FAQ

Does Route 637 operate on public holidays?

To check holiday operating times for Route 637, select the holiday week from our calendar and find the specific day.

Our timetables are organized by week (e.g., 10 March - 16 March) and follow service patterns. If a public holiday falls on a specific day—such as Thursday—check if that day (Thursday or your chosen day) is listed in the timetable. If it appears, the route operates as shown; if it’s missing, there is no service on that holiday.

Always check the published schedule for accurate holiday availability.

Are there maps available to view the Route 637 journey?

Yes, interactive maps are available for all Route 637 journeys. To view these maps, simply click on any specific departure time in the timetable. You'll notice each time displays a superscript letter (for example, 08:00^A, 09:00^B, 10:00^A). These letters indicate journey patterns - identical letters represent identical routes.

For instance, if 08:00^A and 10:00^A share the same letter, they follow identical routes, while 09:00^B takes a different path. Always check the specific journey map for your intended travel time as routes may vary throughout the day.
