My contact at First tells me that the new X1 timetable is now available online
The current road works at Postwick on the A47 near Norwich, has meant that the service will run in two parts from Sunday 27 July 2014.
As the road works are expected to last 18 months this change is being introduced as a temporary measure. Splitting the X1 route enables First to manage the service more effectively with the road works being monitored continuously
