision on the M606 in Bradford when he spotted the unexpected carriage.
He posted a video of the bemusing moment on Twitter.
Many users jokingly referenced HS2 and Thomas the Tank Engine - while one user even asked “is the train on time?”
BTP London replied: “Put the Thomas the Tank engine theme song to that and you've got a YouTube hit!”
Nick Ainsworth said: “Chuffin’ hell!”
James Moran jokingly tweeted: “Not quite what I was expecting HS2 to be.....”
