Train services are being hit by more strike action this week.

Workers who are members of the Rail, Maritime and Transport union (RMT) will strike on Friday, while train drivers who are members of Aslef will walk out on Saturday.

It comes after members of Aslef walked out on Wednesday, meaning several operators such as Avanti West Coast, CrossCountry, Northern and Thameslink were running no trains.
