So has 36474 had a new engine or just exhaust modifications?

When will the Clean Air Zone come into effect in Newcastle, assuming it has been delayed due to COVID-19? Will the remaining MAN ALX300s, Ex-Scottish MAN E300s and 193xx / 194xx ADL E400s be replaced, swapped or upgraded to Euro 6 in the next few months?

If the CAZ is still going ahead as planned then surely the North East will be on the priority list for orders this year?
