As I stay at the new builds next to the college on the rare times of me not getting the tram from Bankhead my only preferred option would indeed be the X27/X28 at Sighthill. So I would say I am spoiled for choice of getting into town and also the airport for that matter.
Slapping in another express/limited stop service such as the X25 would be very welcome!
Before the pandemic there was the X25 weekdays at peak times as well as the X27, X28 and also both the X22 and X23 (First services).
I do think that there is still a demand for express services from the city centre to areas further out although most are covered by other operators.
The Jewel/ Duddingston area is covered by the X5, X6, X7 and 253.
Fort Kinnaird has the 253.
South Queensferry and Queensferry Road area is covered by the Fife express services and the 43.
Calder Road area is covered by the X22, X27 and X28.
South Gyle area is covered by the 22.
Newbridge, Ratho Station, Gogarburn annd Corstorphine area is covered by the X18, X24 and X25.
North Edinburgh isn’t too far by bus so the 8, 14, 19, 24, 29, 37, X37 and 47 have this area covered.
Leith/Newhaven area is covered by the 7, 11, 14, 16, 25, 34, 35 and 49.
Portobello area is covered by the X26 at peak times Monday to Friday only. At other times it only has the slower 26.
Milton Road area has the X44, 113 and 124.
Niddrie/Craigmillar doesn’t have an express service, only the 30 which could be made quicker, however people could walk from Magdalene near The Jewel but it is a long walk.
Royal Infirmary has the X33 peak time service but it doesn’t go into the hospital. The 33 is a quick route from the city centre though. There is also the 51 and X95 which serves the same road at other times.
Gilmerton has the X29 peak service.
Mortonhall/Liberton has the X31 and X37 peak time services and the X62.
Fairmilehead has the 15 and 101/102.
Oxgangs/Colinton Mains don’t really have an express service from the city centre.
Wester Hailes/Clovenstone has the 30.
Balerno/Currie and Juniper Green currently have no express service to the city centre.
There is room for improvement here for express services from the city centre to the outskirts of Edinburgh and potentially further out.
I think that even if one 29 bus per hour ran as an X29, one 37 ran as an X37 and so on it may make a big difference to people using the bus more. Those are just a few examples.
