Trains to and from Clapham Junction are facing disruptions, affecting commuters heading towards Wimbledon.
Train services running to and from this station may be cancelled, delayed or revised until 8.30pm.
Minor delays continue to hit the Central Line amid an ongoing shortage of trains.
A new report is warning the Bakerloo Line is “in a state of managed decline” and at risk of “critical failure” unless it can replace its 52-year-old trains.
