If you were to get off the 8 at Pelton Bridge @ either 22 or 52 mins past, you could quickly make your way and stand on top of the bridge to catch the 22 #78, 25 #28 (55 #28A) or 00 #8 heading down to Chester (or Newcastle for the 28s).
Also, aureolin mentioned Northlands. If you stood at the left-hand top of Blind Lane, you could easily get a fair lighting from the sun in both directions, and should you hang around for about 10 minutes, you could snap two or three shots.
Hope this helps, Jimmi.
