It was mentioned on BBC Look North this afternoon that the Newcastle Clean Air / Low Emissions Zone will now be launching later this year.

Will Stagecoach be upgrading the exhausts on the remaining MAN ALX300s and older ADL E400s at Walkergate and Slatyford, or will the vehicles be swapped around assuming no new buses are on order?

The owners of any bus that does not meet the clean air / low emissions requirements will be charged which I assume is what all bus companies want to avoid.
