Thameslink is more frequent. LNER have gaps in their timetable - eg the last one back is 1933 from Kings Cross. You can reserve LNER seats on their website but you no longer have to.Going to have a day out to London from Stevenage on bank holiday Saturday.
Which service is better lner or thameslink?
Do I need to reserve seats? How do I do that?
Any advice really welcome.
