So here is a timing sample of the 355 if extended to Holystone Park & Whitley Bay.
Evening & Sunday journeys would operate a slightly different route.
Timetable
Evening variation
Loop around Holystone, omits Clousden Hill and Glebe Road
Sunday variation omits Clousden Hill and Glebe Road only. Journeys to Whitley Bay additionally serve Holystone Park before or after Holystone and West Allotment.
