I never used Yelloway's well-known routes to the South West, but I did have one experience of their service between Lancashire and East Anglia.
In the early 1980s, I needed to make several journeys between Wigan and Cambridge in quick succession. With no access to a car at the time and with the cost of train fares mounting up, I decided to give Yelloway a try with a return trip. I knew they had a solid reputation as a good and popular coach operator, so I had expectations of a satisfactory trip with a few ££ saved.
First journey was from Bolton to Cambridge, on what may have been the Blackburn or Rochdale to Clacton route. It was one of Yelloway's signature yellow & orange AEC Reliances, which offered uncomfortable, narrow seats and shabby interior. The all-day cross-country journey (stopping in places like Leek and Leicester) was an interminable series of rough gear changes and badly executed cornering along single-carriageway A-roads, with hardly a motorway to be seen.
Subsequently, I've read that the manual gearboxes on Yelloway's fleet of AECs "took a bit of getting used to", and saw mention that it might take a new driver six months to become proficient. Maybe so, but I suspect a significant contribution came from our scruffy, surly and seemingly disinterested driver not giving a **** (maybe
@lincman knew him??)
The return journey from Cambridge to Wigan (final destination Blackpool IIRC) was operated by a Premier Travel coach and driver (Premier was a joint operator on this route) and a whole different kettle of fish - smart, new blue vehicle with comfortable seats, a cheerful, helpful driver (who obviously knew a thing or two about how to drive a coach) and an enjoyable trip back to the North - albeit via a different route with a fair bit of motorway running in this direction.
After this dabble spending a whole day with Yelloway I decided (on a sample size of 1) that despite more expensive fares, Inter-City really did make the going easy and went back to BR.
