Members of the RMT union are staging a 24-hour walkout over Northern Rail's refusal to rule out running some services without train guards.
The union says the strikes are about "putting the safety and security of the travelling public before the profits of private companies". They blame Government policy for forcing companies to make changes to the on-board conductor role.
