Can you see which train is going in the wrong direction?
A new brainteaser has left people scratching their heads as they attempt to find out which train is going in the wrong direction in the picture.
The brainteaser was created by Heathrow Express UK and can be solved if you spend a few minutes to “look closely”.
"This puzzle is a bit of a head-scratcher but the train is in there somewhere if you look closely.
"Thankfully catching the right train in real life is much easier – especially if you travel the smart way."
