Large parts of the country have no train services because of a fresh strike by drivers in a long-running pay dispute. Members of Aslef at Avanti West Coast, CrossCountry, East Midlands Railway, West Midlands Railway and London Northwestern walked out on Friday, mounting picket lines outside stations. All five train operators said they are not running any services, with passengers urged not to attempt to travel. Report by Covellm.
