COMMUTERS were left baffled by a sign displaying an obvious warning at Charlbury railway station. 

The sign, which read 'CAUTION TRAINS OPERATING' and stood just a few yards from the track, left some travellers confused by its presence yesterday morning. 

Keith Allen contacted the Oxford Mail and said: "It struck me that there's something here that needs to be exposed. 

"A friend of mine, Michael Kearns, who sometimes travels in to work from his Charlbury home by train, spotted this sign at Charlbury Station yesterday morning."

The Oxford Mail has contacted Great Western Railway for a comment.
