A third day of strike action is set to disrupt railway services in the North East.
RMT members working for 13 operators, including several that run trains through Newcastle, Durham, Darlington and Northumberland, are set to walk out, along with colleagues working for Network Rail.
Northern will not be running any trains in the Newcastle area, or in Northumberland or much of County Durham. The only route it is keeping open in the North East is between Darlington and Saltburn, via Middlesbrough, with a reduced service.
