Some people describe "nightmare" journeys as they try to cross London, while others say their commutes have been similar to normal
The RMT says it had "no alternative" but to take action, but TfL insists the changes it has proposed are "voluntary" and has called on the RMT to suspend plans for further strikes
Another 24-hour strike is set to begin on Thursday - here's what you need to know
Members of the Rail, Maritime and Transport union (RMT) are taking action over plans to introduce a voluntary compressed four-day working week.
The union argues the proposed longer shifts could lead to fatigue and impact safety.
TfL says the changes are optional and would give drivers more days off without reducing pay.

However, disruption is expected to begin earlier and continue into the evening after the strike ends.
TfL says services will only begin recovering from midday on Wednesday.

More than two hours before the strike officially begins and we’re seeing disruption on the Circle line and the District line.
The TfL status checker, external is reporting severe delays which it puts down to the strike action.
In addition the Piccadilly line has minor delays due to the walkout.
This is something the transport body did predict, saying that services will begin to be affected by mid-morning onwards.
Elsewhere on the network, the Central line has minor delays as a result of "train cancellations", says TfL.

No service is expected on the Piccadilly and Circle lines during the strike.
The Metropolitan line will not run between Baker Street and Aldgate, while the Central line is suspended between White City and Liverpool Street.
TfL says most other lines will be affected, with trains finishing earlier than usual.
Other services, such as the Elizabeth line, London Overground and trams continue to run but are expected to be busier than usual.
