Extra X21

East Yorkshire's annual 'fast' summer service X21 between Hull, Beverley, Bridlington, Filey and Scarborough has been enhanced for 2019. It is East Yorkshire's only through service from Hull and Beverley to Filey and Scarborough (otherwise connections are available at Bridlington). The rail service from Hull, Beverley and Bridlington to Filey and Scarborough was increased to hourly at the May rail timetable change, and from Hull to Bridlington there is also extra competition from Stagecoach's new 99 this year.

The usual daily 0915 from Hull Paragon Interchange and 1615 return from Scarborough remains, having started on 25th May, although ending on 1st September this year rather than 15th September as in 2018. However for 2019, a second journey each way, leaving both Hull and Scarborough an hour later (at 1015 and 1715), also operates on weekends and during school holidays (including bank holidays); again this runs from 25th May to 1st September.

At least one of the two round trips is being operated by a coach this year.
