Slatyford too have eight, all of which need exchanging for Euro 6 vehicles, however that would leave Shields with only five. The 10/11 requires six, although 36961/3 have worked this weeks suggesting perhaps the 10/11 isn't Euro 6 critical now? The 516 certainly has seen more Euro 5 than 6 of late.
I was under the impression that 36468-77 had received modifications a couple of years ago to make them Euro 6. They all say 'No Charge' when using the online checker.
