Yet, more cost effective for Deptford to run them given Percy Main drivers would somehow have to get from North Shields to Jarrow and back agin at the start/end of their runs on those short trips, whereas Deptford would be able to do that at Park Lane. Add to the 3 buses running light through the Tyne tunnel 6 days in both directions and you'd see the operational costs per vehicle increase above the norm.
