Brain, well the engine is AWS and speedometer fitted so that makes the date (roughly as I don't have the referance books here) after 60-61, OHLE flashes also confirm that as they appeared around that time.
My first thought was Crewe North, but this area would be sharply curved to fit inside the Chester lines and it feels too open to be Crewe North, that spire in the left background and tower in the right back ground niggle me so I'm going to hedge a good bet it's Holbeck, simply because I think I've used those reference points in one of your other shots.
I'll check when I get home, or a chance to go back through this thread looking at the previous Holbeck shots, but fornow I'd opt for Holbeck.
Those big LMR tenders really bulk out the Britannia's look, whilst I still like the stepped version, certainly on the GEML trains, these big high sided ones do change the whole look of the engine and have a visual edge over the others. My Severn Models kit has one of these, I've not yet found a picture of one on the ECML, more specifically on the southern GN end at the Cross, shame as that'd be the engine I'd pick. Other than that the high sided tenders were attached to engines with pretty boring names on the whole, making a suitable choice for me quite difficult. The LMR hand holds in the deflector are also a nice touch, much neater than the letter box style ones from the WR, and no, i haven't open the kit box just, but my resolve is becoming weak
