In the hustle and bustle of train stations it can be difficult to work out which one you need to catch – but this new brain teaser is even harder than the real thing.

The puzzle shows a series of trains heading to their destinations, but one is going in the opposite direction to the others – and it’s tough to work out which. 

Among the different coloured trains hurtling along the track, can you see which one is on a collision course? 

A new brainteaser shows trains leaving a busy station, but one is going the wrong way - can you work out which?

The answer is the purple and cream train in the right hand corner of the sixth row from the bottom.

The two other trains in that line are all heading west, while the odd one out is heading east.

This means when it gets further along the track it is headed straight into a collision with the next train on the move.

The brainteaser was created by Heathrow Express, whose spokesman said: ‘This puzzle is a bit of a headscratcher but the train is in there somewhere if you look closely.

This isn’t the first brainteaser to leave netizens from around the world scratching their heads. 

Last year a puzzle, which was shared on by Twitter user @Purp, showed a pot of coffee being poured into a sketch of different pipes, which collectively lead to four coffee mugs.

The puzzle asked users to figure out which of the coffee mugs the liquid will reach first – and it’s harder than it first appears. 

The user who uploaded it told her followers: ‘Let’s see whose brain is working’. It was quickly shared thousands of times as users argued over the right answer.

While many people concluded that all four cups would receive the coffee at the same time, user @Purp encouraged them to ‘look closely’.

Her followers continued to guess which cup would receive the coffee and she kept telling them to pay attention because the answer was ‘right there’. 

The correct answer? Cup five. Why? Because all the funnels leading to the other mugs are blocked.

Once the poster had pointed that out to her followers, they were amazed how long it took them to notice that detail.
