The capital’s commuters waste 1.9 million hours each month waiting for delayed Tube trains.
The cause of delays of more than two minutes include signalling problems, strike action, safety and security concerns, and the state of train tracks, City A.M. reports.
According to figures released by the London Datastore, the most frequent cause for delays in the past year were faulty or unavailable trains – which snatched 380,000 hours from commuters, followed by customer behaviour and absent staff.
Planned engineering works - the bane of many a commuter's life on weekends - are not included.

The 1.9 million hours lost to commuters mean 13 minutes per month are taken from every Londoner.
London Datastore has said lost customer hours on the Tube in 2014-15 is six per cent fewer compared to 2013-14.
Commuters are likely to use the Tube increasingly for journeys when the network launches its night-time service on 12 September on Fridays and Saturdays for the Jubilee, Victoria, Northern, Piccadilly and most of the Central lines.
