Proactive Investors - Train passengers faced their third day of train strikes in the last four as drivers from union Aslef in their long-running pay dispute.
Services were hit at services operated by c2c, Gatwick Express, Greater Anglia, Southeastern, Southern, South Western Railway, Great Northern and Thameslink.
East Anglia and the South East were the worst affected in a dispute that is now approaching two years with no talks or proposals to end the conflict.
Overtime bans on Monday and Tuesday will further disrupt services, according to Aslef, which estimates the dispute has so far cost £2 billion.
Mick Whelan, Aslef’s general secretary, added that support for the action among its members remains solid.
For the train operating companies, Rail Delivery Group said: "Train companies are working through plans to manage the unnecessary disruption to our passengers caused by this damaging industrial action.
"We remain committed to resolving this dispute and our offer, which would take average driver salaries to £65,000 for a four-day week without overtime, remains on the table."
New laws were introduced last year to ensure minimum service levels during strikes, but these have yet to be adopted by any of operators.
