London commuters are facing more travel disruption on Thursday as an overtime ban by Aslef train drivers continues.
The nine-day action is running alongside a series of rolling strikes by union members.
Walkouts will take place at LNER, Greater Anglia and C2C on Friday, at Avanti West Coast and East Midlands Railway on February 3 and at Great Western, CrossCountry and Chiltern on February 5.
Meanwhile commuters who rely on the Central Line are facing another morning of disruption with a shortage of trains once again causing severe delays to the London Underground's busiest service.
