People intending to travel via train in North Yorkshire this weekend are being warned of disruption.
Trains along parts of the East Coast Main Line are being replaced by buses due to engineering work.
National Rail said the works are taking place today (Saturday, September 26) and tomorrow.
York-based train operators LNER and Northern services are affected, along with CrossCountry, Lumo, ScotRail and TransPennine Express.
Engineering works are closing all railway lines between Newcastle, Dunbar and Edinburgh, with no trains running on several routes.
