I took this up with the City Council’s Team Leader, Parking & Sustainable Transport who has now advised me as follows :
“I have spoken to the commercial manager at Stagecoach East Scotland who has confirmed the 'temporary' suspension of X54 between the city centre and Ninewells.
The longer term future of this express service will depend on passenger numbers returning to something like pre-pandemic levels. If this does not happen, it is possible that Stagecoach will curtail the X54 service in the city centre and passengers travelling from Fife will be advised to change buses for onward connections to Ninewells.
If that scenario were to happen, the commercial manager has indicated it is possible that Stagecoach East Scotland may then consider diverting another bus service (e.g. Service 39) so that some journeys serve the most westerly section of the Perth Road.”
I have asked to be kept updated as the loss of the X54 service is of real concern in this part of the Perth Road given the dearth of bus services there.
