which station

[gwendolyne w]

which london station do direct trains to doncaster leave from

[KebabMeister]

Kings Cross - Great Northern Line, usually operated by GNER.  It usually stops in Peterborough, sometimes Grantham, York and then Doncaster.... I think!  Do check the time table because depending on which train it is it doesn't always stop at all the stations.
