I didn't see 1BCamdens comments, apologies, but the first shot is definitely Camden, or more accurately Primrose Hill heading north.
The date of Jul 62 is reasonable, wires didn't go up around Euston until around 65 although infrastructure work started earlier.
Wires up is one of the last stages before services start and electric trains started working south with change overs as the OHLE progressed, Stafford, Rugby, Nuneaton were all change over points during the project.
Over the years I've collected a lot of photos of this period (60-66) from Crewe to Euston as this period I find most interesting with the mix of steam, diesel and electric, I'm trying to find how far south the wires were up in Jul 62 and it's not that far south of Stafford.
Having said that, if we ignore the date and assume it's sometime in the 60's, I still cannot fathom where the second photo is, the track is on might help as part of the WCML is 1+2+1 (slow, fast, fast, slow) but most is 2+2 (slow, slow, fast fast) with the fast lines being to the west side south of Stafford/Trent valley and east side north of Stafford.
What's really annoying is the second shot feels very 'comfortable' which generally means I know where it is and have been here, the ground level signal box (I'm sure that's what it is now) tends to suggest a junction and it does look like there might be a line merging from the right hand side.
A slightly larger close up of whats behind the bridge might help as there's some sort of structure there.
I will find it, there are only so many places with 4 tracks, a 90° span bridge on a rising grade with left hand curve.
