Day after day after day Londoners head out of their front doors knowing they are at risk of being late due to another delay on the London Underground.
Just last year alone, commuters lost over 22 million hours waiting for tube delays of two minutes or more in the capital.
The worst offender, was – unsurprisingly – the Central Line, which was responsible for 5,200,103 hours (23 per cent) lost in 2018.
However, the District line had the biggest number of delays at 198 last year.
Picadilly came second in hours lost at 4,063,771, followed by Jubilee at 3,491,059.
District was closely followed by Picadilly Line in the number of delays with 190, and – again – Central at 179.
In the time lost to train delays in 2018 on the Central line alone, one person could have flown around the world 101,962 times.
The hours lost equates to over £376 million in average hourly wages in London.
The Waterloo & City line lost the least delays with just 130,000 lost.
The research, conducted by Casino.co.uk found that almost 15 per cent of delays were caused by staff shortage.
