Became 580/581 (ex-39, 40) c.1969, I think.
Some Pennines went all the way to Lancaster
In the middle of the day, Monday to Saturday, a Pennine would run through to Lancaster every three hours, so at any one point in time there was a Pennine west of Ingleton. There was a three-and-a-half hour gap between the first one of the day (starting at Ingleton) and the second (originating at Skipton), this was to enable the first one to run through to Morecambe.
and Ribble buses did turn up in Skipton on this route.
During my time with Ribble (on and off, 1968-78), Ribble only ran east of Ingleton on a Sunday. In 1968 the 0948 Lancaster-Skipton and return (1235, I think) was worked by Ribble's Lancaster depot (with a two-man crew!), and the 1548 and return (prob. 1835) by Ribble's Ingleton depot (one-man, I think). Around 1969 the 0948 was changed to an Ingleton depot working (one-man, I think). These were journeys which, on Mondays to Saturdays, would be worked by Pennine (Ingleton depot). Pennine Skipton depot journeys operated on Sunday the same, I think, as Monday to Saturday.
(The Manchesters, Prestons and Eattby locals were Ribble too.)
If I remember correctly Ribble's Skipton depot provided two vehicles for the Manchester service (X43 - after 1962 these were usually 'White Lady' Atlanteans), so the other 4/5 vehicles needed for the service would have been provided by other depots (possibly, just Burnley).
The Preston service (X27) for many years ran through to Southport, but I think there was always a crew change at Preston. I can't remember how many vehicles Skipton depot provided, it may have been just one.
By 'Eattby' I presume 'Eastby' was intended, but I think the majority of journeys terminated at Embsay. Some continued through to Bolton Abbey. I think this service was worked entirely by Skipton depot. (I say 'think', since I can't rule out the possibility of some interworking with the X27).
Pennine didnt have route numbers on their buses (actually coaches) then.
In the early 1960s Pennine's fleet was a mixture of service buses and what would be considered DPs (such as the Duple Doningtons). The Leyland coach-bodied Royal Tiger was, of course, built as a coach, but by the 1960s I would say it did mainly service work, like the rest of the fleet. I think that, for a few years, it was the regular Ingleton depot vehicle.
The arrival of a Plaxton Panorama bodied Leopard in 1965 seems to have been an attempt by Pennine to break into serious coach work, but coach work remained a minority activity and was ultimately abandoned. The fleet didn't become all-coach until at least the 1970s.
On the Pennines you got a Ribble ticket from a Setright.
This I can't remember, I thought Pennine used their own tickets, but I'll happily stand corrected on this point.
