The London Underground is ranked among the world's best metro networks. It features prominently during capital residents' daily commutes - arguably the most irritable part of the day, so it naturally attracts its share of grumbles.

Covering nearly all of London, its massive scale contains some quirks and curiosities that transport enthusiasts love. One such curiosity could be the Tube's most futile trip. This journey involves the brief jaunt between Covent Garden and Leicester Square, two stations remarkably close together. The journey lasts just 45 seconds on the Piccadilly line, yet once you account for waiting for the train, tackling the staircases and clearing the ticket gates, simply walking the five-minute distance might prove faster. TfLitself recommends cycling or walking instead, which suggests it's unlikely to be worthwhile.

Nevertheless, the Covent Garden to Leicester Square route remains popular, with more than 250 Londoners completing the trip daily. Meanwhile, more than 150 Londoners make the reverse journey, from Leicester Square to Covent Garden, each day.

There are also other Underground journeys across London that might actually be faster to complete on foot.

For example, travelling between Shepherd's Bush Market Station and Goldhawk Road Station on the Circle and Hammersmith and City lines takes just one minute.

The trip from Hyde Park Corner to Knightsbridge, where both station entrances are actually visible from one another, requires only three minutes of your time.

Another brief Underground journey runs from Oxford Circus to Bond Street, lasting just one minute on the Central line.

However, if you prefer to walk, the distance between these two stations takes only five minutes - though this could extend considerably on busy days when Oxford Street is packed with shoppers.
